对文件操作时有时获得文件的大小时必要的.
下面是获得其大小小的较简单方法.
#include<io.h> //C语言头文件
#include<iostream> //for system();
using namespace std;
int main()
{
int handle;
handle = open("test.txt", 0x0100); //open file for read
long length = filelength(handle); //get length of file
cout<<"file length in bytes:"<<length<<endl;
close(handle);
system("pause");
return 0;
}
