Answer:

Hand tracing.

Explanation:

Similar to regular debugging which is mainly used for finding errors, hand tracing or simply tracing, is the process of stepping through each statement while tracking and recording the value of specific variables at each step. Tracing is a debugging process which allows programmers to get required information about how a program executes or how it works.

To perform hand-tracing, the programmer might add tracing messages at logical points of the code. Like comments, tracing messages can enhance readability and understandability of the code or program.

<em>PS: Tracing can even be done without a computer. </em>
