HW9_1

(From: Exercise 3 on P.230) Declare a character array, and initialize it to "National Chi Nan University." Use a loop to change every character to uppercase. Then output the converted character array.
Hint: In the ASCII character set, values for uppercase characters are 32 less than their lowercase counterparts.
HW9_2

(From: Exercise 5 on P.230) Write a C++ program that will generate a random integer greater than 10,000. Output the integer and then output the digits in the integer in words. For example, if the integer was 345678, then the output should be:
```
The value is 345678
three four five six seven eight
```
Hint: The rand function returns a pseudorandom integer in the range 0 to RAND_MAX (32767). You may test the following example:
```
#include <stdlib.h>
#include <time.h>
// Print 5 random numbers.
srand( (unsigned) time(NULL) ); 
for (int i = 0; i < 5; i++ )
    cout << rand() << endl;
```
