Question

In C. Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the element. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}.

Answer 1

#include <stdio.h>

int main() {
    const int SCORES_SIZE = 4;
    int lowerScores[SCORES_SIZE];
    int i;

    lowerScores[0] = 5;
    lowerScores[1] = 0;
    lowerScores[2] = 2;
    lowerScores[3] = -3;

    for (i = 0; i < SCORES_SIZE; ++i) {
        if (lowerScores[i] > 0) {
            lowerScores[i]--;
        } else {
            lowerScores[i] = 0;
        }
    }

    for (i = 0; i < SCORES_SIZE; ++i) {
        printf("%d ", lowerScores[i]);
    }
    printf("\n");
    return 0;
}

#include <stdio.h>

int main() {
    const int SCORES_SIZE = 4;
    int lowerScores[SCORES_SIZE];
    int i;

    for (i = 0; i < SCORES_SIZE; ++i) {
        scanf("%d", &lowerScores[i]);
    }

    for (i = 0; i < SCORES_SIZE; ++i) {
        if (lowerScores[i] > 0) {
            lowerScores[i]--;
        } else {
            lowerScores[i] = 0;
        }
    }

    for (i = 0; i < SCORES_SIZE; ++i) {
        printf("%d ", lowerScores[i]);
    }
    printf("\n");
    return 0;
