Q.No.3.                                                                                                                                                       You are given a matrix of 3 rows and 4 columns. (implemented as a two dimensional array of type integer “int x[3] [4]”), you are required to write main and functions in C++ to do the following: A main function which inputs integer values from user and stores them in the array, then calls two functions display_row_sum( ) and display_column_sum( ).   Function display_row_sum( ) gets the two dimensional array as argument and finds out the sum of each row and displays it separately.   Function display_column_sum( ) also gets the two dimensional array as argument and finds out the sum of each column and displays it separately.   So for the following array: 2    4    6    8 1    2    3    4 10  20  30  40   we might get: Sum of Row 1 = 20 Sum of Row 2 = 10 Sum of Row 3 = 100 Sum of Column 1 = 13  …… and so on
