c语言编程实现linux cp命令

c语言编程实现Linux cp命令可以参考下面的代码：

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

int main(int argc, char *argv[]) {
    FILE *source, *destination;
    char ch;

    if (argc < 3) {
        printf("未传入源文件路径或者目标文件路径\n");
        exit(1);
    }

    source = fopen(argv[1], "r");
    if (source == NULL) {
        printf("打开源文件失败！\n");
        exit(1);
    }

    destination = fopen(argv[2], "w");
    if (destination == NULL) {
        printf("打开目标文件失败！\n");
        exit(1);
    }

    while ((ch = fgetc(source)) != EOF) {
        fputc(ch, destination);
    }

    printf("文件复制成功！\n");

    fclose(source);
    fclose(destination);

    return 0;
}
