Mar 28th, 2007

main()
{
if( ? )
{
printf("welcome");
}
else
{
printf("to ieg");
}
}
-----------------------------------------------------------------------
Output should be

any conditional statement that is either true or false. for example if you were asked to enter either 'Y' or 'N' (Yes or No) then the statement might read

if( answer == 'Y')
{
   // true statement
}
else
{
   // false statement
}

Thisnk it's a trick question. May be you didn't read it fully..

@mohiuddin.shaik
It is allowed to write/change anything other than ? e.g. can I use a goto inside the if block?

you are right -- I didn't read the expected outcome, which is impossible. There is no solution that will give that outcome.

What abt GOTO LABEL?

 Help with Code Tags 
 c Syntax (Toggle Plain Text) 
if ( true )
{
     cout << "Hi" << endl ;
     goto ELSE_PART ;
}
else
{
ELSE_PART:
     cout << " There" << endl ;
}
if ( true )
{
     cout << "Hi" << endl ;
     goto ELSE_PART ;
}
else
{
ELSE_PART:
     cout << " There" << endl ;
}

of course that's cheating but then teh question is not fair..

You have just gone out to show one of the horrors of using the GOTO statement in C/C++...

"I don't accept change. I don't deserve to live."

"Working a real job is a win if you're lazy, greedy, or unmotivated. If you're average, you fit right in. And if you're above average, the basic terms of employment and premise of the arrangement is against your interests."

void main'ers are DOOMed

Seems simple enough

int main()
{
    if (!printf("welcome ")) {
        printf("welcome");
    } else {
        printf("to ieg");
    }
    return 0;
}

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
Do not PM me for help; You'll be ignored, or told to learn to read.
Do not ask me if I'm muslim - I'm not. Nor do I care about yours or anyone else's mysticism. Religion is a matrix, take the RED PILL.
