ABC三只小猪称重的代码怎么写

可以使用以下两种方法来编写ABC三只小猪称重的代码：

方法一：使用if嵌套语句

#include <iostream>
using namespace std;

int main() {
    int a, b, c;
    cout << "请输入小猪A的体重：";
    cin >> a;
    cout << "请输入小猪B的体重：";
    cin >> b;
    cout << "请输入小猪C的体重：";
    cin >> c;
    if (a >= b && a >= c) {
        cout << "小猪A最重" << endl;
        if (b >= c) {
            cout << "小猪B次重，小猪C最轻" << endl;
        } else {
            cout << "小猪C次重，小猪B最轻" << endl;
        }
    } else if (b >= a && b >= c) {
        cout << "小猪B最重" << endl;
        if (a >= c) {
            cout << "小猪A次重，小猪C最轻" << endl;
        } else {
            cout << "小猪C次重，小猪A最轻" << endl;
        }
    } else {
        cout << "小猪C最重" << endl;
        if (a >= b) {
            cout << "小猪A次重，小猪B最轻" << endl;
        } else {
            cout << "小猪B次重，小猪A最轻" << endl;
        }
    }
    return 0;
}

方法二：使用三目运算符

#include <iostream>
using namespace std;

int main() {
    int a, b, c;
    cout << "请输入小猪A的体重：";
    cin >> a;
    cout << "请输入小猪B的体重：";
    cin >> b;
    cout << "请输入小猪C的体重：";
    cin >> c;
    int max = (a > b ? (a > c ? a : c) : (b > c ? b : c));
    int min = (a < b ? (a < c ? a : c) : (b < c ? b : c));
    int mid = a + b + c - max - min;
    cout << "小猪" << (max == a ? "A" : (max == b ? "B" : "C")) << "最重" << endl;
    cout << "小猪" << (mid == a ? "A" : (mid == b ? "B" : "C")) << "次重" << endl;
    cout << "小猪" << (min == a ? "A" : (min == b ? "B" : "C")) << "最轻" << endl;
    return 0;
}
