Simple C code

Write a function: fun(int n)
which takes only 1 or 0 as input and returns 0 and 1 respectively.

You have to use only arithmetic operators.

Well here is another way to get this...

int fun(int x){
x = (x+1)%2 ;
}

int fun(int n)
{
n?return 0:return 1;
}

well your logic is correct but its syntactically wrong.

int fun(int n)
{
n?return 0:return 1; // this is not possible...u will get a compilation error..
}

Correct usage:

int fun(int n)
{
return n?0:1 ;
}

int fun(int x)
{
return 1-x ;
}
