一道循环题目发现好像没有人用map， 特水一篇题解

C++ 代码

#include <bits/stdc++.h>

using namespace std;

int n, x, ans;
char c;
map<char, int> m;

int main()
{
    scanf("%d", &n);
    while(n --)
    {
        scanf("%d %c", &x, &c);
        ans += x;
        m[c] += x;
    }
    printf("Total: %d animals\nTotal coneys: %d\nTotal rats: %d\nTotal frogs: %d\n", ans, m['C'], m['R'], m['F']);
    printf("Percentage of coneys: %.2lf %%\nPercentage of rats: %.2lf %%\nPercentage of frogs: %.2lf %%\n", 100.0 * m['C'] / ans, 100.0 * m['R'] / ans, 100.0 * m['F'] / ans);
}
