*This is the problem regards on the C programming. Review what you have learned of Pointer and array. Consider the array and pointer created by the following lines of code: int* ptr; int arr[] = ptr = arr; {3,6,9,12,15,18,21,24,27}; After running this code, the memory stack can be represented by the following table. Address OxA00 OxA08 OxA10 OxA14 OxA18 OxA1C OXA20 OXA24 OXA28 OxA2C OXA30 Value OxA10 OxA10 3 6 9 12 15 18 21 24 27 Name ptr arr C treats stack arrays and pointers a little differently. This exercise is about the true pointer variable ptr, but it is convenient to initialize ptr with the array called arr. For each of the C code fragments below, determine if it is a valid expression. If it is, what is the data type of the result (e.g., int, int*, ...) and what is the value of the expression? (Remember, if the expression is a pointer, the value is an address.) If it is not, why not? Feel free to put any of these fragments into a small C program to test the result. Note that the memory locations in the table are arbitrary. If you try to run the code, you will get different memory locations.
