Sure! Here’s a simple pseudocode to check if a number is even or odd:
```
BEGIN
FUNCTION IsEvenOrOdd(number)
IF number MOD 2 = 0 THEN
PRINT "The number is even."
ELSE
PRINT "The number is odd."
ENDIF
END FUNCTION
// Main program
DECLARE number AS INTEGER
PRINT "Enter a number: "
INPUT number
CALL IsEvenOrOdd(number)
END
```
### Explanation:
1. The function `IsEvenOrOdd` takes an integer input called `number`.
2. It checks if `number` modulo 2 equals 0. If true, the number is even; otherwise, it is odd.
3. The main program declares a variable to hold the number, prompts the user for input, and then calls the function to determine if the number is even or odd.
```
BEGIN
FUNCTION IsEvenOrOdd(number)
IF number MOD 2 = 0 THEN
PRINT "The number is even."
ELSE
PRINT "The number is odd."
ENDIF
END FUNCTION
// Main program
DECLARE number AS INTEGER
PRINT "Enter a number: "
INPUT number
CALL IsEvenOrOdd(number)
END
```
