The concept of defining user-defined functions and then calling them from inside the program itself is almost a requisite feature of C. This chapter instructs the reader in how to define and integrate such user-defined functions in the code. An important aspect of this is ensuring that the ...
Functions reduces the repetition of code within a program— Function allows you to extract commonly used block of code into a single component. Now you can perform the same task by calling this function wherever you want within your script without having to copy and paste the same block of ...
