new line

Hi, I have a code where I scan a file, but I want to scan the entire document, not only the first line. The code I have is:

Code:

---

ifstream c_file (place);               
c_file.getline(info, 300);       
c_file.close();

---

where info is the information I want to scan, and place is the location of the file.

I don't think getline will get the new line, is there a way of including a newline in scanning?

doesn't get line do exactly what it says (get a line),,, if you want to put the whole file into a buffer why don't you check out filebuf functions......................................... .....then you can output the whole thing onto the console......or do tring searches (whateva)

I was advised not to use getline (Dont know why).

Heres an alternative:

Code:

---


int loadtomemory(string IFpath) {
 #define maxN 4999
 #define maxL 100
  char memmap[5000];
 int x, line;

 ifstream file_in(IFpath.c_str(), ios::nocreate);

 if(!file_in)
  cout << "Could not open file.";

 for(x=0; x <= maxN; x++) {
  if(++line == maxL)
  break;
  file_in.get(memmap[x]);
  if(isrestricted(memmap[x] == 1)
  break;
 }

 file_in.close();
 return 0;
}

int isrestricted(char res[]) {
 char restricted[] = "restricted"; //Put restricted characters here. Add space as needed.
 int x;

 for(x=0; x <= (sizeof(restricted[]) / sizeof restricted[0]); x++) //Not sure if this'll work. Could any pros correct this?
 if(res == restricted[x])
  return 1;
 
 return 0;
}

Some of that code might not work sence its not compiled, but you get the idea?

Well, how about a loop. Calling getline in the loop will allow you to read through the whole file. The getline function will read a newline character from the stream but will not store it in the buffer.

If you want to read the entire file in one go without a loop you can use this:

Code:

---

ifstream c_file(place);
stringstream sstr;
string info;

if( c_file.is_open() )
{
    sstr << c_file.rdbuf();  // Read entire file into stringstream
    info = sstr.str();      // Convert stringstream into string
    // Do whatever you want with the string "info".
}

---

The ifstream object's destructor will close the file for you.
