如何将二维数组作为参数发送给函数 [英] how to send 2 dimension array as a parameter to a function

问题描述

我无法将二维数组发送给函数

i can not send 2 dimension array to a function

void fun(int **x);
int _tmain(int argc, _TCHAR* argv[])
{
    int x[5][6];

    for(i=0;i<5;i++)
        for(j=0;j<6;j++)
            x[i][j]=i+j;

        for(i=0;i<5;i++)
        for(j=0;j<6;j++)
            cout<<"x[i][j]="<<x[i][j]<<endl;

        fun(&(x);<-----Error

    return 0;
}
void fun(int **x)
{

推荐答案

请参阅此 [ ^ ]和^ ]来自 comp.lang.c [ std :: vector [

Please see this[^] and this[^] question from comp.lang.c[^].
The answers to these two questions contain all you need. :)

BTW: Your question is tagged as C++ not C. Above links will solve the problem in your C - style code.
If you want to change your code to C++ - style, then you can replace your two dimensional integer array with
std::vector< std::vector<int> > (see std::vector[^]) and pass this vector by reference to your function. :)

您的函数应如下所示:

Your function should be like this:

void fun(int x[][6])
{
}

并且您会这样称呼它:

and you would call it like this:

int x[5][6];
fun(x);

奇怪的是:

Oddly enough:

int _tmain(int argc, _TCHAR* argv[])
{
  // argv points to an array of c style strings.
  // a c style string is a character array where the 
  // last character is set to '\x0'.

  // You had the required declaration for 2 dimensional arrays 
  // right in front of you all the time.
}
