Day 14

 Hello my friends, today we complete the stages of learning how to write programming languages.

The fourth stage is:

Code debugging

Most programming languages today provide a debugging feature, which allows the programmer to run the program to check and search for errors, so that the execution of the code can be traced, each part (line, function, etc.) separately, the values of the defined variables, the sequence of function calls, and other valuable information.

Debugging the code is one of the most effective ways to find errors, and integrated development environments make the task much easier by providing smooth and intuitive graphical interfaces. This is a screenshot taken from the JetBrains website where they explain the debugging feature. Notice the ability to view the current variable values, the sequence of function calls, the line currently being executed, with a command window that you can use to execute any instruction interactively with the code, and much more.
