The succ 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.succ
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
# Ruby program for succ function # Initializing the numbers num1 = 100
num2 = 17
num3 = - 90
num4 = - 29
# Printing the next value puts num1.succ puts num2.succ puts num3.succ puts num4.succ |
Output:
101 18 -89 -28
Example 2:
Ruby
# Ruby program for succ function # Initializing the numbers num1 = 19
num2 = - 17
num3 = - 18
num4 = 16
# Printing the succ value puts num1.succ puts num2.succ puts num3.succ puts num4.succ |
Output:
20 -16 -17 17
