Q. Determine Output
Code:#define clrscr() 100
void main()
{
clrscr();
printf("%d", clrscr());
}
✅ Correct Answer: (C)
100
Explanation: Preprocessor executes as a seperate pass before the execution of the compiler. So textual replacement of clrscr() to 100 occurs. The input program to compiler looks like this :
void main()
{
100;
printf("%d", 100);
}
Note: 100; is an executable statement but with no action. So it doesn't give any problem.
void main()
{
100;
printf("%d", 100);
}
