C++文件读写

示例代码如下：

#include<iostream.h>
#include<iomanip.h>
#include<fstream.h>
int main()
{
 ofstream outFile("1.txt");
 ifstream inFile("1.txt");
 char buf[]="wangkechuang";
 char buf1[20]="";
 outFile.write(buf,sizeof("wangkechuang"));
// outFile<<"姓名:"<<"wangkechuang";
 outFile.close();

 inFile.read(buf1,sizeof("wangkechuang"));
 cout<<buf1<<endl;
 return 0;
}
