Concept:Program development always begins with a clear understanding of what needs to be solved.
Explanation:The first step in creating any program is to define the exact problem.
This means stating the issue clearly in the user's terms before writing code.
Problem definition involves determining the goal, required inputs, expected outputs, and constraints.
For example, if a school wants a grading system, the problem is first stated as "calculate and display each student's grade based on marks."
Only after this clear definition can analysis, design, coding, testing, and implementation proceed effectively.
Problem analysis comes later and focuses on how to solve the defined problem.
Therefore, the very first stage in program development is problem definition, not problem analysis, solving, or testing.
Answer:B. definition.
