Problem with file by using fstream library and print on screen? - c++

Question

I am trying to print the data located in the weapon.obj file, but it's not working.
Compiler Error: error: no matching function for call to
'getline(std::ifstream&)'|
Code:
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ofstream render_weapon_OBJ ("weapon.obj");
render_weapon_OBJ << ("Weapon Names");
render_weapon_OBJ.close();
ifstream execute_weapon_OBJ ("weapon.obj");
while (getline(execute_weapon_OBJ))
{
cout << execute_weapon_OBJ << '\n';
}
execute_weapon_OBJ.close();
}

Answer 1

You must specify where to read the data and use that for printing.
#include <iostream>
#include <fstream>
#include <string> // add this to use std::string
using namespace std;
int main()
{
ofstream render_weapon_OBJ ("weapon.obj");
render_weapon_OBJ << ("Weapon Names");
render_weapon_OBJ.close();
ifstream execute_weapon_OBJ ("weapon.obj");
string weapon; // add this for read buffer
while (getline(execute_weapon_OBJ, weapon)) // add where to read
{
cout << weapon << '\n'; // print what was read instead of the stream
}
execute_weapon_OBJ.close();
}

Answer 2

May be this is the solution you are looking for
You need a variable to store the line read from the file and you need to print the variable not the variable used to initialize the file stream.
The error is in the while loop[The new code is below]
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
string line;
ofstream render_weapon_OBJ ("weapon.obj");
render_weapon_OBJ << ("Weapon Names");
render_weapon_OBJ.close();
ifstream execute_weapon_OBJ ("weapon.obj");
while(getline(execute_weapon_OBJ,line))
{
cout << line << '\n';
}
execute_weapon_OBJ.close();
}
