从多项选择中获得的价值很少

Question

我为用户提供了多种输入选择。我希望用户选择两个选项，我希望将选项存储在num1和num2中：

#include<iostream>

using namespace std;

int main()
{
    cout<<"This programme will calculate the profit and loss "<<endl;

    int num1,num2;
    cout<<"What are the given terms "<<'\n'
        <<"Please enter any two known terms to find the other remaining unknown terms"<<endl;
    cout<<" Cost price:-"<<endl;
    cout<<" selling price"<<endl;
    cout<<" profit "<<endl;
    cout<<"profit percentage "<<endl;
    cout<<" loss "<<endl;
    cout<<" losspercentage "<<endl;
    // i want to store any of the two values in num1 and num2;
}

Answer 1

要选择两个选项，现在创建num1和num2：

    cin>>num1;
    cin>>num2;

您可以使用fstream文件并输入

将其存储在文件中

    ofstream file;
     file.open ("report.txt", ios::app);
