This is a simple console calculator which can calculate multiple expressions at once.
This project does not use any library related to data structures and algorithms. All data structures and algorithms are implemented from scratch.
This project can be built using CMake and the CMakeLists.txt file. Otherwise, any IDE would be sufficient.
Note: This project was built with the C++14 flag. Enable this flag to avoid compiling errors.
The program supports two different modes: input directly in the console, or input with a text file. Both relative or absolute path can be used for the file mode.
Each line must have the following syntax:
<variable> = <expression>
Supported operators:
+,-,*,/,^div,mod(integers only)- functions:
sin,cos,tan,cot,exp
pi constant is also supported.
Example:
- Input file:
a = 2 + 3 + (3)
b = a + 4
c = 3 * b - 3^2
d = c mod 4
e = 10 - 3 * 4
f = 100 - (2 + 3 * 4)
g = (1 + (10 * (3 - 2)))
h = sin(0.5)
i = exp(exp(0.5))
k = pi
x = 2
y = 3
z = x^2 + y^3
- Output:
