You need to generate a (5x12) rain matrix (Rain[5][12]) that contains the average rainfall over 12 months for a 5 year period. You program should do the following steps: Create a 5x12 integer rainfall matrix Create a 5 element array of int pointers(int * Rain[5]) and assign each pointer to the address of the first element of each row Populate the elements of the matrix with pseudo-random numbers having a range from 0-100 Use the rand( ) function to generate your temperatures. The output of rand() should be mod with 100 (rand()%100) in order to get reasonable rainfall values. Init the random number generator with long seed = srand(67) This task should be performed by a function, void RainGen(int* Rain[ ], int R, int C), that populates all the matrix entries. After generating all rainfall matrix entries, print the entire matrix using the function, void Print(int* Rain[ ], int R, int C); Calculate the total monthly Rainfall per year for the entire five years. Use the following function, int Year(int * Rain[], int C); Print the total yearly sum Calculate the total monthly rainfall for the entire five years by using the following function, int Month(int *ptr, int R, int C); Where ptr = &Rain[0][0] Print the total

Question

You need to generate a (5x12) rain matrix (Rain[5][12]) that contains the average rainfall over 12 months for a 5 year period.  You program should do the following steps:

  • Create a 5x12 integer rainfall matrix
  • Create a 5 element array of int pointers(int * Rain[5]) and assign each pointer to the address of the first element of each row
  • Populate the elements of the matrix with pseudo-random numbers having a range from 0-100   Use the rand( ) function to generate your temperatures.  The output of rand() should be mod with 100 (rand()%100) in order to get reasonable rainfall values. 
    1. Init the random number generator with long seed = srand(67)
    2. This task should be performed by a function, void RainGen(int* Rain[ ], int R, int C), that populates all the matrix entries.
  • After generating all rainfall matrix entries, print the entire matrix using the function, void Print(int* Rain[ ], int R, int C);
  • Calculate the total monthly Rainfall  per year for the entire five years. Use the following function, int Year(int * Rain[], int C);
  • Print the  total yearly sum
  • Calculate the total  monthly rainfall for the entire five years  by using the following function, int Month(int *ptr, int R, int C);
    1. Where ptr = &Rain[0][0]
  • Print the total
