Please finish the code in C++:

Open your exercise file and complete the TODOs in the C++ program which does the following: 1. It will read from a text file. Each line of the file contains a number. Provide the file name as a command line argument. Number of lines in the file is not known. 2. Create an array dynamically of a capacity (say 10) and store each number as you read from the file. 3. If you exhaust the array but yet to reach end of file dynamically resize/double the array and keep on adding.

#include #include

using namespace std;

//Uncomment the lines and implement the TODOs in the resizing logic void resize(int **arrayPtr, int *capacity) { // TODO increase the capacity by two times int newCapacity = cout<<"Resizing from "<<*capacity<<" to "<

// TODO dynamically allocate an array of size newCapacity int *newArray =

// TODO copy all data from oldArray to newArray

// TODO free the memory associated with oldArray

*arrayPtr = newArray; *capacity = newCapacity;

}

int main(int argc, char* argv[]) { if(argc != 2) { return -1; } string filename = argv[1]; ifstream data; data.open(filename.c_str());

int capacity = 10; int *arrayPtr;

// TODO Dynamically allocate space here for the array arrayPtr = int numOfElement = 0; string temp;

if(data.is_open()) { while(getline(data, temp)) { int toBeInsert = stoi(temp); if(numOfElement == capacity) { // Complete this function resize(&arrayPtr, &capacity); } arrayPtr[numOfElement] = toBeInsert; numOfElement++; } data.close(); }

for(int i = 0; i < numOfElement; i++) { cout << "Num: " << arrayPtr[i] << endl; } return 0; }
