In any programming language loops are used to execute a set of statements repeatedly until a particular condition is satisfied.           The loop directs a program to perform a set of operations again and again until a specified condition is true. Looping statement is used when we want to execute statements until a condition is true.C contains following type of looping statement:- * The for loop * The while loop * The do-while loop   * For loop:-            for loop is used to execute a set of statements for a given number of times , means if we want to execute statements till a certain number of time , for loop is used.   Syntax:                  for(start value; end value ; increment/decrement)                    {                           statement;                       } The for loop is commonly used when the number of iteration is known. So a for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a speci

    All c language must have a main() function. It's the core of every program. The main() function doesn't really have to do anything other than be present inside your 'C' source code.Eventually, it contains instructions that tell the computer to carry out whatever task your program is designed to do. abut it's not officially required to do anythings.                 The main() function uses its parentheses to contain any information typed after the program name at the command prompt. This is useful for more advanced programming.              Beginning programmers should keep in mind what those parentheses are there for , but you should first build up your understanding of c before you dive into that quagmire.           The braces are used for organization. They contains programming instructions that belong to the function. Those programming instructions are how the function carries out its task or does its thing.       Main function is very necessary fo

          The structured programming refers to the process in which we break the overall job down into separate pieces of modules.The modules are further can be broken into smaller sigments or pieces which are known as submodules . Modules must be chosen in such a way that we can specify how there is a contact between each pair of modules.  This specifies two things:- 1] What the module will do? 2] What assumptions is it making about the behaviour of the other modules? In particular, we must specify what inputs a particular module is to recieve from the various other modules and what outputs it is required to provide for them.   In other words, structured programming is a subset of procedural programming that enforces a logical structure on the program being written to make it more efficient and easier to understand and modify. Structured programming frequently employs a top-down design model,in which developers map out the overall program structure into separate subsection
