自复制程序

好久没写博客了，CSDN似乎更新了代码高亮代码，贴段代码试试吧。

 

有次部门开会，我能力差，听不懂，又太无聊，尝试写了个自复制程序，C版本的。

#include <stdio.h>#include <string.h>#define MODE_NORMAL 0#define MODE_LITER 1void myprint(char* str, int mode, int len){switch (mode) {case MODE_NORMAL:if (len < 0)printf("%s", str);else {int i;for (i = 0; i < len; i++)putchar(str[i]);}break;case MODE_LITER:if (len < 0)len = strlen(str);{int i;putchar('/"');for (i = 0; i < len; i++) {if (str[i] == '/n') {printf("//n"); continue;}if (str[i] == '/"') {printf("///""); continue;}if (str[i] == '//') {printf("////"); continue;}putchar(str[i]);}putchar('/"');}break;}}char* p = "#include <stdio.h>/n#include <string.h>/n/n#define MODE_NORMAL 0/n#define MODE_LITER 1/n/nvoid myprint(char* str, int mode, int len)/n{/nswitch (mode) {/ncase MODE_NORMAL:/nif (len < 0)/nprintf(/"%s/", str);/nelse {/nint i;/nfor (i = 0; i < len; i++)/nputchar(str[i]);/n}/nbreak;/ncase MODE_LITER:/nif (len < 0)/nlen = strlen(str);/n{/nint i;/nputchar('///"');/nfor (i = 0; i < len; i++) {/nif (str[i] == '//n') {printf(/"////n/"); continue;}/nif (str[i] == '///"') {printf(/"///////"/"); continue;}/nif (str[i] == '////') {printf(/"/////////"); continue;}/nputchar(str[i]);/n}/nputchar('///"');/n}/nbreak;/n}/n}/n/nint main(int argc, char** argv)/n{/nmyprint(p, MODE_NORMAL, 620);/nmyprint(/"char* p = /", MODE_NORMAL, -1);/nmyprint(p, MODE_LITER, -1);/nputchar(';');/nmyprint(p+618, MODE_NORMAL, -1);/nreturn 0;/n}/n";int main(int argc, char** argv){myprint(p, MODE_NORMAL, 620);myprint("char* p = ", MODE_NORMAL, -1);myprint(p, MODE_LITER, -1);putchar(';');myprint(p+618, MODE_NORMAL, -1);return 0;}
