Question

Create an algorithm and a flowchart that

will compute the sum of two numbers. If

the sum is below or equal to twenty, two

numbers will be entered again. If the sum

is above 20, it will display the sum.​

Answer 1

Answer:

Step 1: Start

Step 2: Declare variables num1, num2 and sum.

Step 3: Read values for num1, num2.

Step 4: Add num1 and num2 and assign the result to a variable sum.

Step 5: Display sum

Step 6: Stop

Flowchart:-

Answer 2

Answer:

written below-

Explanation:

An algorithm is a set of well-defined instructions in sequence to solve a problem.

Some good qualities of an algorithm are:

Input and output should be defined precisely.

Each step in the algorithm should be clear and unambiguous.

An algorithm shouldn't include computer code. Instead, the algorithm should be written in such a way that it can be used in different programming languages.

Produces desired output.

General flow of an algorithm is Start → Declare variables → Initialise variables → Perform operation → Display output → Stop.
