用于在正数之前排列负数的C ++的向量代码。 [英] Vector code for C++ to arrange negative numbers before positive numbers.
问题描述
写一个函数
void arrangeVector（vector< int>& V）
来计算以下任务。
函数re - 排列向量V的元素，使得数组中的所有负数出现在所有非负整数之前。
注意，向量不需要排序，只有负数必须首先出现。
你不应该使用辅助数组或向量来完成这项任务。
注意： -
你应该只需要
写这个函数
不要写一个
主要功能。
如果你这样做，你的代码将无法编译，并且将被授予零美元。
此外，
不会更改名称功能
并填写你的代码，只写在提供的
函数体中。
另外，你不需要任何来自用户的输入，不应该打印任何东西。所以，
不要使用任何
cin
或
cout
语句。
我尝试了什么：
#include< iostream> ;
#include< vector>
使用命名空间std;
void arrangeVector（vector< int>& V）{
//完成此功能。不要写主要
//不要更改功能名称
//在下面写下你的代码
}
Write a function
void arrangeVector(vector<int> & V)
to compute the following task.
The function re-arranges the elements of the vector V such that all negative numbers in
the array appear before all the non-negative integers.
Note that the vector need not be sorted, only the negative numbers must appear first.
You should not use a secondary array or vector to accomplish this task.
NOTE:-
You should
ONLY
write this function
Do not write a
MAIN FUNCTION.
If you do so, your code will not compile and will be
awarded a zero.
Also,
do not change the name of the function
and fill in your code, only write in the
function body provided.
Also, you do not need to take any input from the user and should not print anything. So, do
not use any
cin
or
cout
statements.
What I have tried:
#include <iostream>
#include <vector>
using namespace std;
void arrangeVector(vector<int> & V){
// Complete the function. DO NOT WRITE A MAIN
// DO NOT CHANGE THE FUNCTION NAME
// Write your code below
}
推荐答案
我们不做你的功课：这是有原因的。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。但是我们不会为你做这一切！
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!
所以，你没有尝试自己解决问题，你毫无疑问，你只是想让我们做你的HomeWork。
HomeWork问题是你在现实生活中必须解决的问题的简化版本，他们的目的是学习和练习。
我们不做你的HomeWork。
HomeWork不会测试你乞求别人做你的工作的技能，它会让你思考和帮助您的老师会检查您对所学课程的理解以及您应用这些课程时遇到的问题。
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，请显示您的代码并解释这个问题，我们可能会提供帮助。
作为程序员，您的工作是创建算法解决特定问题，你不能依赖别人永远为你做，所以有一段时间你必须学会如何。而且越快越好。
当你要求解决方案时，就像试图通过培训其他人来学习开车一样。
创建算法基本上是找到数学并做出必要的调整以适应你的实际问题。
So, you show no attempt to solve the problem yourself, you have no question, you just want us to do your HomeWork.
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose is learning and practicing.
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.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
不要写
主要功能。
Do not write a
MAIN FUNCTION.
建议：编写一个主函数，这样你就可以编译代码并检查它的功能。
main函数调用'arrangeVector'和一些样本数据。
然后在提交之前删除main函数。
Advice: write a main function, so you can compile the code and check what it does.
the main function call 'arrangeVector' with some sample data.
Then remove the main function before submitting.
这个功课很简单。想想像
这样的小步骤1.找到小于零的元素
2.将元素移动到向量的开头
从一些矢量教程中学习。
提示：制作一个示例项目，其中包含您的解决方案代码文件。
This homework is so simple. Think about tiny steps like
1. find elements which are less than zero
2. move the element to the start of the vector
Learn from some vector tutorial.
tip: make a sample project in which you include your solution code file.
