  1. Lab # 4

  2. Exercise 1 Convert each of the following formulas to a C++ expression:3x 3x + y x+y3x + y 7 z + 2 3*x 3*x + y (x+y)/7 (3*x + y)/(z+2)

  3. Exercise 2 What is the output of the following program lines, when embedded in a correct program that declares all variables to be of type char?a = 'b';b = 'c';c = a;cout << a << b << c << 'c'; bcbc

  4. Exercise 3 What is the output of the following program lines, when embedded in a correct program that declares all variables to be of type int? number = (1/3) * 3;cout << "(1/3) * 3 is equal to “ << number; (1/3)*3 is equal to 0

  5. Exercise 4 Write and run a program that simulates a simple calculator. It reads two integers and performs the simple calculator operations +,-,*, and / on them. The output should appear as follows:
