• 多组读取语法：temp = scanf("%d %d %d", &n, &h, &m)
• 余数大于0，加1

#include <stdio.h>

int main() {
    int n, h, m, temp;
    while ((temp = scanf("%d %d %d", &n, &h, &m)) != EOF) {
//         temp = scanf("%d %d %d", &n, &h, &m);
        if ((m % h) > 0) {
            printf("%d\n", n - (m / h + 1));
        } else {
            printf("%d\n", n - (m / h));
        }
    }

    return 0;
}
