help ASAP w/program

**CindyLou** · 02-25-2002

Need program to output largest number of two. The main function must remain as is. I believe the getinput function is where the problem is. I can get program to run when I get the input from within the main function, but I can't get it to run with a separate getinput function (which unfortunately is how I am required to write it). Please help!! here is the program:

#include <iostream.h>

int getinput (int num1, int num2)
{
cout << "Enter two integers: ";
cin >> num1 >> num2;
return 0;
}

int getmax (int num1, int num2)
{
if (num1 > num2)
return num1;
else
return num2;
}

int main ()
{
int num1, num2;
getinput (num1, num2);
cout << "The bigger number is: " << getmax(num1, num2) <<endl;

return 0;
}

first: You need function definitions.

example: int getinput(int num1, int num2); < -- notice the ";"

these should be at the beginning before main, or before you use the function.

----------------------------
second, i'd move the 2 function declarations you have to after the main function

new code:

Code:

#include <iostream.h> 
// using namespace std;

void getinput (int& num1, int& num2);
// pre & post: comments

int getmax (int num1, int num2);
// pre & post: comments

int main () 
{ 
int num1 = 0, num2 = 0; 
getinput (num1, num2); 
cout << "The bigger number is: " << getmax(num1, num2) <<endl; 

return 0; 
}

void getinput(int& num1, int& num2) 
{ 
cout << "Enter two integers: "; 
cin >> num1 >> num2; 
} 

int getmax(int num1, int num2) 
{ 
if (num1 > num2) 
return num1; 
else 
return num2; 
}

Thanks, tried this (many times). My output is -858993460
I can't seem to figure this out. I used visual c++ and borland and get junk on both. Problem seems to be in getinput. Any other ideas????

ok try that one

for your first getinput function the return command can only give back 1 variable. This means the 2 inputs you have cannot be put back to main (they're local to function) using a return method. You have to use a void function and the call-by-reference parameters so that the variables are changed within the main function as well.

Sorry, haven't slept much, hope that makes remote sense

I have trouble with void functions. I did try this, but didn't work. Could you give me an example

I know you're tired, I appreciate this!!!!!

I Got it, I Got it!!! Yeah. Thanks so much. Now I can go to bed myself. Here's what I did with getinput:

void getinput (int &num1, int &num2)
{

cout << "Enter two integers: ";
cin >> num1 >> num2;

return;
}

This programming class is going to get the best of me. Goodnight!!
