Condition To Print “HelloWorld”
What should be the “condition” so that the following code snippet prints both HelloWorld!
if "condition"
printf ("Hello");
else
printf("World");
Method 1: using logical NOT(!)
c
#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()
c
#include<stdio.h>
#include<unistd.h>
int main()
{
if (fork())
printf ("Hello");
else
printf ("World");
getchar ();
}
