i want to assign what is read from a text file to an int. In the text file there will only be 1 number such as 1000 or 3023. I want to do this to have a High Score system in my black jack game, any ideas?
here is the code i am using to read from a file
fp=fopen("high scores","r");
if ( fp != NULL )
{
while ( (highscore = fgetc( fp )) != EOF )
putchar( highscore );
test=highscore;
fclose( fp );
}
i would like to assign the number that is read to an int.
-thanks
the problem with reading from files is that it stores it as a char or string
not an int`
Asking the right question is sometimes more important than knowing the answer.

fgetc() only gets one character from a file, so really doesn't do what you want directly. The easiest way would be to would fgets() to read the data into a string, the use atoi() or atol() to convert it to a number.
Here's some sample code that might help you
Code:if (fgets(buffer, sizeof buffer, fp) != NULL) printf("%d\n", atoi(buffer)); else printf("Error: Number not found\n");
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
if i use the code above, how would i right to a file?
fprintf(fp, "%d", i);
I presume you are talking about storing your highest score?
