}
}
}
int main()
{
char filename[30];
// array of 10 strings
char array[10][61];
printf("Enter filename: ");
gets(filename);
// open file
FILE *input = fopen(filename, "r");
// read into array
read(input, array);
// close file
fclose(input);
// remove newline
remove_newline(array);
printf("Contents of file:\n");
for (int i = 0; i < 10; i++)
printf("%s\n", array[i]);
// print smallest string
smallest(array);
// uppercase
upper(array);
// print again
printf("\nContents of file after converting to uppercase:\n");
for (int i = 0; i < 10; i++)
printf("%s\n", array[i]);
