./compare 27 13 15

Find the smallest and largest numbers, which you can do either by allocating an array and converting the strings to numbers or by converting them as you do the comparison. Then output the result. For example:

The smallest integer was: 13

The largest integer was: 27

Answer 1

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
    int min = 0, max = 0, i, n;
    for (i = 1; i < argc; ++i) {
        n = atoi(argv[i]);
        if (i == 1) {
            min = n;
            max = n;
        }
        if (n > max)
            max = n;
        if (n < min)
            min = n;
    }
    printf("The smallest integer was: %d\n", min);
    printf("The largest integer was: %d\n", max);
    return 0;
}
