Discussion Forum : C Preprocessor
Question -
Determine output:
#include
#define clrscr() 100
void main()
{
clrscr();
printf("%dn", clrscr());
}
#include
#define clrscr() 100
void main()
{
clrscr();
printf("%dn", clrscr());
}
Answer: Option C
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\n", 100);
}
