bookFor Loop

The for loop is more complex than the other loops and consists of three parts. Structure of for loop:

for (counter; exit condition; loop expression) 
{  
     // block of instruction 
     do_something;
}
  • Counter;
  • Exit condition;
  • Loop expression.

copy

#include <iostream>

int main()
{
	for (int counter = 0; counter <= 5; counter++)
	{
		std::cout << counter << std::endl;
	}
}
  • int counter = 0: iteration counter;
  • counter++: For each iteration, 1 will be added to the counter variable to mark the passage of the loop;
  • counter <= 5: loop termination condition. The loop will continue if the counter variable is less than or equal to 5.
