[SOLVED] MarketingSimulator

Question

I am making a marketing simulator for a course I am doing, they have provided a code challenge with a little example code that works well in the main.cpp, however when I add it to the implementation of the class I get errors:

Severity Code Description Project File Line Suppression State
Error (active) E0109 expression preceding parentheses of apparent call must have (pointer-to-) function type Merkelex C:\Users\c\source\repos\something\something\something.cpp 88

Severity Code Description Project File Line Suppression State
Error C2064 term does not evaluate to a function taking 0 arguments Something C:\Users\c\source\repos\something\something\something.cpp 90

My question is why am I receiving this error and how would I solve it?

Answer 1

The problem is that you attempt to call a member function through a pointer-to-member-function without supplying the object to call the function from. The syntax for this is somewhat unique:

For example, if you want to use the current object (i.e. the one processOption() is currently called from), you could write:

(this->*menu[userOption])();

Your code is too long for the description and therefore truncated. Please paste it into a playground project and link that here instead:
