c++ - 拼接问题

Question

我想获取三个用户输入值 A、B、C，然后创建一个新的整数来存储这三个值，称为容量。我希望整数用逗号分隔，但是当我输出整数容量时，它仅作为 C 的值返回。我不知道如何解决这个问题。

#include <iostream>

using namespace std;

int main()
{
    int A;
    cout <<"Enter Capacity of Jug A"<< endl;
    cin >>A;
    int B;
    cout <<"Enter Capacity of Jug B"<< endl;
    cin >>B;
    int C;
    cout <<"Enter Capacity of Jug C"<< endl;
    cin >>C;

    int capacity;
    capacity = (A, B, C);
    cout <<"capacity is "<< capacity;

    return 0;
}

Answer 1

你可以像这样使用数组:

#include <iostream>

using namespace std;

int main()
{
    int A;
    cout << "Enter Capacity of Jug A" << endl;
    cin >> A;

    int B;
    cout << "Enter Capacity of Jug B" << endl;
    cin >> B;

    int C;
    cout << "Enter Capacity of Jug C" << endl;
    cin >> C;

    int capacity[3];
    capacity[0] = A;
    capacity[1] = B;
    capacity[2] = C;

    cout << "capacity is " << capacity[0] << "," << capacity[1] << "," << capacity[2];

    return 0;
}
