A function consist of two parts: Declaration: the function's name, return type, and parameters (if any) Definition: the body of the function (code to be executed)
- Advantages of C Functions: Here are some main advantages of Functions in C: Code Re-usability: We can call the C Functions many times. So there will be no need to write the same code again and again.
- Function Declaration/Function Prototype. Declaration of C Function, tells the compiler about a function’s name, it’s the return type and the parameters.
- Syntax of Declaration of Function. return_type function_name(data_type parameter, data_type parameter) { // code to be executed } Example of Function Declaration/Prototype.
- Definition of C Functions: When we define a function, we provide the actual body of the function. A function definition provides the following parts of the function.
C allows you to define functions according to your need. These functions are known as user-defined functions. For example: Suppose, you need to create a circle and color it depending upon the radius and color. You can create two functions to solve this problem: createCircle() function. color() function. Example: User-defined function.
