【C++】买鸡问题

公鸡5元1只，母鸡3元1只，小鸡1元3只，花了100元钱买100只鸡，问公鸡、母鸡、小鸡各多少只？

 #include<iostream>

#include<stdio.h>

using namespace std;

//公鸡5元1只，母鸡3元1只，小鸡1元3只，花了100元钱买100只鸡，问公鸡、母鸡、小鸡各多少只？

int main()

{

    for (int i = 1; i <= 100; i++) {

        for (int j = 1; j <= 100; j++) {

             for (int k = 1; k <= 100; k++) {

                 if (5 * i + 3 * j + 1 / 3 * k == 100 && i + j + k == 100) {

                     cout << "公鸡有" << i << "只" << endl;

                     cout << "母鸡有" << j << "只" << endl;

                     cout << "小鸡有" << k << "只" << endl;

                     cout << endl;

                 }

             }

        }

    }

}

采用穷举法，for循环的嵌套即可！
