从 .txt 文件读取到 C++ 中的二维数组

2021-12-21 00:00:00 input file arrays c++

所以要么我是个彻头彻尾的白痴，这正直盯着我看，但我似乎无法在谷歌或这里找到任何我能理解的资源.

So either I'm a complete idiot and this is staring me right in the face, but I just can't seem to find any resources I can understand on google, or here.

我有一个包含多行整数的文本文件，每个整数用空格分隔，我想将这些整数读入一个数组，其中每一行是数组的第一维，每个整数在那条线上被保??存到第二维中.

I've got a text file which contains several lines of integers, each integer is separated by a space, I want to read these integers into an array, where each new line is the first dimension of the array, and every integer on that line is saved into the second dimension.

可能用了最糟糕的术语来解释，抱歉.

Probably used the worst terminology to explain that, sorry.

我的文本文件如下所示:

My text file looks something like this:

100 200 300 400 500
101 202 303 404 505
111 222 333 444 555

我希望得到的数组是这样的:

And I want the resulting array to be something like this:

int myArray[3][5] = {{100, 200, 300, 400, 500},
                     {101, 202, 303, 404, 505},
                     {111, 222, 333, 444, 555}};

推荐答案

我相信

istream inputStream;
int myArray[3][5];
for(int i = 0; i < 3; i++)
    for(int j = 0; j < 5; j++)
        istream >> myArray[i][j];

应该做你需要的.
