Code in C#

1. Write the code for each of the following: a) Use an appropriate pointer to dynamically allocate memory for one integer value. b) Use an appropriate pointer to dynamically allocate memory for two double values. c) Use an appropriate pointer to dynamically allocate memory for 5 integers, initialize them to some values and print them. Can't use []. d) Use an appropriate pointer to dynamically allocate memory for 20 characters, initialize them to something and print them. Can't use []. e) Use an appropriate (double) pointer to dynamically allocate memory for 25 characters for 2D array, initialize them to some values and print them in 2D array format (like a matrix or table). Can't use []. f) Repeat part (e) with single pointer (Hint: 2D array is really a 10 array)
