Considering this, what is the use of NULL character?
A null character is a character with all its bits set to zero. Therefore, it has a numeric value of zero and can be used to represent the end of a string of characters, such as a word or phrase. This helps programmers determine the length of strings.
Likewise, how do you type a null character? On some keyboards, one can enter a null character by holding down Ctrl and pressing @ (on US layouts just Ctrl + 2 will often work, there is no need for ⇧ Shift to get the @ sign). In documentation, the null character is sometimes represented as a single-em-width symbol containing the letters "NUL".

The simpler versions of the built-in string manipulation functions in C require that your string is null-terminated(or ends with 0 ).
What is a null string in C?
In computer programming, a null-terminated string is a character string stored as an array containing the characters and terminated with a null character ( '' , called NUL in ASCII). The length of a C string is found by searching for the (first) NUL byte.
