//用可变参数列表实现printf函数#include <stdio.h>#include <stdarg.h>void my_printf(const char *str,...){va_list fun;va_start (fun,str);while(*str!=0){if(*str=='c'){putchar(va_arg(fun,char ));}if(*str=='s'){puts(va_arg(fun,char *));}str++;}va_end(fun);}int main (){my_printf("ccss",'a','j',"sas","awdaf");return 0;}
