Chapter 7, Problem 7.17E
( What Does This Code Do?) What does the following
- // Ex. 7.17: Ex07_17.cpp
- // What does this program do?
- #include <iostream>
- #include <array>
- Using namespace std:
- Const size_t arraySize {10}:
- Inst whatIsThis (const array
- Int main ( ) {
- Array
- Int result {whatIsThis (a, array Size) };
- Cout << “Result is “ << result << end ] ;
- }
- // What does this function do ?
- Int whatIsThis (const array <int, arraySize>& b, size_t size ) {
- If (size==1) { // base case
- Return b[0];
- }
- Else { // recursive step
- Return b[size-1] + whatIs This(b, size-1);
- }
- }

try {
} catch (NullPointerException e) {
System.out.println ("got null pointer");
}
try {
} catch (ArrayStoreException e) {
