C++ Programming Structure - Simple Explanation
Definition
In C++,a while loop is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. The while loop can be thought of as a repeating if statement.
Syntax
while ( condition ) {
Code to execute while the condition is true
