FIXED WITH CORRECT POSTING FORMAT, sorry.



OK, so I haven't touched C++ in about 2+ years and I have a class currently where we need to input the values from the function fish_catch into an array, and display them (this is already done and runs). I then need to run the functions I have defined below to calculate the fishers' specific pay among other things. I am getting an error trying to call the maxValue function saying (I figured I'd try one function at a time as opposed to all at once and throwing a ton of errors):



----------This is fixed
In function 'int main()':

project1.cc:57: error: expected primary-expression before "const"

project1.cc:57: error: expected primary-expression before "const"




I now have this problem:

in function 'intmain()':

project1.cc: error: 'minVal' was not declared in this scope

project1.cc: error: 'maxVal' was not declared in this scope




I'm completely lost as to why I am getting the error as I've consulted multiple books and online resources and it all looks alright to me...
