What should be the “condition” so that the following code snippet prints both HelloWorld!
if "condition" printf ("Hello"); else printf("World");
Method 1:
#include<stdio.h> int main() { if (! printf ( "Hello" )) printf ( "Hello" ); else printf ( "World" ); getchar (); } |
Explanation: Printf returns the number of character it has printed successfully. So, following solutions will also work
if (printf(“Hello”) < 0) or if (printf("Hello") < 1) etc
Method 2: Using fork()
#include<stdio.h> #include<unistd.h> int main() { if (fork()) printf ( "Hello" ); else printf ( "World" ); getchar (); } |
This method is contributed by Aravind Alapati.
Please comment if you find more solutions of this.
