Datatype classes in c
WebA data type, in programming, is a classification that specifies which type of value a variable has and what type of mathematical, relational or logical operations can be applied to it without causing an error.

WebHere are three different data types in C++ which are given below: 1. Primitive Data Types These are pre-defined in c++, also called the built-in data types. We can directly use them to declare the variables. a. Integer: Usually defined by “int”. We can know the size of memory allocated and how the variable is declared as below. Code: WebC does not have its own String data type like Java. Only we can declare String datatype in C using character array or character pointer For example : char message [10]; or char *message; But you need to declare at least: char message [14]; to copy "Hello, world!" into message variable. 13 : length of the "Hello, world!"
