【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
#include
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！
