Functions In C Programming Language Hubpages A function in c language is a block of code that performs a specific task. it has a name and it is reusable i.e. it can be executed from as many different parts in a c program as required. it also optionally returns a value to the calling program. so function in a c program has some properties discussed below. every function has a unique name. Functions with no arguments and return values. 1. functions with no arguments and no return value. a c function without any arguments means you cannot pass data (values like int, char etc) to the called function. similarly, function with no return type does not pass back data to the calling function. it is one of the simplest types of function.
Types Of Function In C Programming Language Hubpages C is the most popular programming language developed by dennis ritchie at the bell laboratories in 1972 to develop the unix operating systems. it is a general purpose and procedural programming language. it is faster than the languages like java and python. c is very versatile it can be used in both applications and technologies. c is the most used. For example, we can use the following code to call the sum function that we defined earlier: int a = 5; int b = 10; int c = sum(a, b); in this code, we are calling the sum function with a and b as its parameters. the function returns the sum of a and b, which is then stored in the variable c. C functions. a function is a block of code that performs a specific task. suppose, you need to create a program to create a circle and color it. you can create two functions to solve this problem: create a circle function. create a color function. dividing a complex problem into smaller chunks makes our program easy to understand and reuse. C functions. c. functions. a function is a block of code which only runs when it is called. you can pass data, known as parameters, into a function. functions are used to perform certain actions, and they are important for reusing code: define the code once, and use it many times.

Few points to note regarding functions in c: 1) main() in c program is also a function. 2) each c program must have at least one function, which is main (). 3) there is no limit on number of functions; a c program can have any number of functions. 4) a function can call itself and it is known as “ recursion “. Every ‘c’ program has at least one function which is the main function, but a program can have any number of functions. the main function in c is a starting point of a program. in ‘c’ programming, functions are divided into two types: library functions; user defined functions; the difference between the library and user defined.
