User-defined functions Function Prototype Function call Function definition User-defined functions : These functions are defined by the user for there own prupose. These functions contains the following components :  (a) Function Prototype. (b) Function call (c) Function definition  (a) Function Prototype : The function prototype is used to specify the layout of the function. The function prototype specifies the following information :  (i) The function name  (ii) The number of arguments the function requires (iii) The type of  arguments  (iv) The returntype. The general form is , return type function name(argument list); Example 1 :  int sum(int ,int); It specifies that there will be a function with the name  sum( ) and this function will take two arguments and both are of type integers and the sum() will also return the integer type value. float average(f...

What is Functions Function is the block of code which is used to perform a particular operation. There are two type of the functions :  (i)  Pre-defined functions  (ii) User -defined functions . Monolithic Programming : In this case , we write the entire login in the single program/ The disadvantages of the monolithic programming are, (a) Difficult to understand. (b) Difficult to modify (c) Difficult of debug. [ Bug means computer program error and debugging is the process of locating and removing the computer    program error .]   Modular Programming : In the case of the modular programming , we divide the entire complex program into the simple sub-programs or modules.These modules are also known as functions. Advantages of the modular programming :  (a) Easy to understand  (b) Easy to debug (c) Easy to modify  (d) Resuability of code. (i) Pre-defined Funct...
