The group of characters are stored together in a character array.This character array is known as strings.
Each character occupies 1 byte of memory and the last character of the string is always \0.
‘\0’ is called a null character.
The terminating null (‘\0’) is important, because it is the only way the functions that work with a string can know where the string ends.
C inserts the null character automatically.
We can simply initialize a string and print its elements using a while loop.
