what is void data type
Void is an empty data type normally used as a return type in C/C++, C#, Java functions/methods to declare that no value will be return by the function.
The another used of void is to declare the pointer in C/C++ where It is not sure what data type is addressed by the pointer.
eg:
void *p;
Here p can hold the address of int or float or char or long int or double.
1)Built-in data types
Fundamental data types (int, char, double, float, void, pointer)
Derived data types (array, string, structure)
2)Programmer-defined data types
Structure
Union
Enumeration
programmer defined data types also called as user defined data types
