每当我尝试运行程序时,会弹出一个错误,说"条件中的字符串文字(第10行)".我究竟做错了什么？
puts "Welcome to the best calculator there is. Would you like to (a) calculate the area of a geometric shape or (b) calculate the equation of a parabola? Please enter an 'a' or a 'b' to get started."
response = gets.chomp
if response == "a" or "A"
puts "ok."
elsif response == "b" or "B"
puts "awesome."
else
puts "I'm sorry. I did not get that. Please try again."
end
puts "Let's get started calculating your parabola. What is your A value?"
a = gets.chomp
puts "What is your B value?"
b = gets.chomp
puts "What is your C value?"
c = gets.chomp
x = x
2x = (x.to_i**2)
puts "Your parabola equation is 'y = " + a.to_s + 2x.to_s + " + " + b.to_s + x + " + " + c.to_s + "'. Would you like to go back to the beginning?"
我是一个初级程序员。我想调整我的按钮的大小，它被定义为“但是”，它是在 Square 类中定义的。我将使用什么选项来调整此按钮的大小以调整高度和宽度？非常感谢任何帮助，如果您可以在代码中添加注释，那将会很有帮助！
