In this article **Algorithm example** we give the different examples of algorithm such as **Prime number algorithm**, Area of circle algorithm, Factorial algorithm etc.

**Algorithm Example:**

**Q1. Write an algorithm to display addition of two numbers.**

Step 1: Start

Step 2: Declare variables num1, num2 and sum.

Step 3: Read values num1 and num2.

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

Step 5: Display sum * *

Step 6: Stop

**Algorithm Example:**

**Algorithm 1: Find the area of rectangle**

Step 1: Start

Step 2: Declare variables l, b and area.

Step 3: Read values l and b.

Step 4: Product l and b and assign the result to area.

area<- l * b

Step 5: Display area.

Step 6: Stop.

**Algorithm 2: Find the area of circle**

Step 1: Start

Step 2: Declare variables r and area.

Step 3: Read value r.

Step 4: Calculate r into r into 3.142 and assign the result to area.

area<- r * r * 3.142

Step 5: Display area.

Step 6: Stop.

**Algorithm 3: Find the Volume of Cube**

Step 1: Start

Step 2: Declare variables s and volume.

Step 3: Read value s.

Step 4: Calculate s into s into s and assign the result to volume.

volume<- s * s * s

Step 5: Display volume.

Step 6: Stop.

**Algorithm 4**: **Write an algorithm to swap two numbers using the third variable**

Step 1: Start

Step 2: Declare variables a, b and t.

Step 3: Read value a and b.

Step 4: Display values a and b (Before Swap)

Step 5: t = a

Step 6: a = b

Step 7: b = t

Step 8: Display values a and b (After Swap)

Step 9: Stop.

**Algorithm 5**:

**Calculate simple interest. **

Step 1: Start

Step 2: Declare variables p, r, y and SI.

Step 3: Read value p, r and y.

Step 4: Calculate p into r into y divided by 100 and assign the result into SI

Step 5: Display SI

Step 6: Stop.

**Algorithm 6: Find the largest number among two numbers**

Step 1: Start

Step 2: Declare variables a and b.

Step 3: Read values a and b.

Step 4: If a > b

Display a is the largest number and goto step 5.

Else If b > a Display b is the largest number.

Else Display both are equal numbers.

Step 5: Stop

**Algorithm 7: Find the largest number among three numbers**

Step 1: Start

Step 2: Declare variables a, b and c.

Step 3: Read values a, b and c.

Step 4: If a > b , If a > c

Display a is the largest number.

Else If b > c Display b is the largest number.

Else Display c is the greatest number.

Step 5: Stop

**Algorithm 8: What is the algorithm for even or odd number?**

Step 1: Start

Step 2: Declare variables a.

Step 3: Read values a.

Step 4: If a % 2 = 0 then

Display a is the even number.

Else Display a is the odd number.

Step 5: Stop

**Algorithm 9: **

**To display factorial of given number**

Step 1: Start

Step 2: Declare variables a and fact.

Step 3: Initialize value fact=1

Step 4: If a greater than 0 then a=4 , 3 , 2 , 1 , 0

assign fact= fact into a fact=4 , 12 , 24 , 24

Step 5: assign a= a-1 and goto step 4 a= 3 , 2 , 1 , 0

Step 6: display value of fact

Step 7: Stop
