C-String: In C++, a declaration of an array of “char” is usually referred as “C-string”. But an array of “char” is not a C-string by itself. An effective C-string needs an occurrence of a terminating null character “\0”. No header file is required to make a C-string because “char” is a built-in data type. Therefore, “<cstring>” file contains several functions that work on C-string. Example: Consider the below definition of C-string: //Store the student name with 10 characters char student_name[10]; Here the data type “char” is defined first and it is followed by the variable name “student_name”. The “[10]” is referred as “size declarator”. It indicates how many characters it can hold in memory cells.

C-String:

In C++, a declaration of an array of “char” is usually referred as “C-string”. But an array of “char” is not a C-string by itself.

An effective C-string needs an occurrence of a terminating null character “\0”.

No header file is required to make a C-string because “char” is a built-in data type. Therefore, “<cstring>” file contains several functions that work on C-string.

Example:

Consider the below definition of C-string:

//Store the student name with 10 characters

char student_name[10];

Here the data type “char” is defined first and it is followed by the variable name “student_name”.

The “[10]” is referred as “size declarator”. It indicates how many characters it can hold in memory cells.
