Question

Question 16 (4 points) Write a complete C program that declares four variables of type integer (i.e integer variables) and four variables of type pointer to integer (i.e. integer pointers). Assign the addresses into the pointers. Using the indirection operator with a pointer, assign the values 1, 2, 3, and 4 into the four integers. (Use the indirection operator with the pointers to write the integer values.) Your program should write the addresses and values of all eight variables to the screen. Use a tabular layout to list the variable's name, type, value, and addressee. Notice that the addresses of the integer variables are the values of the pointer variables. Sample run: VARIABLES TYPE VALUE ADDRESSES int int* x7fff32b65c08ex7fff32b65c18 int int* 0x7fff32b65c0c int int 0x7fff32b65c10 0x7fff32b65c18 int int 0x7fff32b65c140x7fff32b65c18 0x7fff32b65c08 a ptr 0x7fff32b65c0c 2 0x7fff32b65c18 b ptr 0x7fff32b65c19 c_ptr 0x7fff 32b65c14 4 d_ptr
