Equation solver

Equation solver developed using Test Driven Development. The solver supports the following operations:

• Addition
• Subtraction
• Multiplication
• Division
• Exponentiation

Usage

Compile using cmake:

cd equation-solver
mkdir build
cd build
cmake ..
cmake --build . --target equation_solver

Execute passing the equation to solve as argument:

./equation_solver "x = 10"

Examples

Some examples of equations accepted by the solver:

• Basic example: "x = 10"
• Plus and minus: "12x + 45 = 90 - 18"
• Times: "4x * 2 - 12 = 8 * 7x + 54 * 2"
• Divide: "16 / 4 + 42x / 2 = 82 / 41"
• Floating point numbers: "45.2 * 3x = 0.8 + 56.32 - 3.4x"
• Power: "4.5x^4 + 8^2^2 = 3.3x^2^2 - 2^0"

Order of operations

The operations are solved following this order:

1. Exponentiation
2. Divisions (transformed into multiplications)
3. Multiplications
4. Additions and subtractions

Future developments

• Parentheses
