Computer language with code

 Array  Array  Array is defined as an ordered list of homogeneous data element. May be of type int, float,char or double  All these element are stored in consecutive memory locations An array is described by a single name or an identifier and each element in an array is referenced by a subscript  enclosed  in a pair of square brackets. Arrays are of two types:           One-dimensional arrays           Multidimensional arrays Two dimensional array Three dimensional array Four dimensional array One Dimensional Array(1D)               Arrays must be declared before they can be used in the program. The dimensionality of an array is determined by the number of subscript present in the given array. If there is only one subscript, then it is called a one-dimensional array.  Syntax:               type variable_name[lengt...

 Recursion  A function is said to be recursive if it can be defined in the terms of itself. Recursion is a programming technique that allows the programmer to express operation in terms of themselves. In C, this take the form of a function that  call itself. Syntax:               void recursion() {                         recursion(); } Program: write a program to find out the factorial of  a number using Recursion function. Code: #include<stdio.h>                                                                        int factorial(int x)  {   if(x==1)   return 1;   else    return x*factorial(x-1);  ...

 C Output Function  C programming language provides built-in functions to perform output operation. The output operations are used to display data on user screen (output screen ) or printer or any file.  printf() function  The printf() function is used to print string or data values or a combination of string and data values on the output screen. Syntax:      printf("message to be displya"); program-Write a program to print "hello world " using printf(). Code: #include<stdio.h> void main() { printf("hello world"); } Output: hello world -------------------------------- we used    the printf() function to print a string on to the output screen  The printf() function is also used to display data values. when we want to display data values we use format string of the data value to be displayed. Syntax:                    printf("format string ", varaibleName); program: #include...

 Types of function  Types of function  program:- add two number with all categories i) Functions with no arguments and no return values. Syntax: function_name() { valid C Code; } code- #include<stdio.h> void sum() { int x,y,z; printf("Enter two no's "); scanf("%d%d",&x,&y); z=x+y; printf("sum of %d & %d =%d",x,y,z); } void main() { sum(); } Output- Enter two no's 95 36 sum of 95 & 36 =131 -------------------------------- ii) Functions with arguments and no return values  Syntax: function_name(argument1,argument2,- - - - - - -,argument n) { Valid C Code; } Code: #include<stdio.h> void sum(int x,int y) { int z; z=x+y; printf("sum of %d & %d =%d",x,y,z); } void main() { int x,y; printf("Enter two no's"); scanf("%d %d",&x,&y); sum(x,y); } Output: Enter two no's12 32 sum of 12 & 32 =44 -------------------------------- iii) Functions with arguments...

 Functions- Functions in c language  A function is group of statements that together perform a task. Every C program has at least one function, which is main(). Every function has a name and it is reusable. It can take parameters called as argument. Properties- Every function has a unique name. This name is used to call function from "main()" function.  A  function can be called another function. A function is independent and it can perform its task without intervention from or interfering with other parts of the program. A function returns a value to the calling program. this is optional and depends upon the task your function is going to accomplish. Structure of a Function <return type>FunctionName(Argument1,Argument2,Argument3..............) {                                                      ...

 Nested loop  C programming language allows to use one loops inside another loop is know as nested loop  Syntax: for(init;condition;increment) {     for(init;condition;increment) {     statement(s); } statement(s); } p1-program to print following pattern 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5  program- #include<stdio.h> void main()  { int i,j; for(i=1;i<=5;i++) { for(j=1;j<=5;j++) {   printf("%d ",j);} printf("\n");}  } P2-program to print following pattern  1  1  1  1  1  2  2  2  2  2  3  3  3  3  3  4  4  4  4  4  5  5  5  5  5 program- #include<stdio.h> void main() { int i,j; for(i=1;i<=5;i++) { for (j=1;j<=5;j++) { printf(" %d ",i);} printf("\n"); } } P3-Program to print following pattern   * * * * *  * * * * *  * * * *...

 For Loop  A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. Syntax- for(variable int; condition ;variable update) {     statement; } program1-write a program to print "hello Word" five time  code- #include<stdio.h> void main() { int i; for(i=0;i<=5;i++) { printf("hello\n"); } } output- hello hello hello hello hello hello -------------------------------- program2-Write a program to print 0to 10 number using while loop code- #include<stdio.h> void main() { int i; for(i=0;i<=10;i++) { printf("%d\n",i); } } output- 0 1 2 3 4 5 6 7 8 9 10 -------------------------------- Program3-write a program to find sum of series 1!+1/2!+1/3!+1/4!+1/5!.......... code- #include<stdio.h> void main() { float fact=1,sum=0,i,n; printf("Enter the value of n"); scanf("%f",&n); for(i= 1;i<=n;i++) { fact=fact*...

While loop  While loop is also known as Entry Control loop because condition is checked at the entry of loop. syntax while(condition) { statement;  Increment/decrement; } Program1-Write a program to print 0to 10 number using while loop  code- #include<stdio.h> void main() { int i=0,number=10; while(i<=10) { printf("%d\n",i); i++; } } Output 0 1 2 3 4 5 6 7 8 9 10 --------------------------------------------------------------------------------- program2-write a program to find out the factorial of number using while loop. code- #include<stdio.h> void main() { int fact=1,i=1,number; printf("Enter a number to find factorial:"); scanf("%d",&number); while(i<=number) { fact=fact*i; i++; } printf("The factorial of %d is %d",number,fact); output- Enter a number to find factorial:5 The factorial of 5 is 120 -----------------------------------------------------------------------------------------...

 Assignment Operators(=,+=,-=,*=,/=,%=) The assignment operators are used to assign right-hand side value( Rvalue ) to the left-hand side variable(L value). The Assignment operator used in different variants along with arithmetic operators. Operator Meaning Example = Assign the right-hand side value to left-hand side variable A=15 += Add both left and right-hand side values and store the result into left-hand side variable A+=10 A=A+10   -= Subtract right-hand   side value from left-hand side variable value and store the result Into left-hand side variable A-=B A=A-B   *= Multiply right-hand side value with left-hand side variable Value and store the result Into left hand side variable A*=B A=A*B     /= Divide left-hand side variable value w...

Concept of Branching -if If statement is very frequently used in decision making and allowing the flow of program execution. The condition part should not end with a semicolon, since the condition and statement should be put together as a dingle statement.  Syntax if(condition) {      Statement;} Example-Write a code using if statement show input number is positive or negative  program- #include<stdio.h> void main() { int number; printf("Type a number "); scanf("%d",&number); if(number>0) printf("Enter number is  positive "); if (number<0) printf("Enter number is negative "); } output- Type a number 10 Enter number is  positive -------------------------------- //for negative number  Type a number -5 Enter number is negative -------------------------------- Q.N. which of the following are incorrect statements ? if int a=10. 1) if(a==10)      printf("Include Help"); 2) if(10==a)     pr...

 DATA INPUT  The input operators are used to read user value (input) from the keyboard.  The c programming language provides the following built-in-input functions. 1.  scanf() 2.  getcher() 3.  getch() 4.  gets() 5.  fscanf() scanf() function : The scanf() function is used to read multiple data values of different data types from the keybord. Syntax:             scanf("format strings",&variableName); Example : #include<stdio.h> #include<conio.h> void main() {     int i;        printf("\nEnter any integer value:");        scanf("%d",&i);       printf("\nYou have entered %d number",i);       getch(); } getcher() functn The getcher() function is used to read a characher from the keyboard and return it to the program. getch() function: The getch function is similar to getcher function. The getch() function is used to ...

Logical Operator  The logical operators are the symbols that are used to combined multiple condition into one condition.   Logical Operator with example Operator Meaning Example && Logical AND -Return TRUE   if all conditions are TRUE otherwise returns FALSE 8<5&&12>10 is FALSE || Logical OR- Returns FALSE if all condition are FALSE otherwise returns TRUE 8<5&&12>10 is true ! Logical NOT -Return TRUE if condition is FALSE and returns FALSE if it is TRUE !(8<5   && a2>10) is true Conditional operator  The conditional operator is also called a ternary operator  because it requires three operands. This operator is used for decision making. Syntax Condition? TRUE part :FALSE part; Example-write a code for conditional operator  program- #include...

 Arithmetic (+,-,/,%) Arithmetic Operators in C The arithmetic operators are the symbols that are used to perform basic mathematical  operations like addition , subtraction, multiplication, division and percentage modulo. Example-Write a program to perform all Arithmetic operation in c language  Program for Arithmetic operation #include <stdio.h> void main() {   int a, b;             printf("Enter the valur of the two number for performing the arithmatic opertion \n");       printf("Enter the frist number a::");       scanf("%d",&a);       printf("Enter the second number of the b::");       scanf("%d",&b);     printf("Arithmetic operator in C \n");  printf("this is value of a+b is %d",a+b); printf("\nthis is value of a-b is %d",a-b); printf("\n this is value of a*b is %d",a*b);     printf("\n This is value of a/b is %d",a/b); }...
