C++ For Loop





C++ language provides us a powerful loop through which we could execute statements in a loop(again and again), until the point when the boolean condition of the loop returns true. This loop is known as for loop and it has three segments -







The third segment of the for loop declaration i.e. iteration of counter can be intentionally left blank from its declaration and can be specified within the body of for loop. In other words, the counter of for loop can also be incremented in the body of for loop.

// C++ for loop example 


#include<iostream>

using namespace std;
int main() //main method starts
{

for(int counter = 0; counter<3; ) // counter iteration part is intentionally left 
{
	cout<<"counter = " <<counter <<"\n";
	counter++;		  // counter is incremented/iterated in the body of for-loop 
} 

return 0;
}// main method ends and program ends too


Output


counter = 0
counter = 1
counter = 2
