Write a do while loop in C++ that validates an input classCode. The valid inputs are ‘F’, ’S’, ’J’, or ’R’. Use a boolean variable invalid to assign the invalid expression.  Have it output the input and either “ is an INVALID INPUT – Please try again!”  or  “ is valid – thank you!”.   For Example:  G is an INVALID INPUT – Please try again!   OR  F is valid – thank you!     Use the following declarations

In java, create a program that will use a do while loop with a "yes/no" prompt. The program should include user input and output with getters and setters. Once the end of the loop is reached, ask the user if they'd like to do the program again. Answering "Yes" will start the program over again. Answering "No" will end the program. Answering with anything else will be an invalid input. Once the loop begins again, the program should also discard all previous inputs so that there won't be any overlapping. Use Scanner.nextLine();, it will help.

Write a program in C++ which adds, subtracts, multiplies, divides and performs exponentiation on two specific numbers. The two numbers should be entered by the user. Each output should include a string describing what the numerical output is being displayed. Use the if-else-if ladder so that the user is able to select which mathematical function to perform. Make sure the program has a neat menu for the user to use to select their choice. Also, avoid having the computer perform a division by zero if the user attempts it by outputting a warning message in its place (use an if-else statement). Include your C++ source code as well as the output of your program in your submission

*Modify the program so that the user will error trap for only 1 and 0 as an input.   *If the user enters an input other than 1 or 0 display an error message and request the user enter that input again.  *Do this for all inputs in the code.     # User defined function for logic OR# The function takes two parameters and returns a single intdef OR(a: int, b: int)->int:# If a is equal to 1 return 1if a == 1 :return 1# If b is equal to 1 return 1elif b == 1 :return 1# If a and b is equal to 0 return 0else :return 0 # User defined function for logic NOR# The function takes two parameters and returns a single intdef NOR(a: int, b: int)->int:# If a is equal to 0 and b is also equal to 0 return 1if a == 0 and b == 0 :return 1# If a is equal to 0 and b is equal to 1 return 0elif a == 0 and b == 1 :return 0# If a is equal to 1 and b is also equal to 0 return 0elif a == 1 and b == 0 :return 0# If a is equal to 1 and b is also equal to 1 return 0elif a == 1 and b == 1 :return 0 # User defined…
