Problem 1. Consider the following C code: \#define STRLEN 20 char mystring[STRLEN] = "I love CS!"; char cp= \&mystring [4]; Assume that the first byte of array mystring has address x. For each of the following expressions of type "pointer to char", tell (i) the value of the expression, i.e., the address it refers to, and (ii) the value contained in the byte at that address. If it is not possible to tell the value, write "unknown". Note: For full credit (2 points) both parts must be correct. As an example, for the expression cp, you would answer (i) x+4, and (ii) 'v'. a. cp+6 b. cp[19] c. cp9 d. cp[1]
