    char tempStr[128];
    FILE *fPtr = fopen("NEW.TXT", "r");

    while(!feof(fPtr)) {
    fgets(tempStr, 80, fPtr);
    fprintf(stderr,"%s\n", tempStr);
    }

    your code doesnt work properly

    Hi,

    I tried your code and i cannot get it to read the whole txt file.
    Your code only reads the first line?
    Can you help?

    thanks

    Are you just trying to dump the entire contents to the screen?
    Code:
    FILE *fp = fopen( "myfile.txt", "r" );
    int c;
    while ( (c=fgetc(fp)) != EOF ) printf("%c", c );
    You really should read up on the f* functions and learn a bit more on how they work.

    Additionally, you may want to use psesudo code to explain your problem first:
    Code:
    while we're not at the end of the file
        read a line
        put the line on the screen
    As per above, if you used a loop with the previous poster's code, you'd have your answer already.

    Hope is the first step on the road to disappointment.
