Write a program that reads a 6-digit number then adds up and displays th sum of its too middle digits. Example: x = 376954 Sum 6+9= 15 = Desired output format: (user input is underlined) Enter a 6-digit number: 376954 The sum of the two middle digits is: 15 Question #2: C++ Write a program that evaluates and prints the value of z for values of x and y entered by the user, where z = (x + y) 2 (x 2 + y 2). Desired output format: (user input is underlined) Enter the first number: 1 Enter the second number: 2 The expression value is: 45 Write a program that reads a 6-digit number then adds up and displays th sum of its too middle digits.
