Repeating with while Loops

A while loop repeats a block of code as long as its condition is true. The condition is checked before every iteration of the loop.

snippet.c

int energy = 3;
while (energy > 0) {
    energy--;
}

Breakdown

while (energy > 0) {

The loop runs as long as the variable energy is greater than 0.

energy--;

Decreases the value of energy by one inside the loop.
