Answer to Question #146087 in C++ for Yazal

Question

What is while loop?

Answer 1

The while loop loops through a block of code as long as a specified condition is true:

while (condition) {
  // code block to be executed
}

Example:

int i = 0;
while (i < 5) {
  cout << i << "\n";
  i++;
}

In the example we print value of i and then increase it by 1 until it is less than 5. After i=4 we do i++ again, but this time the condition in while will be false, so the loop will not run again.
