Question

9. At your job, you are creating a library. A co-worker brought this test code to you. They expect that the output would be "12 12 12 12 12". However, they are getting "Empty List" (a) Describe why the error is occurring. (b) Explain how to fix the code. #include <iostream> using namespace std; CON void increaseArray (int* array, int size, int value) { int newSize = size + 5; if (size ==0) { size = 5; O int* newArray = new int [newSize]; for (int i=0; i<size; ++i) { newArray [i] = array[i]; for (int j-size; j<newSize; ++i) { newArray [j] = value; delete [] array; size = newSize; array = new Array; newArray = nullptr; void printArray (int* array, int size) { if (size ==0 || array == nullptr) { cout << "Empty List" << endl; else { for (int i=0; i<size; ++i) { cout << array[i] << ""; cout << endl; int main() { // test program int* testArray = nullptr; int testSize = 0; int test Value = 12; increase Array (testArray, testSize, test Value); printArray (test Array, testSize);

Answer 1

(a) Reason for Error


(1) testSize is not updated as the variable is passed by VALUE
(2) Second for loop inside increaseArray should run from j = 0 to newSize

(b) Fix


(1) increaseArray function, void increaseArray(int *array, int &size , int value)
(2) Second for loop should run from, for( j =0 ; j<newSize ; ++j )

PLEASE COMMENT if there is any concern.
