illegal call of non-static member function

Can anyone figure out why I get -9.032654e something from my biWeeklySalary function?

Only one of those loops correctly accesses all the elements of your array.

One of them steps off the end, no doubt trashing something else into the bargain.

for ( i = 0 ; i < N ; i++ )
No need for <=
No need to subtract one from the size of the array.

I fixed the loop which stepped of the array and am still getting -9.25596e+061 for all calculation of biWeeklySalary

Correct me if i am wrong, but at different places you access and modify the array "hour" in different ways, please be consistent wiht your style and use the correct form of loop control variable to avoid subtle bugs. The would be problem areas have been marked by me in red.

If problem persists, repost.

Hope it helped, bye.

[SHWOO]

Those three loops have been fixed and I have instantiated two objects with different values for hours in the array yet, both calls to biWeeklySalary with two different objects show the same -9....e+061 value

[~s.o.s~]

If posssible please post your int main () function so i can analyse the problem completely.

Thanks.

> double totalPay;
This is in the class, as a private member variable

> double totalPay = 0;
This is in a function - it hides your class variable.

Which compiler are you using?
