C++ While Loop

C++ Loops

Loops can execute a block of code as long as a specified condition is reached.

Loops are handy because they save time, reduce errors, and they make code more readable.

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

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

In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5:

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

Note: Do not forget to increase the variable used in the condition, otherwise the loop will never end!
