There is no need to contact me directly :-)
NSString variables are pointers (which can be seen by noticing *). Pointers are integers specifying address in memory where something is stored. You can have same strings stored on different locations in memory. Comparing pointers compares the addresses, not the contents. Regards,
Ivan Vučica via phone Thank you . There was little mistake in the attached code that you spotted i .e while(word2!=Quit) so sorry for that. But still i am not getting that why it is not working without using isEqualToStrind method

Also, don't forget you can get a constant string instance like this: @"Quit"
So:
while(![@"Quit" isEqualToString:word2])
or while(![word2 isEqualToString:@"Quit"])Regards,

You can't compare strings with "==", use "while([Quit isEqualToString: word2] == NO)" instead. In order for that to work, you'll need to setup word2 before comparing it, too. So either set it to nil first or use a do-while loop (probably what you want here, anyway).
