void read(FILE *input, char array[10][61])

{
for (int i = 0; i < 10; i++)

}
}
void smallest(char array[10][61])
{
int s = 0;
for (int i = 1; i < 10; i++)
{
if (strlen(array[s]) > strlen(array[i]))
s = i;
}
printf("\nSmallest strnig: %s\n", array[s]);
}
void upper(char array[10][61])
{
for (int i = 0; i < 10; i++)
{
int n = strlen(array[i]);
for (int j = 0; j < n; j++)
{
array[i][j] = toupper(array[i][j]);
}
}
}
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);
// print
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]);
}
