问题描述
#pragmaonce#include"assert.h"classstring{public://构造函数string();//string(charc);string(unsigned);unsignedlength()const;private:unsignedbuflen;char*buffer;unsignedcstrLen(constcharstr[]);};string::string(){buflen=1;buffer=newchar[buflen];assert(buffer!=0);buffer[0]='';}string::string(unsignedsize){assert(size>=0);//设置数据域buflen=1+size;buffer=newchar[buflen];assert(buffer!=0);//初始化for(unsignedi=0;i<buflen;i++)buffer[i]='';}string::~string(){delete[]buffer;buflen=0;}unsignedstring::length()const{returncstrLen(buffer);}unsignedstring::cstrLen(constrcharstr[]){unsignedi=0;while(str[i]!='')i++;returni;}int_tmain(intargc,_TCHAR*argv[]){unsignedsize=20;stringa;stringb(size);cout<<"abuflen="<<a.length()<<endl;//cout<<"bbuflen="<<b.length()<<endl;return0;}在运行时,如果只是stringa,然后输入长度,是可以的.但是如果增加unsignedsize=20;stringb(size);就会出现如下,请教高手了!错误1errorC2664:“std::basic_string<_Elem,_Traits,_Ax>::basic_string(std::basic_string<_Elem,_Traits,_Ax>::_Has_debug_it)”:不能将参数1从“unsignedint”转换为“std::basic_string<_Elem,_Traits,_Ax>::_Has_debug_it”c:userslzshendocumentsvisualstudio2008projectsappstringappstringappstring.cpp14appString
解决方案
解决方案二：
和c++库的string冲突了,要么带好命名空间,要么就不要叫string了
