Is my function defition right?

Hello,
I needed to create a function definition so that in returns the greatest of the two input parameters.

This is what I have. I think it is right. The first two paramenter receive data from the user than the last one returns an parameter.

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
 
Max (int num1, int num2, int& greatest);
{ cout << “Enter in two different integers:” << endl;
cin >> num1 >> num2;

if  
num1 > num2;
num1==greatest;
cout << num1;


else if
num2 > num1;
num2==greatest;
cout<<num2;

}

No.
Try this:
1
2
3
4
5
6
7
8
9
10
11
 
int Max(){ //no semicolon in the definition
int num1, num2; //these don't need to be parameters

cout << "Enter 2 numbers: ";
cin >> num1 >> num2;

if (num1>num2)
return num1;

else
return num2;}


The function here gets 2 numbers, then returns the larger.

Just want to make sure I understand.

I don't have to include greatest, but it would be still output?

What do you mean by "output"?

Do you understand the idea of returned values from functions?

correct. You can treat max like an int pretty much.
Like this:
1
2
3
4
5
6
7
 
int main(){
    int greatest = Max(); //it will get 2 numbers and return the larger, then greatest is set to the 
                                     //return value of Max
    /*
    more code...
    */
    return 0;}
