What are strings and its types?

A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers.

A string is a collection of characters that ends with the null character \0 in C programming. By default, the compiler appends a null character \0 to the end of a sequence of characters wrapped in double quotation marks.

What is string and structure in C?

In C programming, a string is a sequence of characters terminated with a null character \0 . For example: char c[] = "c string"; When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character \0 at the end by default.

What is not a string?

Is string a class?

What is a string value?

A StringValue is an object whose purpose is to store a single Lua string. The length of the string can't be more than 200,000 characters (this will cause a “String too long” error). Like all “-Value” objects, this single value is stored in the Value property.

Is string a data type or class?
