能输出自身代码的程序_自行码输出-优快云博客

博客给出不借助文件操作输出程序源代码的条件，并展示了C语言实现该功能的程序代码。代码通过特定字符数组和循环输出自身源代码。同时提到，不仅C语言能实现，Java也具备此能力，鼓励读者自行思考实现方式。

条件：不借助任何文件操作，输出程序的source code.

程序：

#include <stdio.h>
char c[] = {0x7d,0x3b,0xa,0x69,0x6e,0x74,0x20,0x6d,0x61,0x69,0x6e,0x28,0x29,0xa,0x7b,0xa,0x20,0x20,0x20,0x20,0x70,0x72,0x69,0x6e,0x74,0x66,0x28,0x22,0x23,0x69,0x6e,0x63,0x6c,0x75,0x64,0x65,0x20,0x3c,0x73,0x74,0x64,0x69,0x6f,0x2e,0x68,0x3e,0x5c,0x6e,0x63,0x68,0x61,0x72,0x20,0x63,0x5b,0x5d,0x20,0x3d,0x20,0x7b,0x22,0x29,0x3b,0xa,0x20,0x20,0x20,0x20,0x66,0x6f,0x72,0x28,0x69,0x6e,0x74,0x20,0x69,0x3d,0x30,0x3b,0x69,0x3c,0x73,0x69,0x7a,0x65,0x6f,0x66,0x28,0x63,0x29,0x3b,0x2b,0x2b,0x69,0x29,0xa,0x20,0x20,0x20,0x20,0x7b,0xa,0x20,0x20,0x20,0x20,0x20,0x20,0x20,0x20,0x70,0x72,0x69,0x6e,0x74,0x66,0x28,0x22,0x30,0x78,0x25,0x78,0x2c,0x22,0x2c,0x63,0x5b,0x69,0x5d,0x29,0x3b,0xa,0x20,0x20,0x20,0x20,0x7d,0xa,0x20,0x20,0x20,0x20,0x70,0x72,0x69,0x6e,0x74,0x66,0x28,0x22,0x25,0x73,0x22,0x2c,0x63,0x29,0x3b,0xa,0x20,0x20,0x20,0x20,0x72,0x65,0x74,0x75,0x72,0x6e,0x20,0x30,0x3b,0xa,0x7d,};
int main()
{
    printf("#include <stdio.h>/nchar c[] = {");
    for(int i=0;i<sizeof(c);++i)
    {
        printf("0x%x,",c[i]);
    }
    printf("%s",c);
    return 0;
}

至于怎么做到的，大家可以自己琢磨

不过不要以为只有C能做到，java也可以哦
