How do you write an algorithm to find whether a given number is odd or even?

1 Answer

1. Step 1: Start.
2. Step 2: Read a number to N.
3. Step 3: Divide the number by 2 and store the remainder in R.
4. Step 4: If R = O Then go to Step 6.
5. Step 5: Print “N is odd” go to step 7.
6. Step 6: Print “N is even”
7. Step 7: Stop.

How are algorithm and flowchart related to one another?

Algorithms and flowcharts are two different tools that are helpful for creating new programs, especially in computer programming. An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way.

What is the sum of any 2 even numbers?

Since the sum of two integers is just another integer then we can let an integer n be equal to (x+y) . Substituting (x+y) by n in 2(x+y), we obtain 2n which is clearly an even number. Thus, the sum of two even numbers is even. For example, 2+2=4, 2(3)+2(5)=16, etc.

What is the sum of any two add number?

even number
The sum of any two odd numbers is always an even number.

How to find whether a number is even or odd?

FlowChart and Algorithm to find Whether a Number is Even or Odd. Even Number: An even number is an integer which is exactly divisible by 2. Example: 0, 6, -26. Odd Number: An odd number is an integer which is not exactly divisible by 2. Example: 1, 9, -13, 19.

How to create an algorithm flowchart?

Follow the steps below: 1 Select an appropriate template. 2 Customize the template according to your needs. 3 Add content to the template. 4 Export your algorithm flowchart to the file format that you want.

How do you find the sum of even integers between 2-18?

If the value of count started at 2 and ended at 18, with count incremented by 2 instead of 1, checking for evenness could be avoided. sum of 2*n from n = 1 to m/2 = (1/4)*m* (m+2). Set m = 18 and evaluate the expression. Note: this is summing even integers starting at 2 and ending at 18 (even integers between 1 and 20, not including 20).

What is the first even number between 1 and 20?

We initialize NUMBER = 2 which is the first even number between 1 and 20. Then we ask if NUMBER > 20 which it won’t be the first time.
