My error reads: Error 2 error C2660: 'calcAverage' : function does not take 5 arguments
It shows in lines 18 and 26, but I am not sure what exactly is wrong with it. May someone help explain this to me?
You declare this :
void calcAverage(double );
instead of :
void calcAverage(int num1, int num2, int num3, int num4, int num5)
You say to the compilator : "I am going to make a function with name calcAverage that will take 1 argument" and then implement a function calcAverage with 5 argument, so he throw an error.
void calcAverage(double );
Here you declare your function calcAverage
to take one argument of type double
but then you try calling it like:
calcAverage(num1, num2, num3, num4, num5);
You're function definition at the bottom of the file is taking 5 integers like you wanted, the problem is that the c++ compiler scans the file from top to bottom. That means when it gets to the part where you're trying to call calcAverage
with 5 arguments it only saw the function declaration at the top of the file taking a single argument, it didn't even see the definition of it yet.
To fix it simply change the declaration to take the same arguments like your definition:
void calcAverage(double );
to:
void calcAverage(int num1, int num2, int num3, int num4, int num5);
at the top of the file.
