Linux 用fread fwrite 复制一张图片，c语言

可以使用以下代码复制一张图片：

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

#define BUFFER_SIZE 1024

int main() {
    FILE *source_file, *target_file;
    char buffer[BUFFER_SIZE];

    source_file = fopen("source_image.jpg", "rb");
    if (source_file == NULL) {
        printf("Failed to open source file.");
        return 1;
    }

    target_file = fopen("target_image.jpg", "wb");
    if (target_file == NULL) {
        printf("Failed to open target file.");
        return 1;
    }

    while (!feof(source_file)) {
        size_t bytes_read = fread(buffer, 1, BUFFER_SIZE, source_file);
        fwrite(buffer, 1, bytes_read, target_file);
    }

    fclose(source_file);
    fclose(target_file);

    return 0;
}

请将代码中的 "source_image.jpg" 和 "target_image.jpg" 替换为你实际的文件名，并确保目标文件的目录已存在。
