This File is all about a important topic 'Functions' which is a subtopic from C Programming. This concept is the base for a user to use that programming language. Why we need functions in C? a) To improve the readability of code. b) Improves the reusability of the code, same function can be used in any program rather than writing the same code from scratch. c) Debugging of the code would be easier if you use functions, as errors are easy to be traced.Everything related to functions are discussed in this ppt which will be very easy to understand the concept.This knowledge is written by experts.The first reason is reusability. Once a function is defined, it can be used over and over and over again. You can invoke the same function many times in your program, which saves you work. Imagine what programming would be like if you had to teach the computer about sines every time you needed to find the sine of an angle! You'd never get your program finished! Another aspect of reusability is that a single function can be used in several different (and separate) programs. When you need to write a new program, you can go back to your old programs, find the functions you need, and reuse those functions in your new program. You can also reuse functions that somebody else has written for you, such as the sine and cosine functions.This ppt helps you to understand the concept.
