下面的是代码
求指点。。
#include<iostream>
#include<fstream>
#include<string>
using namespace std;
//subs1是要查找的字符串
//subs2 是要将subs1从text中替换掉的字符串
void replace(wstring &text, const wstring &subs1, const wstring &subs2)

wcout<<subs1<<" "<<subs1.size()<<endl;
wcout<<subs2<<" "<<subs2.size()<<endl;

cout<<beg<<endl;
if(beg >= text.size())
{
cout<<"不能匹配"<<endl;
return;
}
text.erase(beg, subs1.size());
text.insert(beg, subs2);
/*while(beg < text.size())
{
beg = text.find(subs1);
text.erase(beg, subs1.size());
text.insert(beg, subs2);
}*/
}
//从file中读取文本，然后将str给初始化。

}
//将替换好的text再重新输出到一个文件中
