Create a list with at least five (5) strings to be used as usernames. Create a corresponding list of five (5) strings to be used as passwords (one for each username). Invite the user to enter a username. If it is in the list, invite them to enter a password. If the password matches, print a welcome message using their username. If the user enters a username that is not on the list or enters a password that does not match, print an appropriate message to inform them. For example if the usernames were matwood, wshakes, sking, rmunch, jrowlin and passwords were handmaids, hamlet, It, BeQuiet, Potter then entering sking followed by It would give a welcome message whereas entering sking followed by Hamlet would not.
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
