case aSTRING:

break;
}

— This is an function with the return type of a structure i created
— The parameter is a typedef to a function
— Pointer
— It calls that function and stores what that function returns which is an enumeration symbol i created , either aSTRING or INTEGAR
— Based on those options, it will print one of two statements
— Then it scanf for a variable called ArrayMemberTotal , if you put in an int like 2 , 4 , or something like that it works fine
— But lets say there is an error on the user end, i want it to print a timed error message(i have a function that does that ) then re ask the qestions until and scan again
— I tryed goto and it doesnt do what i am trying to do
— Goto statement is only useful and must only be used for cleanup and not for retry
— So in this case what would be a good way to deal with this issue
