simple illustration of why C is awesome once you understand it

array.c

#include <stdio.h>

int main() {
  int a[10];

  int i;
  for (i=0; i < 10; i++) {
    a[i] = i;
  }

  // Simple intro to C trivia: what does the if statement below print? foo or bar?
  if (a[1] == 1[a]) {
    printf("foo!\n");
  } else {
    printf("bar\n");
  }
  return 0;
}
