Chapter 2.5, Problem 9E

(Practice) a. Using Figure 2.14 and assuming the variable name rate is assigned to the byte at memory address 159, determine the addresses corresponding to each variable declared in the following statements. Also, fill in the correct number of bytes with the initialization data included in the declaration statements. (Use letters for the characters, not the computer codes that would actually be stored.)

$\begin{array}{l}floatrate;\hfill \\ charch1=\text{'}M\text{'},ch2=\text{'}E\text{'},ch3=\text{'}L\text{'},ch4=\text{'}T\text{'};\hfill \\ doubletaxes;\hfill \\ intnum,count=0;\hfill \end{array}$

b. Repeat Exercise 9a, but substitute the actual byte patterns that a computer using the ASCII code would use to store characters in the variables ch1, ch2, ch3, and ch4. (Hint: Use Appendix B.)
