Calling Functions

[ghnelson]

Hey I really need some help with studying for a Computer Science exam that's tomorrow. I know how to do loops, functions, etc but there's a section on one of our pretests that I don't really understand. If you could help me out that would be really great. I don't expect you to answer all of them but if you see a couple that you could do I would really appreciate it. Thanks you

For each of the following function prototypes, which of the calls are syntactically correct and incorrect, and a short sentence explaining why?

//Variable Declarations
int A,B,C;
float X,Y;
char Char;

//Function Prototypes
int Maximum(const int Num1,const int Num2);
void Total(const float A,const float B,float&C);
char GetChar();


1. Maximum(A,B);
2. A=Maximum(7,3);
3. A= Maximum(Num1,Num2);
4. Total(A,B,C);
5. Total(3.0,X,Y);
6. Total(3.0,5.0,8.0);
7. Total(Y,X,Y);
8. GetChar(Char);
9. Char= GetChar();

You should make the first guess.

List the ones you don't understand and explain why you don't understand them.
