Create an 6 x12 int M[6][12] whose elements represent rainfall for each month over 6 years. • Write a function Populate(int *M_ptr[], int row, int col) that populates the rainfall for each month using a pseudo random number generator (PRNG). The C++ programming language provides a random function that provides such capability.

Create an 6 x12 int M[6][12] whose elements represent rainfall for each month over 6 years. Write a function Populate(int *M_ptr[], int row, int col) that populates the rainfall for each month using a pseudo random number generator (PRNG). The C++ programming language provides a random function that provides such capability. • #include <cstdlib> srand(seed) - primes the random generator seed - unsigned int (Prime number - pick 37) unsigned in RV = rand() - returns a new random number(0-4Gig) RV = RV % 75 - normalizes the numbers to be less than 50 • Write a function YearAvrg(int *M_ptr[], int row, int col);that calculates the average rain per year over 12 months and prints the value • Write a function MonthAvrg(int *M_ptr[], int row, int col) that prints the average rain per month over 5 years. Find the total rainfall for year #3.
