Array

#include <stdio.h>
int main() {
    int a, x[] = { 0, 1, 2, 3 }, b = 0;
    printf("addr(a) = %u\naddr(x) = %u\naddr(b) = %u\n", &a, x, &b);
    printf("distance(&a - x) = %d\n", &a - x);
    for (a = 0; a < 4; a++) {
        b = b + x[a];
        x[a] = b;
    }
    for (a = 0; a < 4; a++) {
        printf("x[%d] = %d\n", a, x[a]);
    }
    return 0;
}
