C ++将数组拆分成块 [英] C++ split array into blocks

问题描述

大家好我怎么能把一个数组拆分成块。例如给定一个大小为4x4的数组将数组除以2x2的块，然后数组的大小为4x4，这样就会有四个2x2的块。 />


在这种情况下，块大小为2;

Hello every one how can i split an array into blocks.For example Given an array of size 4x4 divide the array by blocks of 2x2 and then the size of the array is 4x4 so there will be four blocks of 2x2.

In this case block size is 2;

             Block 1      Block2
0 1 0 0       0 1         0 0
1 1 1 0 - >   1 1         1 0
0 0 0 0 - >
1 1 0 0       Block 3      Block4
              0 0          0 0
              1 1          0 0

我想要这样的东西。任何帮助将不胜感激

推荐答案

怎么样：

How about:

int block[4][4] =
{
    { 0,1,0,0 },
    { 1,1,1,0 },
    { 0,0,0,0 },
    { 1,1,0,0 }
};

int block1[2][2];
int block2[2][2];
int block3[2][2];
int block4[2][2];

for (int i = 0; i < 2; i++)
{
    for (int j = 0; j < 2; j++)
    {
        block1[i][j] = block[i][j];
        block2[i][j] = block[i][j+2];
        block3[i][j] = block[i+2][j];
        block4[i][j] = block[i+2][j+2];
    }
}
