尝试添加分数，同时还打印LCD

Question

我是一个初学者，试图找出这个添加分数的程序，同时也让他们的输出打印出结果中的最低公分母形式。以这种形式运行它永远不会正常运行...

using namespace std;

class Fraction { //Creates class Fraction
private: //Makes data members private
    int num;
    int denm;
};

int main()
{
    int num;
    int denm;
    int num2;
    int denm2;
    int plus;
    int plus2;

    cout << "Please enter the numerator and denominator of the first fraction: " << endl; 
    cin >> num >> denm; 
    cout << "Please enter the numerator and denominator of the second fraction: " << endl;
    cin >> num2 >> denm2;
    plus = num*denm2 + denm*num2;
    plus2 = denm*denm2;
    cout << num << "/" << denm << " + " << num2 << "/" << denm2 << " = " << plus << "/" << plus2;
    cout << "Hit 'enter' to exit..." << endl;
}

您需要以保持输出窗口打开的方式运行程序或修改它以完成此操作。请参阅此处的示例：

在任何环境中执行此操作的一种方法是在cin之前return 0另一个值 - 当然，这会要求您按下先输入的其他内容，但它会为目的
