The next function in Ruby returns the immediate successor of the number, i.e., it returns number + 1. If a float value is used, it throws an error message.
Syntax: number.next
Parameter: The function takes the integer whose next is to be returned.
Return Value: The function returns the immediate successor of the number, i.e., it returns number + 1
Example #1:
# Ruby program of next function # Initializing the numbers num1 = 100
num2 = 17
num3 = -90
num4 = -29
# Printing the modulo value puts num1.next
puts num2.next
puts num3.next puts num4.next |
Output:
101 18 -89 -28
Example #2:
# Ruby program of next function # Initializing the numbers num1 = 19
num2 = -17
num3 = -18
num4 = 16
# Printing the modulo value puts num1.next
puts num2.next
puts num3.next puts num4.next |
Output:
20 -16 -17 17
