what is wrong with this program?

Question

#include 
#include 
#include 

using namespace std;

int main() {
    string x;
    getline(cin,x);
    ofstream o(\"f:/demo         


        

Answer 1

You get exactly what you write: the binary raw value of a pointer to char...

#include 
#include 
#include 
using namespace std;

int main()
{
    string x;
    getline(cin,x);
    ofstream o("tester.txt");
    o << x;
    o.close();
}

If you insist on writing a buffer directly, you can use

o.write(x.c_str(), x.size());

PS A little attention to code formatting unclouds the mind
