C ++如何让计算机知道0100是100？ [英] C++ How to let the computer know that 0100 is 100?
问题描述
作为初学者，我正在研究计算电话费的项目。谢谢大家，我的节目很棒..但是我又遇到了另一个问题，因为我的老师试图欺骗我这个..
他输入0100，他没有输入100所以这个程序'的计算是完全错误的。
我试图使用if语句，它在输入0100时有效，但在输入1000时它不起作用，它得到了一些错误的计算..每次我在时间之前输入0（如0800），程序无法正常工作......我不知道为什么!!
你能帮我解决这个问题吗？我很困惑。
As a beginner, I am working on a project that calculates the telephone bill. Thank you all, my program is great.. but I got another problem because my teacher was trying to trick me with this..
that he enter 0100, he didn''t enter 100 so the program''s calculation is totally wrong.
I have tried to use if statements, it works when entering 0100 but it does not work when entering 1000, it got some wrong calculation.. Everytime I enter 0 before the time (like 0800) the program doesn''t work properly.. I don''t know why!!
Can you guys help me out with this? I am so confused.

0100，或任何其他带有前导零的数字，被解释为八进制数而不是但是，如果你的教授这样做并且没有告诉你关于八进制的信息，他就是一个混蛋。
0100, or any other number with a leading zero, is interpreted as an octal number rather than a number in base 10. Frankly, if your professor is doing that and hasn''t told you about octal, he''s being a bit of a jerk.
