MCQs on Programming Concepts

Which of the following is the first step in program development?

• Coding

• Testing

• Problem definition

• Documentation

A program is best defined as:

• A collection of data

• A sequence of instructions to solve a problem

• A flowchart representation

• None of these

Which of the following is not a characteristic of a good program?

• Reliability

• Readability

• High complexity

• Efficiency

In program development, flowcharts are used for:

• Writing machine code

• Pictorial representation of logic

• Memory allocation

• None of these

An algorithm should always have:

• Infinite steps

• Well-defined inputs and outputs

• Only one step

• Ambiguous instructions

The stage where the program is tested with sample data is:

• Debugging

• Testing

• Compilation

• Documentation

Which programming methodology starts with breaking down the main problem into smaller sub-problems?

• Bottom-up approach

• Top-down approach

• Hybrid approach

• Iterative approach

In the bottom-up approach, development begins with:

• Writing main function first

• Developing small modules first

• Creating flowcharts

• Writing documentation

Pseudocode is:

• Executable program

• English-like representation of logic

• Flowchart symbol

• Machine code

The symbol used for decision-making in a flowchart is:

• Oval

• Rectangle

• Diamond

• Parallelogram
