Hi all,
MY first post :)

Am not sure why am getting the following errors.The program seems fine..

Quote
C:\Users\Ryuzaki!.Vegeta-PC.000\Desktop\Programs\Lab\FunAndSwiCase.c(18): error #2168: Operands of '=' have incompatible types 'int __cdecl function(int, int)' and 'int'.
C:\Users\Ryuzaki!.Vegeta-PC.000\Desktop\Programs\Lab\FunAndSwiCase.c(18): error #2088: Lvalue required.
C:\Users\Ryuzaki!.Vegeta-PC.000\Desktop\Programs\Lab\FunAndSwiCase.c(19): error #2060: Invalid return type; expected 'int' but found 'int __cdecl (*)(int, int)'.

Heres the code:

Code Select


#include<stdio.h>

int sum(int  ,int  );

int main(void)
{

    int a,b,result;
    printf("Enter two numbers\n");
    scanf("%d%d",&a,&b);
    result=sum(a,b);
    printf("The result of the two is %d\n",result);
	return 0;
}

int sum(int x,int y)
{
	sum=x+y;
	return(sum);
}

Code Select


int sum(int x,int y)
{
   sum=x+y;
   return(sum);
}

You cannot use the function name as a variable, it is a function of type int _cdecl sum

This will work...

Code Select

 
 int sum(int x,int y)
{
   int ret;
 
   ret = x+y;
   return ret;
}

As a rule you should not create variables execpt when you need them so...
You can do this...

Code Select

 
 int sum(int x,int y)
{
   return x+y;
}
