Who is responsible for designing the structure of a computer program?

A programmer is responsible for designing the structure of a computer program and converting a solution into executable code. Before writing the program, the programmer plans the program's logic, organizes its modules, selects suitable algorithms, and determines how different parts of the program will work together. Therefore, Option C (Programmer) is the correct answer.

After understanding the project requirements, the programmer creates the program structure using flowcharts, algorithms, or pseudocode. Once the design is complete, the programmer writes the source code in a programming language such as C, C++, Java, Python, or JavaScript. The programmer also tests, debugs, and maintains the program to ensure it functions correctly and efficiently.

Key Point:

• Programmer: Designs the program structure and writes the source code.


• System Analyst: Analyzes requirements and prepares system specifications.


• End User: Uses the completed software to perform tasks.

Exam Tip:

                  Remember the sequence: System Analyst → Programmer → End User. The system analyst defines the requirements, the programmer designs and develops the program, and the end user operates the finished software.
