ofstream fts1("d:/1.txt")

int a=5

fts1<<a<<endl

return 0

}

#include <fstream>

#include <string>

using namespace std

class YourType

{

public:

YourType(string a, string b, string c, int d):a_(a), b_(b), c_(c), d_(d){}

friend ostream &operator<<(ostream&os, const YourType &t)

private:

string a_

string b_

string c_

intd_

}

ostream &operator<<(ostream&os, const YourType &t)

{

os<<t.a_<<" "<<t.b_<<" "<<t.c_<<启者悄" "<悄渣<t.d_

return os

}

int main()

{

ofstream fout("stock.txt")

YourType a("SHTN", "JEHRL", "JFDF", 32333)

fout<<a<<endl

//嫌举 others

fout.close()

return 0
