Write C++ program to find the Sum of Array Elements using Pointers. Run the code on the following array and show your results (3, 77, x, 12, 8} where x is the 6 Exercise 2: Write C++ program to add two numbers using pointers. Run your code on x and y being entered by the keyboard where x and y are 5,6 Exercise 1: For the given matrix where x is the 6, 2 -4 H a. b. C. d. h || 3 4 2 6 0 -X 3 -2 -1 2 6 6 row 1 row 2 row 3 Find the transpose of the matrix (ht). (replace rows with columns and columns with rows). Loop over the whole matrix h and list the indexes that meet the following conditions: Even and -ve numbers. Find the averages of each row in the matrix (ht). Show results from a, b and c as screenshot with your code.
