C. Fill in the blanks.
1. The errors in a program are known as ____________.
2. A _______________ is a diagrammatic representation of an algorithm.
3. A program written in a high-level language is known as _____________.
4. A compiler converts a source code into _____________.
5. ______________ is a way to find and fix bugs in software or applications.
D. Answer the following questions:
1. List the steps involved in the Problem-Solving Cycle.
Ans. • Problem Analysis
• Program Design
• Coding
• Testing and Debugging
2. How is an algorithm different from a flowchart?
Ans. An algorithm is a step by step description of solution to a problem in simple language. A flowchart is a diagrammatic
representation of an algorithm.
3. Write an algorithm to accept two numbers and display their sum and product. Also draw a flowchart.
Ans. Input: two numbers num1, num2
Process: Compute sum and product of num1 and num2
Output: sum and product of num1 and num2
input num1 and num2
compute sum = num1 + num2, product = num1 * num2
print sum, product
Flowchart:

Start

input num1, num2

sum = num1 + num2
product = num1 * num2

print Sum, Product

Stop

4. Write an algorithm and draw a flowchart to accept three numbers and display the largest number.
Ans. Input: Three numbers num1, num2, num3
Process: The number which is larger than each of the other two is the largest of the three numbers
Output: Largest of three numbers num1, num2, and num3
