Data type means the type of data that a variable/constant can hold. The type of operations that can be performed on a variable/constant also depend on it's data type. For example, Data type `int` indicates that the variable/constant can hold integer value. You can perform arithmetic operations on int. It's one of the primitive data type in C. Some examples of non-primitive data types will be stack, queue, tree. In case of stack you can perform operations like pop(), push(), size(). I'll suggest you to search on internet for better definitions and examples.
