Monty 0.98 is a scripting language that is first compiled into Monty byte codes (Just like Python). It relies on a unique stack, with specific instructions to manipulate it. The project is an interpreter for Monty ByteCodes files.
Ensure that you have gcc installed and build the program with bash ./build.bash. This would generate an executable called monty. Run the program with ./monty file.

| add | Adds the top two elements of the stack |
| nop | Does nothing |
| sub | Subtracts the top element of the stack from the second top element of the stack |
| div | Divides the second top element of the stack by the top element of the stack |
| mul | Multiplies the second top element of the stack with the top element of the stack |
| mod | Computes the rest of the division of the second top element of the stack by the top element of the stack |
| pchar | Prints the char at the top of the stack, followed by a new line |
| pstr | Prints the string starting at the top of the stack, followed by a new line |
| rotl | Rotates the stack to the top |
