hey Suraj Airi when scan takes input from scanf() then it will not consume your space or newline character , so it is used by gets() ! simple solution is to put one extra getchar() after scanf() ! HOPE THIS HELP YOU BETTER !

gets() has been deprecated from the standards because of it dangerous behaviour of overflowing buffer. You can also see your compiler telling you the same in form of a warning. If you are looking for an alternative then you can use fgets() instead

Suraj Airi Nope. The code was exactly the same. The question was the same. I wrote almost the same thing Arsenic has said, and gave links to the fgets() and scanf() functions. Never mind though, I was just curious why you deleted that one.

XXX it is better to use getchar () After scanf with gets() as Thirt13n said

Suraj Airi nope it isn't, and even compier is warning you about the same. gets() only knows from where to start writting in your memory and don't know where to end as soon as user enters input of size greater than your buffer size ( 10 in your case ), your program will start showing undefined behaviour which can be anything from crashing your program with segmentation fault or worse, overwriting data in a memory location where it shouldn't, corrupting data which was already present there.
