Study Notes
Primitive Data Types in C
- Examples of primitive data types include
int,char,float, anddouble. - These data types are built-in and represent single values.
Language Type
- C is a procedural programming language, emphasizing a structured and systematic approach.
- It is categorized as a high-level language due to its abstraction from machine code.
Purpose of Void
- The
voidkeyword is used to indicate that a function does not return a value. - It can also specify a pointer type that does not have a specific data type associated with it.
Derived Data Types
- Derived data types in C include arrays, structures, unions, and pointers.
- These types are built from primitive data types, allowing for more complex data handling.
Pointers in C
- Pointers store memory addresses of other variables, providing direct access to memory locations.
- They enable dynamic memory allocation and efficient data manipulation.
