Homework 5 (Due Oct. 16 in class)

Read: Section 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.15, 3.16, 3.17;
Pay special attention on 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.16;
Compile and run the 19 examples in Chapter 3.

Solve the following Problems:
Problem (3-27): (p. 231).
Problem (3-28): (p. 232);
Problem (3-34): (p. 232);

Hint: (you don't have to follow this hint if you can solve these problems)

Exercise 3.27:

(1) Write a simple program which input a fTemp

output a cTemp. Test your code, for example

if your fTemp=32, the output cTemp should be 0.

If you done, save as "version1".

(2) Use a for structure to do a 100 input/output.

for ( int i = 0; i <= 100; ++i )

If you done, save as "version2".

(3) Try to make the output looks like a table.

If you done this, save as "version3".

(4) Then do input fTemp output iTemp part.

If you done, save as "version4".

Break a problem into a few small simpler problems, and then do it one by one. If you try to do this problem

in one step, most likely, you will not be successful. For example, you may break this problem into 4 parts:

(1) input ONE Ctemp, output a Ftemp.

(2) input ONE Ftemp, output a Ctemp.

(3) Print the table the problem asked.

(4) Print a similar table only for even number inputs, i.e. Ctemp = 2, 4, 6,. . . 100.)

(5)One of the function suggested is as the following, you should write the second function.

int celcius( int fTemp )

{return static_cast< int > ( 5.0 / 9.0 * ( fTemp - 32 ) ); }

Exercise 3.28:
You should write and test the function first.

Exercise 3.34:
A line of the function suggested is as following:
return rand() % 2;
