Here we will see, what are the basic differences between fundamental data types and derived datatypes in C or C++.
| Fundamental Datatypes | Derived Datatypes |
|---|---|
| The fundamental datatypes are also known as primitive datatypes. | Derived datatypes are composed of fundamental datatypes. |
| Some fundamental datatypes are int, char, float, void etc. | Derived datatypes are arrays, structures, pointers etc. |
| Integer or Character datatypes are classified as int, char, signed int, singned char, unsigned int, unsigned char | Pointers are used to store address of some other variables. |
| Integers are used to store integer type data, not the floating point number. | Arrays are used to store homogeneous data. |
| Floats are used to store decimal numbers. The variations are float, double, long double. | Structures are group of some primitive datatypes like int, float, double etc. |
| Void is used where no return values are specified | Unions are like structures, but all members of the union share the same memory locations. |
