PROGRAMMING LANGUAGE: C++ ALSO PASTE SCREENSHOTS OF OUTPUTS Write a program that takes +,-,*, and / operators and performs the required operation. the program will continue to execute until ESC key is pressed. Also, the usage of post-test loop and switch statement is mandatory.

*Using C# in Microsoft Visual Studio* create an application that lets the user enter a nonnegative integer and then uses a loop to calculate the factorial of that number. Display the factorial in a label or a message box. If the input is nonnumeric your program SHOULD NOT CRASH but display a message ""non numeric input". If the input is negative display the message ""negative numbers are invalid.

c++ problem

Cases in a switch statement are evaluated sequentially (called "fall through") unless they are terminated with break statements.

True or False: C++ uses negative values to represent "False" and positive values to represent "True". It is possible that the body of a while loop may not execute at all.

In C programming: A while loop will always be executed at least once, even if expression is initially zero. True False The while and for loops are known as the "test-at-the-top" loops. * True False

in C#

The Step Out function executes one source line of a program. If the line is a function call it executes the function and returns control to the main window to the caller to the assignee to the debugger

Drawa structured flowchart , C++, write pseudocode that describes the process of guessing a number between 1 and 100. After each guess, the player is told that the guess is too high or too low. The process continues until the player guesses the correct number. Pick a number and have a fellow student try to guess it following your instructions.

A first block statement is invalid beyond a specified time.
