Linux平臺下提供了標準的Ｃ庫API實現對檔案的讀寫操作,同樣C++也提供了自身對檔案流操作的一些手段.雖然不知道以後會不會用到,但是瞭解一下是很有必要的.

原始碼:

#include <iostream>
#include <fstream>

using namespace std;

int main(void)
{       char filename1[256],filename2[256];
        cout<<"Input source file name:  ";
        cin>>filename1;
        cout<<"Input destination file name:  ";
        cin>>filename2;
        ifstream infile(filename1);
        ofstream outfile(filename2);
        char ch;
        while(infile.get(ch))
                outfile.put(ch);
        infile.close();
        outfile.close();

        return 0;
}
