1) Given the following code and program output:
10 int main() {
11    int x=5, y=3;
12    cout << sum(x) << "\n";
13   cout << sum(x, y); << "\n";
14    return 0;
15 }

Example Output
15
8

1) Code a function definition for the sum function in line 13 to return the summation of x.
2) Overload the function definition for the sum function in line 14 to return the sum of x and y.

10) Write an InsertFirst function for a partially filled array. 
This function should accept all required data as input parameters.

Example
If an array contains 7,10,3,9,5 and the InsertFirst function is called with a value of 20, the array will become 20,7,10,3,9,5.
