any ideas???:?:

:?: can anyone tell me where the error is?

#include<iostream.h>
#include<conio.h>

void main()
{
 clrscr();
void zero_small(int &,int &);
int a,b;


cout<<"\n\n\n\tEnter the first no  ";
cin>>a;
cout<< "\n\n\n\tEnter the second no  ";
cin>>b;

 zero_small(a,b);
cout<<"\n\n\n\tValue of the first no is "<<a;
cout<<"\n\n\n\tValue of the second no is  "<<b;
getch();
}


void  zero_small(int& a,int &b  )
{
 if (a<b)
  {a==0;  }
else b==0;

return;
}

> can anyone tell me where the error is?
Erm, maybe your logic amongst other things?

I mean what were you expecting the function to do:

void  zero_small ( int& a, int &b  )
{
   if ( a < b )
   {
      a == 0;
   }
   else b == 0;

   return;
}

i wanted to print the smaller no as 0..thatz why i did that..is that wrong?

Well why do you have a return in the function, you shouldn't need one because you are passing back by reference.

You don't use the double equal sign if you are setting a value to a variable.

This is how I might do it.

#include <iostream.h>

void zero_small ( int &a, int &b )
{
  if ( a < b )
  {
    a = 0; //one equal sign not double!
  }
  else b = 0;
 //no returns
}

int main()
{
  int a;
  int b;

  cout << "\n\n\n\tEnter the first no  ";
  cin >> a;
  cout << "\n\n\n\tEnter the second no  ";
  cin >> b; 
  zero_small ( a, b );

  cout << "\n\n\n\tValue of the first no is " << a;
  cout << "\n\n\n\tValue of the second no is  " << b;

  getchar();
  getchar();
  return 0;
}

I agree with iamthwee. There seems no point in that segment of code! It checks a relation: if a is equal to zero or not, if a is less than b, otherwise it relates b to 0, which is pointless.

Is the code meant to say, check a==(some integer) and then print a=some expression, in the case that a<b, or something?

Or - you are trying to assign a or b to 0, in which case it would be a=0 or b=0, not the relational operator ==.

EDIT//oops! sorry for posting this, i think the top two posts were posted as i was writing this!

Wait, I'm not sure if he edited the code in the first post, but the function just had return; , not return someVal; . It's not neccesary to include the return; statement at the end of a void function, but I sometimes put it just so I'm controlling when the function returns, not the end curly bracket. Is that considered "wrong" or weird?

>Is that considered "wrong" or weird?
Falling off the end of a function automatically returns, so it's weird in that people don't expect to see that kind of redundancy in well written code. It's not wrong though.

thank u !!...i got de point!!
