This forum is here to answer questions about code. It is not here for people to debug your code for you. You need to do that so this would be a great time for you to learn how the debugger works because that is the best tool for this job.

Your scanf statement is wrong. Array names are already pointers so do not need the addressof (&) operator:

C++

// wrong
while (scanf("%s %s", &op, &buf) == 2)
// should be just:
while (scanf("%s %s", op, buf) == 2)

You also need to flush the input for the next scanf, as there will still be a newline character to be read.
