The output of the code below is
void main()
{
int k = m();
printf("%d", k);
}
void m()
{
printf("hello");
}
Answer: A
Correct answer: Error
m is defined after main and not declared before it, so at the call the compiler either rejects it outright or, under the old rules, assumes int m() - and the later definition as void m() then conflicts with that assumption. Either way the program does not compile. Assigning the result of a void function to an int would be an error in its own right.
