What really means by word "C-string" in C / C++? Pointer to char? Array of characters? Or maybe const-pointer / const array of characters?

String in C programming is a sequence of characters terminated with a null character '\0'. Strings are defined as an array of characters. The difference between a character array and a string is the string is terminated with a unique character '\0'.
'C' language does not directly support string as a data type. Hence, to display a String in C, you need to make use of a character array. The general syntax for declaring a variable as a String in C is as follows, char string_variable_name [array_size];
Strings are used for storing text/characters. For example, "Hello World" is a string of characters. Unlike many other programming languages, C does not have a String type to easily create string variables.
1. A string is any series of characters that are interpreted literally by a script. For example, "hello world" and "LKJH019283" are both examples of strings. In computer programming, a string is attached to a variable as shown in the example below.
A "C string" is an array of characters that ends with a 0 (null character) byte. The array, not any pointer, is the string. Thus, any terminal subarray of a C string is also a C string. Pointers of type char * (or const char *, etc.) are often thought of as pointers to strings, but they're actually pointers to an element of a string, usually treated as a pointer to the initial element of a string.
