Oct 12, 2021 · Following are some important points about functions in C. 1) Every C program has a function called main () that is called by operating system when a user runs the program. 2) Every function has a return type. If a function doesn’t return any value, then void is used as a return type.

A function definition in C programming consists of a function header and a function body. Here are all the parts of a function −. Return Type − A function may return a value. The return_type is the data type of the value the function returns. Some functions perform the desired operations without returning a value.

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“. I have written a separate guide for it. C Functions Terminologies that you ...

12.10.2021 · In C, we can do both declaration and definition at the same place, like done in the above example program. C also allows to declare and define functions separately, this is especially needed in the case of library functions. The library functions are declared in header files and defined in library files. Below is an example declaration.
