Quiz on Flowchart

What is the purpose of a flowchart in programming?

• To debug errors in the code

• To represent the step-by-step solution of a problem graphically

• To write the actual code in a programming language

• To execute the program and produce the output

Which symbol is used in a flowchart to indicate the start and stop of a program?

• Diamond shape

• Rectangle with curved ends

• Parallelogram

• Circle

What is the purpose of pseudo code in programming?

• To describe the steps of a program solution informally

• To write code using strict programming language syntax

• To execute the program directly on the computer

• To design user interfaces for software applications

Which symbol is used in a flowchart to represent a decision or condition in the program?

• Rectangle with curved ends

• Circle

• Diamond shape

• Parallelogram

What is the main advantage of verifying an algorithm using a dry run or trace tables?

• To ensure the logic of the program is correct before writing actual code

• To optimize the program for faster execution

• To test the program on different operating systems

• To create a graphical user interface for the program

What is the purpose of using a connector in a flowchart?

• To write comments or annotations

• To connect flowcharts on different pages

• To input data

• To find the factorial of a number

What does the factorial of a number represent?

• The division of all numbers till that number

• The multiplication of all numbers till that number

• The sum of all numbers till that number

• The average of all numbers till that number

In the algorithm for finding the factorial of a number, what is the first step after starting the program?

• Print the value of the factorial

• Multiply all numbers from 1 to n

• Input the number whose factorial is to be found

• Assign values to variables

What is the purpose of the 'while' loop in the pseudo code for finding the factorial of a number?

• To input the number

• To check if the number is odd or even

• To print the value of the factorial

• To repeat steps until a condition is met

Why is it important to verify the logic using flowcharts, algorithms, or pseudo code before coding?

• To confirm the logic is correct

• To make the code more complex

• To ensure the code runs faster

• To save time
