You define b but this is not to use b, so prompt warning, need pay attention to the assignment here not use
Such as your program only
Int main () {
Int a=5;//only that assignment can also warn a not used, so the assignment is not used, the same, you b array in the same way, so prompt warning
return 0;
}
