Each element is a pointer to a string literal.

Solution explanation

#include <stdio.h>

int main() {
    char *months[12];
    months[0] = "January"; months[1] = "February"; months[2] = "March";
    months[3] = "April"; months[4] = "May"; months[5] = "June";
    months[6] = "July"; months[7] = "August"; months[8] = "September";
    months[9] = "October"; months[10] = "November"; months[11] = "December";
    int n, m;
    scanf("%d", &n);
    for (int i = 0; i < n; i++) {
        scanf("%d", &m);
        if (m >= 1 && m <= 12) printf("%s\n", months[m - 1]);
        else printf("invalid\n");
    }
    return 0;
}
