simple-interpreter

Interpreter for a made-up programming language.

Note: This project was for coding practice, it likely does not contain any groundbreaking new features!

Input format

The file input.txt should contain each instruction on a new line

Our simple programming language allows:

• variables which are a single letter e.g. A
• whole numbers e.g. -5, 0, 20
• assignment (=) e.g. A = 5, B = A
• addition of 2 elements e.g. B = A + 1, C = A + B
• returning a value e.g. A, B, 20

Example operation

Input

For an example of how the input should be formatted, see input.txt.

The initial contents of the input file are:

A = 2
B = 8 + 7
C = A + B
D = C + A
D

Output

Interpreter output:
19

How to run

• Download the repository
• Compile the .java file and then run it
• Check the console for the expected output above
• Try changing the input.txt file and running again
