program to find out generic root of any number on C language
generic root means:
in this we do addition of a given number until reached a single digit after addition . For example:
Generic root of 784: 7 + 8 + 4 = 19 since 19 is a two digit numbers so 1 + 9 = 10.then again add 1 +0=1
So, ge...

Strings in C language
String is a collection of characters in an array.It is terminated by by \0 (null character)
There are two ways to declare string in c language.
1)By char array
declaring string by char array is as follows:
