For Loop Statement - Control Structures

The For Loop Statement is an iteration statement that executes a set of code repeatedly, given the initial value, the condition,increment value.

Syntax:

Example :

#include <iostream.h> using namespace std; int main(void) { int i; for(i= 0;i<5;i++) { cout << "for loop has looped:: " << i << " ::times" << endl; } }

Result :
In the above example the "for" statement iterates starting with the value of i=0 till i is less than 5 everytime increasing the value of i by 1.

Example :

#include <iostream.h> using namespace std; int main(void) { int i=0; int j=0; for(;i<5;i++) { cout << "Value of j is:: " << j++ << endl; } }

Result :
In the above example, since the value of "i" is initialized before, the initialization value of the for loop is left blank. This is another way of declaring the for loop statement. This is iteration in C++.
