Why do link those extra link in question?
Please remove and include only required links for question..

About question, I just want say, please revise the topic of how functions are called and how to get back results...
Your sum or product variable are not related to function..
call like this:
cout<<"Sum is" <<operations(a, b, calc) ;
In function, depending on calc variable return sun or product...
Hoping you can do further..
