Answer 1

First problem, you didn't declare 'num2.' Just like you put 'int' in front of num1 when you declared/called your function, you'll do the same for num2.

CHANGE:
int max(int num1, num2);

TO:
int max(int num1, int num2);

Second problem, you have a semi-colon when you're calling your function, remove that and the function can execute.

CHANGE:
int max(int num1, num2);
{
}

TO:
int max(int num1, int num2)
{
}

Your corrected code is below:

#include <iostream>
using namespace std;

// function declaration

int max(int num1, int num2);
int main ()
{
int a = 100;
int b = 200;
int ret;

// calling a function to get max value.
ret = max(a,b);
cout << "max value is:" << ret << endl;

return 0;
}

// function returning the max between two numbers
int max(int num1, int num2)
{
// local variable declaration
int result;
if (num1 > num2){
result =num1;
}
else {
result = num2;
}

return result;
}
