#include <bits/stdc++.h>
using namespace std;
int main() {
 int m, n;
    cin >> m >> n;
    int c;
    if(m % n == 0)
        c = m / n;
    else
        c = m / n + 1;
    cout << c;
    return 0;
}
    

你是不是不会做

#include using namespace std;

int main() { int a, b, c, d; cin >> a >> b; c = a % b; if (c != 0) d = a / b + 1; else d = a / b; cout << d; return 0; }
