Array Indexing

Array indexes select one stored element, starting from zero.

#include <stdio.h>

int main(void) {
    int scores[3] = {10, 20, 30};
    int index = ;
    int value = scores[index];

    printf("score=%d\n", value);
    return 0;
}

zero-based index The first array element is at index `0`, the second at index `1`, and so on.

element access `scores[index]` reads the element stored at that position.
