问我应该在if()中加入什么条件来计算数组中的所有正整数？

EN

require './input_functions.rb'

def main

arraya = Array.new (10)
num = 5

for x in 0..arraya.length-1
arraya[x] = num
num -=1
end

show(arraya)

puts "Enter a new integer:"
r = gets.chomp.to_i

p = read_integer_in_range("Select an index in the array to store a new integer ", 0, 9)
arraya [p] = r

show(arraya)

sum = 0
for x in 0..arraya.length-1
    if(x > -1)
        sum +=arraya [x]
    end


end

puts "The total of all the positive integers is " + sum.to_s
end

def show (arrayb)
for x in 0..arrayb.length-1
puts arrayb[x]
end
end
main

def read_integer_in_range(prompt, min, max)
value = read_integer(prompt)
while (value < min or value > max)
    puts "Please enter a value between " + min.to_s + " and " + max.to_s + ": "
    value = read_integer(prompt);
end
value
end
