Write a C++ program to find the largest and smallest element of an array. You will need to input the array as an input. It shouldn't be any limitation on the number of array elements. Array items can be any number from negative to positive.

this is what i have so far and i cant figure what i am doing wrong...please help

//int num[10];

double largestNum = 0;

double smallestNum = 0;

int size;

cout << " enter number elements: " << endl;

cin >> size;

double number[size];

int index;

for (index = 0; index < size; index++)

cout << " enter the numbers: " << index << endl;

cin >> number[index];

//double largestNum = num[0];

//double smallestNum = num[0];

for (index = 1; index < size; index++)

if (num[largestNum] < num[index])

largestNum = index;

cout << "largest element is: " << num[largestNum] << endl;

//for (int index = 1; index < 10; index++)

if (num[smallestNum] > num[index])

smallestNum = index;

cout << "smallest element is: " << num[smallestNum] << endl;

}

system("pause");

return 0;

}
