Can we use function on left side of an expression in C and C++?


In C, it might not be possible to have function names on left side of an expression, but it’s possible in C++.


using namespace std;

/* such a function will not be safe if x is non static variable of it */
int &fun()
   static int x; 
   return x;

int main()
   fun() = 10;

   /* this line prints 10 on screen */
   printf(" %d ", fun());

   return 0;
