Hello, I made a program that worked perfectly on one of my pcs. When I moved it to another computer I am getting an error now stating that I need to include a pointer on my fmin and fmax functions. I'ts somewhat lengthy but I want to know if maybe te requirement for the pointer might be because of something else in my code. If you can explain why I need to use pointers only for fmin and fmax if its necessary that would be great.
calc.h

class calc
{
private:
int Size;
float sum;
int x;
float mAx;
float mIn;
float mult;
float var;
float stdev;
float sub;
float valArr[100];
float avg;
public:
calc();
void calculations();
void outputs();
bool cont(char choice);
void difference();
float fmax(float valArr[],int Size);
float fmin(float valArr[],int Size);
};

error:
calc::fmin': function call missing argument list; use '&calc::fmin' to create a pointer to member
and when I try that this pops up:
'float &calc::fmax(float [],int)' : overloaded function differs only by return type from 'float calc::fmax(float [],int)'
1>calc.h(22) : see declaration of 'calc::fmax'
calc.cpp(39): error C2040: 'calc::fmax' : 'float &(float [],int)' differs in levels of indirection from 'float (float [],int)'
Again thank you for taking time to read.
