In C++ a for loop is a programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement.

Syntax:

for ( variable initialization; condition; variable increment/assignment ) {
  Code to execute while the condition is true
}

Example Program

#include<iostream>
#include<conio.h>

using namespace std;

int main()
{

     // Variable Declaration
     int a;

     // Get Input Value
     cout<<"Enter the Number :";
     cin>>a;

     //for Loop Block
     for (int counter = 1; counter <= a; counter++)
     {
         cout<<"Execute "<<counter<<" time"<<endl;
     }

     // Wait For Output Screen
     getch();
     return 0;
 }
