Loading and Saving from a file c++ highscore function
<p>I have a game that I have created. I want to implement a function that loads and saves  high scores. At first when there is no text file (in my case <code>highscore.txt</code>), once created I want to print 0 to the file. If it is there on load I want it to load the highscore from the previous playing of the game. How would I go about this?</p>

<p>Here is my code:</p>

<pre><code>void filewrite(){

    int n;

    FILE *FPtr;
    FPtr = fopen("highscore.txt","w+");//open file
    if (FPtr == NULL){
    fprintf (FPtr, "%d" , highscore);
    rewind(FPtr);
    }
    fscanf(FPtr,"%d",&amp;n);//scan file for integer


    if (n &lt; score){
        if(highscore &lt; score ){
            if(end==true){
                fprintf (FPtr, "%d" , score);//print the score to file if it is higher than the score already there
                rewind(FPtr);//rewind the file, so pointer starts at begining
                fscanf(FPtr,"%d",&amp;highscore);//scan file for int
            }
        }
    }

    fclose(FPtr);//close pointer to file

}
</code></pre>

<p>fopen seems to overwrite what was in the file already and leaves it blank</p>
