我试图将2个文件复制到1个文件,如ID1.name1.ID2.name2.但我不能这样做......我应该如何从每个文件中复制每一行.
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream file1("ID.txt");
ifstream file2("fullname.txt");
ofstream file4("test.txt");
string x,y;
while (file1 >> x )
{
file4 << x <<" . ";
while (file2 >> y)
{
file4 << y <<" . "<< endl;
}
}
}
