This lecture discusses the different types of functions in C programming, including void functions with arguments, formal parameters and actual arguments, and the reusability of functions. It also covers modular programming and the advantages of using function subprograms.

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.

C Functions Three major differences between C and Java functions Functions are stand-alone entities, not part of objects they can be defined in a file with other functions, or separately and then loaded as desired Function prototypes must appear in any file where functions are to be used
