For this assignment, you are required to develop a non-scientific calculator using C. Your

calculator should only solve summation, subtraction, division, product, square root and square

expressions. Utilizing the math.h header for your program, your calculator should start by

prompting the user to enter a two-or-more-operand mathematical equation just like how you

would using a non-scientific calculator. Your program should then display the correct

answer and the user will have the choice to either continue using the calculator with the

current answer to perform further calculations or end the program. Your program should also

have a help function to display all the functions of the calculator. A sample output of the

program when the user enters “help” is shown below:

Your calculator must have the following additional functionalities and features:

1. Your calculator should display values accurate up to 6 decimal places.

2. For square and square root operations, you may define any symbol to represent the

operations, but the user should be aware of the symbols you used.

3. Have a memory function to store the current answer and can be used later for further

calculations and reference.

4. Have a refresh function to erase the stored memory and return the calculator to its initial

‘start-up’ mode.

Below are some examples of the program output:
