While Loop

Definition:

In C++, a while loop is a control flow statement that allows a block of code to be repeatedly executed as long as a specified condition is true.

Example:

    // C++ program to Demonstrate while loop
    #include <iostream>
    using namespace std;

    int main()
   {
	   // initialization expression
	   int i = 1;

	  // test expression
	  while (i < 6) {
		 cout << "Hello World\n";

		// update expression
		i++;
	}

	return 0;
  }
