Which of the following correctly declares a dynamic 2d array of size x * y on the heap? Justify why the others are incorrect. a) int** p = new int[x][y]; b) int** p = new int*[x]; for

Explanation / Answer

#include <iostream>
#include <conio.h>
using namespace std;

char* charArray(char* message, int length);

int main()
{
   // lenth of the char array
const int len = 10;
// declaring message
char message[len];

// calling charArray fucntion
cout << charArray(message, len) << endl;
   //getch();
return 0;
}

char* charArray(char* message, int length)
{
for(int i = 0; i < length; i++)
{
message[i] = 'a';
}
return message;
