c++读取txt文件
c++读取txt文件,txt文件大概是五个字符串一行，然后差不多一百行，怎么读取，并且存入一个string类的二维数组。 你这个问的就有点笼统...那我就给你贴一段书本上讲文件IO的代码吧...
// fileio.cpp -- saving to a file
#include <iostream> // not needed for many systems
#include <fstream>
#include <string>
int main()
{
using namespace std;
string filename;
cout << "Enter name for new file: ";
cin >> filename;
// create output stream object for new file and call it fout
ofstream fout(filename.c_str());
fout << "For your eyes only!\n"; // write to file
cout << "Enter your secret number: "; // write to screen
float secret;
cin >> secret;
fout << "Your secret number is " << secret << endl;
fout.close(); // close file
// create input stream object for new file and call it fin
ifstream fin(filename.c_str());
cout << "Here are the contents of " << filename << ":\n";
char ch;
while (fin.get(ch)) // read character from file and
cout << ch; // write it to screen
cout << "Done\n";
fin.close();
// std::cin.get();
// std::cin.get();
return 0;
}
