Thread: [Dev-C++] writing to a file

Hi everyone!,

I have this code to overwrite the high score in the highscore.txt file 
in a RPG game that I'm working on for class.  I keep getting a 'outfile 
undeclared' fist use this function when it gets to the bolded open file 
for output part.  I included #include<fstream> at the beginning.  Any 
idea's??

Also, I tried putting curley brakets around after the if statement since 
it's a compound statement block, but then I get this error from  dev c++

empty character constant

thx!

//Write player's high score if greater then score in txt file
 
//declare file pointer for input
   ifstream infile;


//declare variables
  string fileName = "";
  int highScore = 0;
 
 
//Open file for input
  infile.open("highscore.txt", ios::in);
 
//read in data
  getline(infile, fileName);
  infile>>highScore;
 
//Close file
  infile.close();
 
if (playerScore > highScore)
//declare file pointer for input
  ofstream outfile;
 
*//Open file for output
  outfile.open("highscore.txt", ios::out);*
 
//write data
  outfile<<playerName<<playerScore<<endl;

//close file
  outfile.close();

if (playerScore > highScore)
    ofstream outfile;

is equivalent to

if (playerScore > highScore)
{
    ofstream outfile;
}

so there is no outfile variable after the if statement

you did something wrong, this is correct solution:

if (playerScore > highScore)
{
//declare file pointer for input
   ofstream outfile;

//Open file for output
   outfile.open("highscore.txt", ios::out);

//write data
   outfile<<playerName<<playerScore<<endl;

//close file
   outfile.close();
}
