Need Of Functions In Programming | C Programming

A function is a self-contained block of program statements that performs a specific task. Imagine a program wherein a set of operations has to be repeated often, though not continuously, n times or so. If they had to be repeated continuously, loops could be used. Instead of inserting the program statements for these operations at so many places, write a separate program segment and compile it separately as many times as it is needed, keep ‘calling’ the segment to get the result. The separate program segment is called a function and the program that calls it is called the ‘main program’. C went one step further; it divided the entire concept of programming to a combination of functions. C has no procedures, only functions. scanf(), printf(), main(), etc. that have been used in programs so far, are all functions. C provides a lot of library functions; in addition, programmers can write their own functions and use them. The special function called main() is where program execution begins. When a function is called upon, with or without handing over of some input data, it returns information to the main program or calling function from where it was called.
