打印出自身的c程序

简短的

#include<stdio.h>
main(){char *s="#include%cmain(){char *s=%c%s%c;printf(s,10,34,s,34);}";printf(s,10,34,s,34);}

可读性佳的

#include<stdio.h>
main(){
    char *s="#include%cmain(){%c%cchar *s=%c%s%c;%c%cprintf(s,10,10,9,34,s,34,10,9,10);%c}";
    printf(s,10,10,9,34,s,34,10,9,10);
}

//Copyright (c) LeafCore
#include<stdio.h>
void main() {
    char *s="//Copyright (c) LeafCore%c#include%cvoid main() {%c%cchar *s=%c%s%c;%c%cprintf(s,10,10,10,9,34,s,34,10,9,10);%c}";
    printf(s,10,10,10,9,34,s,34,10,9,10);
}

What a fantasy!
可执行文件生成自身的源文件

//Copyright (c) LeafCore
#include<stdio.h>
main(){
    FILE *fp=fopen("file.c","w");
    char *s="//Copyright (c) LeafCore%c#include%cmain(){%c%cFILE *fp=fopen(%cfile.c%c,%cw%c);%c%cchar *s=%c%s%c;%c%cfprintf(fp,s,10,10,10,9,34,34,34,34,10,9,34,s,34,10,9,10,9,10,9,10);%c%cfclose(fp);%c%creturn 0;%c}";
    fprintf(fp,s,10,10,10,9,34,34,34,34,10,9,34,s,34,10,9,10,9,10,9,10);
    fclose(fp);
    return 0;
}

运行生成的可执行文件，可生成自身的源文件。
