In C++, Declare an array of integers and of size 10, fill the array with numbers without sorting it.

a. Write a function call it findNums, the function accepts any array of integers, the size of the array, and an integer call it sumofTwo. The function shall find any two numbers stored in the array such that the summation of the two numbers equals the third parameter sumofTwo. Hint: use nested loops.

b. Resolve part a without using nested loops. Hint: sort the array.
