IMPORTANT QUESTIONS AND ANSWERS

ALGORITHM & FLOWCHART

Q1. Describe the following steps of problem-solving process.

1. Define the problem
2. Analyze the problem
3. Planning the solution of the problem
4. Find candid solutions of the problem
5. Select the best solution

Q2. Define an algorithm.

Q3. Define a program flowchart

Ans. Flowchart is combination of two words flow and chart. A chart consists of different symbols to display information about any program. Flow indicates the direction of processing that takes place in the program.

Q4. Describe the importance of program flowchart for solving a problem.

Ans. Flowchart is a graphical representation of an algorithm. It is a way of visually presenting the flow of data the operations performed on data and the sequence of these operations. Flowchart is similar to the layout plan of a building. A designer draws the layout plan of the building before constructing it. Similarly, a programmer prefers to design the flowchart before writing the computer program.
