What will be the output?
double var = 8;
int main()
{
int var = 5;
printf("%d", var);
}
Answer: A
Correct answer: 5
The local int var = 5; shadows the file-scope double var = 8; throughout main, so %d is matched with an int and prints 5. Shadowing is legal - the two are different objects in different scopes.
