The third project involves modifying the attached interpreter so that it interprets programs for the complete language. You may convert all values to double values, although you can maintain their individual types if you wish.

For example, for the following function header of a program in the file text.txt: function main a: integer, b: integer returns integer; One would execute the program as follows: $ ./compile < test.txt 2 4 In this case, the parameter a would be initialized to 2 and the parameter b to 4. An example of a program execution is shown below:
