  int main(void)
  {
    FILE *fp;
    float bal[5] = { 1.1F, 2.2F, 3.3F, 4.4F, 5.5F };
    int i;

    if((fp=fopen("test", "wb"))==NULL) {
      printf("Cannot open file.\n");
      exit(1);
    }

    if(fwrite(bal, sizeof(float), 5, fp) != 5){
      printf("File read error.");
    }
    fclose(fp);

    char str[80];
    float f;

    fscanf(fp, "%s%f", str, &f);
    fclose(fp);

  }
