Loops and Errors

Loops can be written as while loops, do-while loops, and for loops.

while loops iterate until a condition is met.

while (a < 10) {
  a++;
}

do-while loops are while loops that initially execute the body once before checking the condition.

do {
  printf("not true!");
} (while 2 == 3);

for loops complete a set number of iterations before meeting a condition.

for (int i = 0; i <= 10; i++) {
  printf("Hello!");
}

All loops can utilize keywords like continue and break. continue restarts the loop and break breaks out of (or ends) the loop.

A for loop can always be re-written as a while loop; most while loops can be re-written as a for loop.
