请帮助，奇怪的行为 [英] Help please, strange behavior
问题描述
对不起，我把它发布在其他组合中，我没有看到它，而且这个组是最有效的，我把它转发到这里，对不起/>
mutliposting：
我用的是VC6，我有这个声明：
typedef struct tagTLimite {
double Debut;
double Fin;
} Limites;
typedef struct TagElemTab {
double NivY;
bool Existe;
std :: vector< LimitesPtLimites;
} ElemTabCont;
void myfunc（）
{
......
ElemTabCont * ContNonOrd; //轮廓非ordone
long nbNiveau =（yhi-ylo）/ stepY +1;
ContNonOrd = new ElemTabCont [nbNiveau];
......
}
i不知道为什么，nbNiveau等于（yhi-ylo）/ stepY，它没有't
+1 ????即使我放了：
ContNonOrd = new ElemTabCont [nbNiveau + 1]; ContNonOrd的大小=
nbNiveau ????
i''m sorry i posted this in other groupes, and i didn''t see it, and as
this group is most actif, i repost it here, and sorry for

}
i don''t know why,nbNiveau is equal to (yhi-ylo)/stepY, it didn''t
+1????and even if i put:
ContNonOrd = new ElemTabCont [nbNiveau+1]; the size of ContNonOrd =
nbNiveau????

''yhi'''''ylo''，''stepY''的类型是什么？他们的价值观是什么？
nbNiveau有什么价值？你有什么期望？
有可能你遇到了舍入（在
整数除法的情况下截断）并且添加1并不是做你需要的东西
它要做。
What is the type of ''yhi'', ''ylo'', ''stepY''? What are their values?
What value do you get in ''nbNiveau''? What did you expect?
It is possible that you''re encountering rounding (truncation in
case of integer division) and adding 1 doesn''t do what you need
it to do.
ContNonOrd = new ElemTabCont [nbNiveau];
.. ......

最后一句话超出了我。你是什么意思
ContNotOrd的大小？你怎么知道这个尺寸？怎么样？b $ b与你要求的尺寸不同？

请在通过电子邮件回复时删除大写''A'
我没有回复最热门的回复，请不要问
That last statement is beyond me. What do you mean by "the size of
ContNotOrd"? How the hell can you know the size? How can it be
different from the size you requested?

What is the type of ''yhi'', ''ylo'', ''stepY''? What are their values?
What value do you get in ''nbNiveau''? What did you expect
yhi，ylo，stepY是双打值：分别为16,0,0.1
我在nbNiveau得到160，我需要161.
？
y ylo, stepY are doubles values: 16, 0, 0.1 respectively
I get 160 in nbNiveau, and I need 161.

i只需在观察窗口中验证ContNotOrd [160]。
i just verify in watch window ContNotOrd[160].

除了Victor对你说，上面的定义是C-ish
而且并不是真的需要。它们应该是：
struct Limites {
double Debut;
double Fin;
} ;
struct ElemTabCont {
double NivY;
bool Existe;
std :: vector< ; LimitesPtLimites;
};
没有typedef或tag名字是必要的。
In addition to what Victor said to you, the definitions above are C-ish
and not really needed. They should be:
struct Limites {
double Debut;
double Fin;
};
struct ElemTabCont {
double NivY;
bool Existe;
std::vector<LimitesPtLimites;
};
No typedefs or "tag" names are necessary.
