Array in C++

Image
 Array:   Array in C++ 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 Syntax:               type variable_name[lengthofarry]; Program: Write a program take input and display the element using array in cpp. Code: #include< iostream> using namespace std; int main() { int i,arr[100],no; cout<<"Enter the number of element (less than 100)"; cin>>no; for(i=0;i<no;i++) { cout<<"Enter the element at"<<i <<" place"; cin>>arr[i]; } cout<<"Elemen in the arry is :"; i=0; while(i<no) { cout<<"\n"<<arr[i]; i++; } } Ouput: Enter the number of element (less than 100...

Function in C++

Image
 Function in C++  Function in cpp A   function is a group of statements that together perform a task. Every C++ program has at least one function, which is  main(). we can also say that A function is block of code that performs  specific task. Syntax of function:                            return_type  Function_Name(parameters){                                        code performs that task; } Types of function: There are two type function in C++ 1.Standard Library Functions:  Predefined in C++ 2.User define Function: C++ allows the programmer to define their own function . Program:  Write a program to find out the sum of two number using Function   in C++. Code: #include<iostream> using namespace std;  int sum(int num1,int num2) { i...

While & do while loop in C++

Image
 While in CPP . A  while  loop statement repeatedly executes a target statement as long as a given condition is true .  This is also a loop Structure , but is an enter-controlled one  Syntax: while( condition is true) {  action1; } action 2; Program : Write a program in CPP to count the number of alphabets ,digit and special Symbol                @#$%&)using while loop.  #include<iostream> using namespace std; int main() {           char  str[100];            int i=0 ,digit=0,alphabets=0,special=0,characters=0 ,count=0; cout<<"Enter the string :"; gets(str); cout<<"Enter string is "<<str<<"\n"; while(str[i]!='\0') { count++; i++; } i=0; while(str[i]!='\0') { if(str[i]>='0' && str[i]<='9') { digit++; } if(str[i]=='@' ||str[i]=='#' ||str[i]=='$' ||str[i]=='%'||str[i]=='^'||...

For loop in C++

Image
 For loop: The for is an entery entrolled loop and is used when an action is to be repeated for a predetermined number of times. Similarly When we have  executes same line of statement  repetitively is done by LOOP. Syntax: for(initial value; test; increment)        { action1; } action2; Program: Write a program to print 1 to 10 number using for loop . Code: #include<iostream> using namespace std; int main() { int i; for(i=1;i<=10;i++) { printf("%d\n",i); } } OUTPUT: 1 2 3 4 5 6 7 8 9 10 -------------------------------- Program2Write a Program in C++ to Print all natural numbers upto N without using semi-                                       colon(;) using for loop. Code: #include<iostream> using namespace std; int main() { int i , no; cout<<"Enter the number to print "; cin>>no; for(i=1;i<=...

If If....else statement in C++

Image
 If  in CPP if-block are executed only if -expression contain TRUE value. if statement consists of a  boolean expression followed by one or more statements. Syntax:    if (expression is true) {     action1; } action2; action3; Program: Write a program in C++ to find the greatest number in two numbers with the help of if Code: #include<iostream> using namespace std; int main() { int num1, num2;  cout<<"Enter the two number ";  cin>>num1;  cin>>num2;  if(num1>num2)  cout<<"Num1 is greatest number";  if(num2>num1)  cout<<"num2 is greatest number"; if(num1==num2)   cout<<"number are equal"; return 0; }   Output: Enter the two number 25 20 Num1 is greatest number -------------------------------- Enter the two number 10 32 num2 is greatest number -------------------------------- Enter the two number 10 10 number are equal -------------------------------- Q.n: What w...

Keywords Identifiers Constant in C++

Image
Keywords: The Keywords implement specific C++ language features. They are explicitly reserved identifiers and cannot be used as names for the program variables or other user-defined program elements. Many of Keywords are common to both C and C+.   Example:               break                     auto       case float If public short while Int Identifiers: Identifiers refer to the names of variables, functions, arrays, classes , etc. created by the programmer. They are the fundamental requirement of any language. Each language has its own rules for naming these identifiers. The following rules are common to both C and C++. ·          Only alphabetic charact...

 Variables  Variable size                                                                                                                                                                           Variable provides us  to store the data in System with named witch further can manipulate. In C++  Variable has a specific type, which tell the size and layout of the variable's memory.  Program: write a program to find out the average of two number take input from user...

C++ language with code

Image
What is C++? C++ C++ is an object-oriented programming language. It was developed by Bjarne Stoustrup at AT&T Bell Laboratories in Murray Hill, New Jersey USA, in the early 1980’s. Stroustrup , an admirer of Simula67 and a strong supporter of C, wanted to combine the best of both the languages that could support object-oriented programming features and still retain the power and elegance of C.     C++ is a superset of C. Most of what we already know about C applies to C++ also. The   most important facilities that C++ adds on to C classes, inheritance , function overloading and operator overloading. These features enable creating of abstract data types, inherit properties from existing data type and support polymorphism thereby making C++ a truly object-oriented language.   Application of C++ ·          Since C++ allows us to create hierarchy-related objects, we can build special object-oriented libraries whic...

Array in C programming

Image
 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...
