I tried to read a file using the following code, but it kept saying it couldn't open the file. no idea where I missed. Could someone debug it, thanks ahead.
CODE

#include <iostream>
#include <fstream>
using namespace std;


int main()
{
  int container[2000];
  fstream file_open("c:\\test_file.txt",ios::in);
  while(file_open >> container)
    cout << container;

  file_open.close();

  return 0;
}

HI Jay

at first glance the code appears ok... best guess is the file isn't located in the root of the C drive. Check the location of the file.

the fstream class does not contain a function that overloads the >> operator which takes an integer array on the right hand side.

Rename int to char.
Your code should look like this.
CODE

#include <iostream>
#include <fstream>
using namespace std;


int main()
{
char container[2000];
fstream file_open("c:\\test_file.txt",ios::in);
while(file_open >> container)
cout << container;

file_open.close();

return 0;
}


The code compiles, and runs perfectly well. smile.gif
