Question

i am trying to print a line from a text file then go to the next line and print that until there is no more lines left to print. This is what i have so far, but it only works the first time that i run the program.

void ReadFile(FILE *a)
{
    char line[23];
    while(fgets(line, 22, a) != NULL)
    {
        printf("%s", line);
    }
}

Answer 1

You will need to reset the file pointer back to the start if you want to do this multiple times with the same FILE object:

void ReadFile(FILE *a)
{
    char line[23];
    rewind(a);
    while(fgets(line, 22, a) != NULL)
    {
        printf("%s\n", line);    // Added new line
    }
}
