将以上代码保存为read.h,使用时只需#include "read.h"即可(注意:一定要在相同目录下!!!)
支持读入整数int x=readint<int>(); or long long x=readint<long long>(); or long x=readint<long>(); or short x=readint<short>();
如果要提交题目怎么办??
答:取出你要用的部分即可。
读入整数:
void pushint(int &index,int pushindex){ index*=10; index+=pushindex; } template<typename intype> intype readint(){ char c; bool fs=false; c=getchar(); intype finally=0; if(c=='-'){ fs=true; } else{ if(c<'0'||c>'9'){ return finally; } else{ push(finally,c-'0'); } } while(1){ c=getchar(); if(c<'0'||c>'9'){ break; } else{ push(finally,c-'0'); } } return (fs?(0-finally):finally); }
读入字符:
#define readchar getchar
