Hello everybody, i am having a problem that i am not sure how to solve it, i am reading a text input from a file to the buffer and i wanna do some calculations on it , the file consists of arithmetic operations like add 10 and 20, how do i do that and at the same time keep in mind the space difference between the operands as in: add 10 20 and add 10 30 and so forth,
any guidance will be greatly appreciated
