#include <iostream>
int add(int first,int second)
{
    std::cout<<"in add (),received"<<first<<" and"
        <<second<<"\n";
    return (first+second);
}




int main()
{
    using std::cout;
    using std::cin;
    cout<<"i'm in main()!\n";
    int a,b,c;
        cout<<"enter two numbers:3 5 ";

    cin>>a;
    cin>>b;
    cout<<"\ncalling add()\n";
    c=add(a,b);
    cout<<"\nback in main().\n";
    cout<<"c was set to"<<c;
    cout<<"excting...\n\n";
    return 0;
}


怎样最后输出是下面这个样子、
输出：
i'm in main ()
enter two number : 3 5

calling add()
in add(),receviced 3 and 5

back in main() .
c was set to 8
excting...
