#include "stdio.h"

int main() {
  int i;
  //The first part of this for loop is run once as an initialization
  //the second part is checked for truth at the end of each execution to determine if the loop should be run again
  //the third part is executed at the end of the loop (typically used to increment something)
  for (i = 0; i < 5; i++){
    printf("i = %d\n", i);
  }
  return 0;
