The programmer usually enters source code into a computer using:
A. Pseudocode
B. A text editor
C. A hierarchy chart
D. A compiler
E. None of the above
The Correct Answer and Explanation is:
Correct Answer: B. A text editor
Explanation
When a programmer writes source code, they typically use a text editor. A text editor is a type of software application specifically designed for creating and editing plain text files. These editors are crucial tools for programmers because they allow the entry, modification, and saving of source code written in programming languages like Python, Java, C++, and others.
Text editors come in various forms, ranging from simple editors like Notepad (on Windows) to more sophisticated ones like Visual Studio Code, Sublime Text, Atom, and Vim. These advanced editors often include features such as syntax highlighting, auto-completion, debugging tools, and integration with version control systems like Git. These features improve the programmer’s productivity and reduce the likelihood of syntax and logical errors.
Let’s examine why the other options are incorrect:
- A. Pseudocode: This is a way to plan and visualize algorithms in a human-readable format before writing actual code. It is not used to enter executable source code into a computer.
- C. A hierarchy chart: This is a diagram that shows the structure of a program, such as the relationships between modules. It is useful for design purposes but not for writing or entering code.
- D. A compiler: A compiler is a tool that translates source code into machine code or intermediate code so that a computer can execute it. However, it does not provide a means to enter the source code; it only processes it after it has been written.
- E. None of the above: This is incorrect because one of the options—specifically, the text editor—is indeed the correct answer.
In conclusion, a text editor is the standard tool used by programmers to enter source code into a computer, making option B the correct choice.
