Hi,I am confused and need the answer of the question mentioned below soon.
return(x,y) is valid?
Can a return() function return more than one value within one statement.
eg: - #include<stdio.h>
-
#include<iostream.h>
-
int sum(int i,int j);
-
main()
-
{
-
int a,b,k,l;
-
char c;
-
a=3,b=4;
-
k= sum(a,b);
-
l=sum(a,b);
-
printf("%d %d",k,l);
-
c= getchar();
-
return 0;
-
}
-
-
int sum(int i,int j)
-
{
-
int kk,ll;
-
kk = i + j;
-
ll = i * j;
-
return(kk,ll);
-
}
Earlier I thought compiler should give a compile time error but instead it executed the code and retun 12 12 as the answer.WHY????? ???

, is an operator, just like +, ||, ==, etc. So returning kk, ll actually returns (I think) ll, as the comma operator returns the rightmost expression. Of course, the function isn't returning both kk and ll, it is only returning 1, so there is no reason to ever use the comma operator in a return statement.

very basic and easy.
'return' returns only one variable. no more than that.
you can return an array, vector, int,long....... ..
anything but only one variable.
GOOD LUCK

at least not directly, in the C FAQ where FAQ 5.2 seems most relevant.

Hi,
If I want to call functions that don't return int without declaring
them, will there be any harm?
I only want to assign the function(return value) to the type that it
returns, so I don't see how the return value comes to play here.

hello all,
I want to create a function that returns the first element of the Array
that is input to it. However, the Input Array can be an Array of points,
double, or anyother type, which means the return type of the function depends
on the type of the objects the Input array holds.
I can have the return type as Object, but it has problems like late binding
and more importantly the client has to always Cast it. For example.
