Debuggers

Are tools used by programmers to identify and fix errors or bugs in their code.

Error Messages

Notifications or alerts that appear when there is an issue or mistake in a program. They provide information about the error and help programmers identify and fix the problem.

Hand Tracing

The process of manually following through lines of code step by step, keeping track of variable values at each point. It helps understand how code executes and aids in identifying errors or unexpected behavior.

Logic Errors

Are mistakes in a program's code that cause it to produce incorrect or unexpected results. These errors occur when there is a flaw in the logic or reasoning of the program, leading to incorrect output.

Print Statements

Are lines of code used by programmers to display output messages or variable values during program execution.

Test Cases

Specific inputs, conditions, and expected outputs used to verify the correctness and functionality of a program. They help identify errors or bugs in the code.

Testing

Refers to the process of evaluating a program or system to ensure that it functions correctly, meets its requirements, and produces expected results.

Visualizations

Refer to the use of graphical representations, such as charts or diagrams, to help understand and analyze data or processes.
