Array Allocator... Need a lil C++ help

[Jerochy]

Really can't quite figure out what is wrong here. The problem wants me to dynamically allocate an array of doubles, populate it, and return the point to a new array. Also, the function should take in an integer parameter that shows that indicates of the new array. 

Here's my code: 
 

 

 

#include <iostream>

#include <array>

#include <iomanip>

#include <string>

 

 

using namespace std;

 

int main()

{

int size = 1000;

int*number;

int getNumber();

int *prt = nullptr;

 

void getNumber(int*ptr);

{

cout << "Enter a number";

cin >> ptr;

 

}

 

for (int i = 0; i < size; i++)

{

intPtr = 0;

cin >> intPtr;

delete[]intPtr;

}

int*buildArray();

{

int*array = new int;

for (int i = 0; i < size; i++);

{

array = i;

return array;

}

}

 

 

 

}

Any help at all would help thank you!

i don't think I understood what you need? You want to create an array of doubles, populate it and return the pointer to that array?

 

If I understood correctly, this is what you want:

#include <iostream>using namespace std;double * buildArray(int S);double * buildArray2(double *, int, int);int main() {	int n;	double * arr;	do {		cout << "Input size of the array: ";		cin >> n;	} while (n < 0);	cout << "Building array..."<<endl;	arr = buildArray(n);	cout << "The created array : ";	for (int i = 0; i < n; i++)		cout << arr[i] << " ";	cout << endl;	//I think you also want to create an array starting from a pos the user enters?	int pos;	double * arr2;	do {		cout << "Input pos: ";		cin >> pos;	} while (pos < 0 || pos > n);	arr2 = buildArray2(arr, pos, n);	cout << "The second array: ";	for (int i = 0; i < n - pos; i++)		cout << arr2[i] << " ";	cout << endl;	system("pause");	return 0;}double * buildArray(int n) {	double * temp = new double[n];	for (int i = 0; i < n; i++)		temp[i] = i;	return temp;}double * buildArray2(double* arr, int pos, int n) {	double * temp = new double[n - pos];	int k = 0;	for (int i = pos; i < n; i++) {		temp[k] = arr[i];		k++;	}	return temp;}
