Answer / susie

Answer :

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

Answer / naveen

yes it works and prints 100 because we defined clrscr() to
100. we can also set values to any predefined functions

#include"math.h" void main() { printf("Hi everybody"); } if <stdio.h> will be included then this program will must compile, but as we know that when we include a header file in "" then any system defined function find its defination from all the directrives. So is this code of segment will compile? If no then why?
