C++ program: Write a function that accepts an array/vector as an input and calculate the sum of all the elements in the array.  This function must use recursion to achieve this.  Show code: Please show all steps.

In C++, When an array is passed to a function as a pointer, the function doesn't know the size of the array. List 3 ways to handle this problem.

C++ Problem #1:   Create a blank 10x10 integer array using constants for the row and column Create a function printArray() that will print every row and column of the array Create a function notFound() that searches each element in the array and returns true if the passed number already exists in the array and false if it does not Create a function fillArray() that will fill the 2 dimensional array with unique random numbers from 0 to 100 inclusive.  No cells should have the same number.  Use the notFound() function in this function. Print the entire array. Request a column number to print and use a sentinal loop to make sure the row number is valid. If not then request a column number again Create a function printIter() that prints only the passed column using iteration Create a function printRecur() that prints only the passed column using recursion Print the requested column using printIter() and printRecur()   Sample output:   The array is:   Row 0: 41, 85, 72, 38, 80, 69, 65,…

What does "base address of an array" mean, and how does it come into play in a function call?
