Control flow

Remember, you start loop from 0 and check condition by N if you use < Boolean expression. So it’s canonical to write some like this:

Control flow in loop

int i = 0;
int N = 10; // easly readable bounday condition
 
while (i < N) {  // we use <, not <= to execute N times instead of N+1
                 // and it's easy imagine like I need iterate N times
    // do something
    i++;
}
