Write C statements to do the following: 1. Declare integer pointer variables named int ptri and int ptr2. 2. Allocate an anonymous integer variable, and make int ptr1 point to it 3. Input an integer value from the keyboard and stores it in the anonymous variable of question 2 4. Display the value of the anonymous variable of question 2. 5. Cause int ptr2 to point to the anonymous variable of question 2. 6. Declare a double pointer variable named double ptr 7. Ask the user to enter n, the number of values to be processed; then allocate an anonymous array of n double values, and make double ptr point to it. Fill the anonymous array of question 7 with n input values, entered from the keyboard. 9, Deallocate the storage of the anonymous variable of question 2 and the anonymous array of question 7
