Assignment #1 - Simple Calculator Write a CH program to create a simple calculator that can perform the basic four mathematical operation (add, subtract, multiply or divide). The program should perform the following procedure: 1. A welcome message should reflect at the beginning of the program. 2. After the welcome message another message should reflect so the user will input the first number (operand). 3. After you had input the first number, another message will indicate which mathematical operation the user would like to use (addition, subtraction, multiplication or division) 4. After you had selected the mathematical operation, another message should reflect so the user will input the second number (operand). 5. Finally, a message will indicate the total. The C++ program should have the following: Variables, Data types, Literals Constants and Operators if, else if and else Statement (do not use Switch Statement) Note: Be creative and proactive when you are writing the program
