String Handling in C programming with common functions
The string can be initialized
char languageName[20]="cprogramming";
char languageName[ ] ="cprogramming";
The most common string function are:
- String is a combination of characters and it is enclosed in double quotes
- Character array is used to hold string.

- fputs( )
- fgets( )
- strcpy( )
