类矩阵问题 [英] Classes Matrix question

问题描述

大家好。我正在编写一个使用名为matrix的类的程序。我编写了所有不同的函数，构造函数等。


当我运行程序时，我收到构造函数，我将其置于构造函数中，然后程序崩溃。我不知道我的问题在哪里。


矩阵的大小为2x2到10x10，它必须是正方形。


下面是代码：

Hello everyone. I''m writing a program which uses a class called matrix. I have written all of the different functions, constructor, etc.

When I run the program I receive "Constructor", which I placed in the constructor, and then the program crashes. I have no clue where my problem is.

The matrix is for size 2x2 up to 10x10, and it must be square.

Below is the code:

展开 | 选择 | Wrap | 行号

推荐答案

你的循环都有一个错误。当数组的最大尺寸

等于10时，有效索引值为0,1,2,3,4,5,6,7,8和9（计算它们：

有10个不同的索引值）。因此你的循环应该都有一个

终止条件，例如：

Your loops all have an off by one error. When the maximum dimension of an array
equals 10, valid index values are 0, 1, 2, 3, 4, 5, 6 , 7, 8, and 9 (count them:
there are 10 different index values). Therefore your loops should all have a
terminating condition such as:

< span class =codeLinkonclick =Blur（this，this.parentNode.parentNode，getChildren（this），true）;>展开 | 选择 | Wrap | 行号

再次回到我的救援行动中，何塞哈？


我明白你在说什么，这是对的......我没想到我什么时候把它们做得比等于10.程序仍然崩溃，所以函数不会超出范围（或者不管它的名称）。

Back to my rescue again hun JosAH?

I understand what you''re saying, and that is right...I wasn''t thinking when I made them less than or equal to 10. The program still crashes, so the functions aren''t going out of scope (or whatever it''s called).

再次回到我的救援胡约什啊？

我仔细看了你的代码：看看你的ctor中的内循环：

它增加''我'而不是''j''它会射击你为此而努力;-)


亲切的问候，


Jos

I took a bit closer look at your code: have a look at the inner loop in your ctor:
it increments ''i'' instead of ''j'' and it will shoot you in your foot for it ;-)

kind regards,
