end

when i execute this code there are error why ??

Answer 1

that way ??:
age = gets.chomp()
if (age. to_i > 18) then
print "you are major "
end

is it correct??

Answer 2

it don't work
look at
age = gets.chomp()
if (age. to_i > 18) then
print "you are major "
end
they say no output

Answer 3

age is being treated as a string
To use it as an integer you have to:
1. Remove newline character
For this use gets.chomp() instead of gets()
2. Convert to integer
Do age.to_i to use as integer

Answer 4

Should be.
Just as a remark you don't need the 'then'
