What is the output of the following code?
main()
{
show();
}
void show()
{
printf("I'm the greatest");
}

A.	I'm the greatest	B.	Compiler error: Type mismatch in re-declaration of show.
C.	null	D.	None of these

Answer and Explanation

Answer:Compiler error: Type mismatch in re-declaration of show.

Explanation:
When the compiler sees the function show it doesn't know anything about it. So the default return type (i.e. int) is assumed. But when compiler sees the actual definition of show mismatch occurs since it is declared as void. Hence it gives compiler error.
