#include <fstream>
#include <iostream>
using namespace std;
int main ( )
{
fstream f;
char cstring[256];
f.open ( "test.txt", ios::in );
short counter = 0;
while ( !f.eof ( ) )
{
f.getline ( cstring, sizeof ( cstring ) );
counter++;
cout << cstring << endl;
}
cout << "Anzahl der Zeilen:" <<counter << endl;
f.close ( );
system ( "PAUSE" );
}
我想用std :: string替换Cstring,但f.getline不将它作为参数。

成员函数getline()
仅适用于原始字符数组。 Modern C ++提供了可用于std::getline()
的免费函数std::string
:
#include <string>
std::string str;
while (std::getline(f, str)) {
}
