Question: if "condition"
printf("Hello");
else
printf("World")

what should be the condition,
so the output will be HelloWorld.

Answer: if(!printf("hello"))
printf("hello");
else
printf("world");

if(!printf("hello"))
printf("hello");
else
printf("world"); Source: CoolInterview.com

if(!printf("hello"))
printf("hello");
else
printf("world"); Source: CoolInterview.com

second answer is wrong.
modified program is
#include<stdio.h>
main()
{
if(printf("hello")!=0)
printf("world");
else
printf("world");
} Source: CoolInterview.com

second answer is wrong.

second and third are wrong
The right answer is

{
if(printf("hello")!=5)
printf("hello");
else
printf("world");
} Source: CoolInterview.com

#include<stdio.h>
main()
{
if(printf("hello")==0)
printf("hello");
else
printf("world");
} Source: CoolInterview.com

both the posts are wrong ...
u cannot change the question
my friend....
here is the answer....having 4yers of c experiance....take it


#include<stdio.h>
int main()
{
if( printf("hello")-5 )
printf("hello");
else
printf("world");
}
as printf returns number of characters it has printed it will return 5 and minius 5 we get 0 ..it will not enter the if condition but hello will be printed and obvious it goes to else part and world is printed Source: CoolInterview.com

#include<stdio.h>
main()
{
if(printf("hello")==0)
printf("hello");
else
printf("world");
} Source: CoolInterview.com

#include<stdio.h>
main()
{
if(printf("hello") && 0)
printf("hello");
else
printf("world");
} Source: CoolInterview.com

main()
{
clrscr();
if(printf(“Hello “) == 0)
printf(“Hello”);
else
printf(“World”);
getch();
}
Source: CoolInterview.com

main()
{
if(printf("hello")==0)
printf("hello");
else
printf("world");
} Source: CoolInterview.com

in linux answer is
if(!fork())
{
printf("hello");
}
else
{
printf("world
");
} Source: CoolInterview.com

if(!fork())
{
printf("hello");
}
else
{
printf("world");
} Source: CoolInterview.com

THIS IS CORRECT ANSWER.....


#include<stdio.h>
main()
{
if(printf("hello")!=0)
printf("world");
else
printf("world");
} Source: CoolInterview.com

In 3 rd Question he changed Question itself..so wrong

correct one is.....>
#include<stdio.h>
#include<conio.h>
main()
{
if(printf("hello")==0)
printf("hello");
else
printf("world");
getch();
} Source: CoolInterview.com

#include<stdio.h>
main()
{
if(printf("Hello")==0)
printf("Hello");
else
printf("World");
} Source: CoolInterview.com

Second answer is perfect.

#include<stdio.h>
main()
{
if(printf("hello")!=0)
printf("hello");
else
printf("world");
}

While checking for if condition, "hello" gets printed. And As if condition is evaluated as False, "World" gets printed. As a result the output is "helloworld" Source: CoolInterview.com

#include<stdlib.h>
#include<stdio.h>
#include <unistd.h>
int main()
{
pid_t pid;
pid = fork();
if(pid !=0 )
printf("hello");
else
printf("world");
} Source: CoolInterview.com

void main()
{
clrscr();
if(printf("HELLO ")==0)
{
printf("hello");
}
else
{
printf("WORLD");
}
getch();
}

I thnk it works......

printf("Hello");
else
printf("World");
