In Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In this lab, you will add some more functionality to the program. Use loops to keep running the program until the user chooses the exit condition (9). When dividing, use a loop to validate user input, making sure the denominator (second number) is not zero. If the user enters a 0 for the second number, display an error message and keep prompting until a non-zero number is entered. 1) Add two numbers2) Subtract two numbers3) Multiply two numbers4) Divide two numbers 9) Exit program The program should: contain header comments as shown in class display a hello message before presenting the menu display the menu prompt user for selection echo the selection back to the user if the selection was invalid, display error message to user and then loop back to menu if the selection was valid, prompt the user for two numbers if the operation is division, and the second number is zero, display error message to user and then loop (with new prompt) until non-zero number is entered for any other scenario, perform the operation and display the results use loop to present menu again and ask for another selection continue looping until user selects exit condition display a goodbye message before exiting the program HINT: The loop should continue until some condition is false. What is that condition? When should it be set false? Consider using a flag variable for the loop... Make it as simple as you can please. :D Language is C++
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.
In Lab 2, you created a menu for a simple calculator
1) Add two numbers2) Subtract two numbers3) Multiply two numbers4) Divide two numbers
9) Exit program
The program should:
- contain header comments as shown in class
- display a hello message before presenting the menu
- display the menu
- prompt user for selection
- echo the selection back to the user
- if the selection was invalid, display error message to user and then loop back to menu
- if the selection was valid, prompt the user for two numbers
- if the operation is division, and the second number is zero, display error message to user and then loop (with new prompt) until non-zero number is entered
- for any other scenario, perform the operation and display the results
- use loop to present menu again and ask for another selection
- continue looping until user selects exit condition
- display a goodbye message before exiting the program
HINT: The loop should continue until some condition is false. What is that condition? When should it be set false? Consider using a flag variable for the loop...
