编写了一段程序，想把一个文件中的数据重新写入另一个文件，数据存放的顺序有所不同，程序编译没有什么问题，但一运行就有问题，请大家帮忙看看，非常感谢！

#include <stdio.h>
#include <stdlib.h>

#define WIDTH 720
#define HEIGHT 576

void main()
{
    FILE *fp1, *fp2;
    int *frame;
    int *pointer_Y, *pointer_Cb, *pointer_Cr;
    int frameSize, Y_size, Cb_size, Cr_size;
    int fth;
    int pixel;
    int i_Y=0, i_Cb=0, i_Cr=0;
    int buffer;
    frameSize = 2*WIDTH*HEIGHT;
    Y_size = frameSize/2;
    Cb_size = Y_size/2;
    Cr_size = Cb_size;

    pointer_Y = malloc(Y_size);
    pointer_Cb = malloc(Cb_size);
    pointer_Cr = malloc(Cr_size);
    if((fp1=fopen("original.yuv","rb")) == NULL)
        printf("Original file open error.\n");
    if((fp2=fopen("target.yuv","wb")) == NULL)
        printf("Target file open error.\n");
    frame = malloc(frameSize);
    for(fth=0;fth<100;fth++)
    {
        fread(frame,1,frameSize,fp1);
        for(pixel=0;pixel<frameSize;pixel++)
        {
            buffer = pixel%4;
            switch(buffer)
            {
            case 0:
                {
                    *(pointer_Cb+i_Cb) = *(frame+pixel);
                    i_Cb++;
                }
            case 1:
                {
                    *(pointer_Y+i_Y) = *(frame+pixel);
                    i_Y++;
                }
            case 2:
                {
                    *(pointer_Cr+i_Cr) = *(frame+pixel);
                    i_Cr++;
                }
            case 3:
                {
                    *(pointer_Y+i_Y) = *(frame+pixel);
                    i_Y++;
                }
            }
        }
        fwrite(pointer_Y,1,Y_size,fp2);
        fwrite(pointer_Cb,1,Cb_size,fp2);
        fwrite(pointer_Cr,1,Cr_size,fp2);
    }
    fclose(fp1);
    fclose(fp2);
}

顶一下，请大家多多指教

顶一顶

好复杂哦,有点注释就好了,让我们新手也学习学习.

期待高人出现！！
