编写一个c ++程序来查找给定数字是否存在于给定的整数内。



我尝试过：

What I have tried:

推荐答案

你必须迭代搜索给定的整数数字。

基本上有两种方法：

• 使用％和 / 运算符检查最后一位数，然后将数字除以 10 。
• 使用库函数将整数转换为字符串，然后遍历字符串字符。

You have to iterate over all the integer digits, searching for the given one.
There are basically two approaches:

• Use the % and / operators to check last digit and then divide the number by 10.
• Use a library function to transform the integer to a string and then iterate over the string characters.

我们不做你的功课：设置是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！



如果遇到具体问题，请询问相关问题，我们会尽力提供帮助。但是我们不打算为你做这一切！

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!

引用：

write a c++ program to find whether the given digit exists within a given integer.

您没有说明任何问题或提出任何问题。



想想问题，你已经知道怎么做了，它和时间转换一样。

你知道如何将36小时转换为天和小时，它是1天12小时。

您知道如何将90分钟转换为小时和分钟，它是1小时30分钟。

您的问题是将1234转换为数十和单位，它是123和4个单位。 4个单位是您要测试的第一个数字。你只需要在123上重复相同的操作来获得第二个数字，依此类推......



我们不做你的HomeWork。

HomeWork不会在乞求别人做你的工作时测试你的技能，它会让你思考并帮助你的老师检查你对你所学课程的理解以及你在申请时遇到的问题他们。

你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。

你的任何失败都会帮助你了解什么有效，什么无效，被称为'试错'学习。

所以，试一试，重读课程并开始工作。如果您遇到特定问题，请展示您的代码并解释这个问题，我们可能会提供帮助。

You didn't stated any problem or asked any question.

Think about the problem, you already know how to do it, it works the same as time conversions.
You know how to convert 36 hours to days and hours, it is 1 day and 12 hours.
You know how to convert 90 minutes to hours and minutes, it is 1 hour and 30 minutes.
Your problem is about conversion of 1234 to tens and units, it is 123 tens and 4 units. The 4 units is the first digit you want to test. you just have to repeat the same operation on 123 to get a second digit, and so on ...

We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
