Advanced Calculator

This calculator program is designed to handle complex mathematical expressions with multiple levels of parentheses and different types of operators.

Features

• Validating the parentheses structures, unmatched or not even
• Formatting the trailing zeros after computation
• Supports addition, subtraction, multiplication, modulo, and division operations.
• Handles parentheses of different types: (), [], {}.
• Restructure the parentheses as there is no multiplication sign between two different scopes of parentheses
• Evaluates expressions based on the correct mathematical precedence rules:
  • Parentheses are evaluated first, starting from the innermost level.
  • Multiplication and division are evaluated next, from left to right.
  • Addition and subtraction are evaluated last, from left to right.
• Explaining the solutions step by step.
• Storing the problems along with answers to look up.

Usage

Enter your mathematical expression at the prompt. Use the following symbols for operations:

• Addition: +
• Subtraction: -
• Multiplication: *
• Division: /
• Modulo: %

You can also use parentheses to group operations. The calculator supports the following types of parentheses: (), [], {}.

Troubleshooting

-If you're having trouble with the calculator, ensure you're using the correct symbols for operations. The calculator uses the / symbol for division, not the ÷ symbol.

-Retyping the prompt will help somehow solve the "There is only one number" error. The mod symbol, "%," is one of the reasons if you copied from other sources.

Bugs

• The "%" sign is not read correctly
• ld: warning: ignoring duplicate libraries: '-lc++,' the Makefile problem.

Future Implementation

• input validation & error handling (words or numeric)
• exponents ( treat ^x as the operator and fix its precedence)
• roots
• trigonometry
• summation signs
• graphical interface
• learn more about header files, implementation of Guard Clause, and software developments

Compilation

https://www.onlinegdb.com/ The online compiler will make compiling the program much easier to check whether it is functioning well. If not,

• installing MinGW or Cygwin, which are software packages that provide a collection of GNU software, including the GCC compiler, for Windows.
• installing Xcode in Mac for g++ compiler
• After that, type 'make' to compile the program
