And here's the C version. Note the heroic attempt to check for errors, and yet 
how most errors are not checked for:
------------------------------------------
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    FILE *file;
    char buf[128];

    file = fopen("fileio.txt", "w");
    if (!file)
    {
       fprintf(stderr, "Couldn't open file.\n");
       exit(1);
    }

    fprintf(file, "hello");
    fclose(file);

    file = fopen("fileio.txt", "a");
    if (!file)
    {
       fprintf(stderr, "Couldn't open file.\n");
       exit(1);
    }

    fprintf(file, "\nworld");
    fclose(file);

    file = fopen("fileio.txt", "r");
    if (!file)
    {
       fprintf(stderr, "Couldn't open file.\n");
       exit(1);
    }

    fgets(buf, sizeof(buf), file);
    fgets(buf, sizeof(buf), file);

    fclose(file);

    puts(buf);

    return 0;
}
