It is convenient to keep the logic of the loop and the inner logic of the root finder separate. In a larger program, the root finder might be made a separate function.

Each part of the program can be worked on separately. In a big project, each might be assigned to a different programmer or programming team.

For now, let us work on the user control of the loop and deal with the root finder later. User interaction can be tricky, especially in C. It is often smart to get it working before moving on to other parts of a program.
