Condition To Print “HelloWord”

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();
}
