Q:
#define clrscr() 100
main()
{
clrscr();
printf( "%dn", clrscr() );
}
Answer & Explanation
Answer: A) 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 :
main ()
{
100;
printf("%d\n",100);
}
Note: 100; is an executable statement but with no action. So it doesn't give any problem.
