6.02: Branching, Conditionals, and Iteration

Description
In general if statements are executing sequentially in the order which they appear, then there will be no problem. In practice , we have a number of situations where we may have to change the order of execution based on certain conditions or repeat a group of statements until certain specified conditions are met. Hence , each programming language must possesses such decision making capabilities by supporting some statements such as IF, Switch, Goto, Whie-Do,Do-While, for statement ..etc.
