Can anyone tell me the what's the use of getchar() and gets() ? In simple explanation please. I'm a beginner .

Answer 1

..getchar reads one character like 'x'
...gets reads multiple characters like 'abc'

You need this if you want to get input from a user.

Answer 2

Don't forget that 'gets' is deprecated because of security issues (so don't use it).
