 # R Program to check odd and even number

## How to check the given number is a odd or even

Here we are explaining how to write an R program to take number from the user and check it is an odd or even. we can use the `readline()` function to take input from the user (terminal). Here the prompt argument can choose to display an appropriate message for the user.

## How odd or even number check is implemented in R Program

We are using `readline()` function for taking the user's input. Given below are the steps which are used in the R program to read value for odd or even check. In this R program, we accept the user's values into num by providing an appropriate message to the user using '`prompt`'. Check the given number is even if division by 2 otherwise it is an odd number.

## ALGORITHM

STEP 1: prompting appropriate messages to the user

STEP 2: take user input using `readline()` into variables num

STEP 3: check if num is exactly divisible by 2 gives a remainder of 0

STEP 4:if remainder is non zero print number is an odd number

STEP 5:if remainder is zero print number is a even number

## R Source Code

```                                          ```num = as.integer(readline(prompt="Enter a number: "))
if((num %% 2) == 0) {
print(paste(num,"is Even number"))
} else {
print(paste(num,"is Odd number"))
}```
```

## OUTPUT

```Enter a number: 60
 "60 is Even number"

Enter a number: 15
 "15 is Odd number"```
