c语言完成，直接写代码，不用解释：bmp格式两幅图像拼接，

以下是在 C 语言中拼接两幅 BMP 格式图像的示例代码：

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

#define WIDTH 512
#define HEIGHT 512

typedef unsigned char BYTE;
typedef unsigned short WORD;
typedef unsigned int DWORD;
typedef int LONG;

#pragma pack(push, 1)

// BMP 文件头
typedef struct
{
    WORD bfType;
    DWORD bfSize;
    WORD bfReserved1;
    WORD bfReserved2;
    DWORD bfOffBits;
} BITMAPFILEHEADER;

// BMP 信息头
typedef struct
{
    DWORD biSize;
    LONG biWidth;
    LONG biHeight;
    WORD biPlanes;
    WORD biBitCount;
    DWORD biCompression;
    DWORD biSizeImage;
    LONG biXPelsPerMeter;
    LONG biYPelsPerMeter;
    DWORD biClrUsed;
    DWORD biClrImportant;
} BITMAPINFOHEADER;

#pragma pack(pop)

int main()
{
    // 读取第一幅图像
    FILE* fp1 = fopen("image1.bmp", "rb");
    if (fp1 == NULL)
    {
        printf("Failed to open image1.bmp\n");
        return 1;
    }

    BITMAPFILEHEADER fileHeader1;
    BITMAPINFOHEADER infoHeader1;

    // 读取文件头
    fread(&fileHeader1, sizeof(BITMAPFILEHEADER), 1, fp1);
    // 读取信息头
    fread(&infoHeader1, sizeof(BITMAPINFOHEADER), 1, fp1);

    // 判断是否为 BMP 图像
    if (fileHeader1.bfType != 0x4D42)
    {
        printf("image1.bmp is not a BMP file\n");
        fclose(fp1);
        return 1;
    }

    // 分配存储图像数据的内存空间
    BYTE* data1 = (BYTE*)malloc(infoHeader1.biSizeImage);
    if (data1 == NULL)
    {
        printf("Failed to allocate memory for image1 data\n");
        fclose(fp1);
        return 1;
    }

    // 读取图像数据
    fseek(fp1, fileHeader1.bfOffBits, SEEK_SET);
    fread(data1, 1, infoHeader1.biSizeImage, fp1);
    fclose(fp1);
