矢量类字符串排序 [英] vector class string sort
问题描述
你好，
我在我需要做的事情上遇到了一些问题。
我正在使用一个向量来存储一个数组一个特定的类对象已满
的数据。
class part_info
{
public：
string part_no;
string raw_qty;
int qty;
int ref;
part_info（）：part_no（""），raw_qty（""），qty（0），ref（0）{}
part_info（string NewPartNo，string NewRawQty，int NewQty，int
NewRef）：part_no（NewPartNo），raw_qty（NewRawQty），qty（NewQty），
ref（NewRef）{}
};
.....
无效设置{
NAMEVECTOR theVector;
NAMEVECTOR :: iterator theIterator;
.....
//向我的向量添加数据集
theVector.push_back（part_info（part_no，raw_qty，qty，ref））;
}
我已经完成了将数据添加到我的数据中vector我希望能够
按part_no排序。
我已经看过了覆盖运算符<然后使用std :: sort，
但是我正在编译错误，而我理解了基本的
发生了什么，我必须遗漏一些东西。
有人可以帮我这个吗？
谢谢

我们如何在没有错误消息和源代码的情况下为您提供帮助？

typedef vector< part_infoNAMEVECTOR;
重载< partinfo类中的运算符（比较部分号）。然后
排序成员应该为你排序向量。
你得到了什么确切的编译错误？

当然。你对被覆盖的运营商的定义在哪里？（）？

Hello,
I''m having some problems wrapping my head around what I need to do.
I''m using a vector to store an array of a specific class object full
of data.
class part_info
{
public:
string part_no;
string raw_qty;
int qty;
int ref;
part_info() : part_no(" "), raw_qty(" "), qty(0), ref(0) {}
part_info(string NewPartNo, string NewRawQty, int NewQty, int
NewRef) : part_no(NewPartNo), raw_qty(NewRawQty), qty(NewQty),
ref(NewRef) {}
};
.....
void setup {
NAMEVECTOR theVector;
NAMEVECTOR::iterator theIterator;
.....
//add a dataset to my vector
theVector.push_back(part_info(part_no,raw_qty,qty, ref));
}
When I''m finished adding my data to my vector I want to be able to
sort it by part_no.
I''ve looked at overriding the operator < and then using the std::sort,
but I''m getting compiling errors and while I understand the basic of
what is going on I must be missing something.
Could someone please help me with this?
Thanks

How can we help you without the error messages and the source code?

typedef vector<part_infoNAMEVECTOR;Overload < operator in the partinfo class (compare on part num). The
sort member should then sort the vector for you.
What exact compile errors are you getting?
