C for Dummies 2nd Edition Errata

COLOR is a Win2000 command. As such, that command runs before your COLOR.EXE program does. To solve this, run your COLOR program from the command prompt in this manner:

.\color

Just as in Unix, if you specify the program file's location, it runs from that location. In this case, .\ specifies the current directly, so that your COLOR command runs instead of the Windows COLOR command.

In the first paragraph, /* is used instad of */. The sentence should read, "Remember that final */; otherwise, the C compiler thinks that your whole program is just one big, long comment (possible, but not recommended)."

The last word in the first paragraph on the page should be number not letter. Try not to use a number as the first letter of a variable name.

More formatting woe. The range for a singed long int is from -2,147,483,648 to 2,149,483,647; the range for an unsigned long int is from 0 to 4,294,967,295.

The last example on the page is wrong. I was drunk.

The wildcard %6f spits out six digits to the right of the decimal place whether the value has a decimal part or not. So the float value 123456 would print like this:

123456.000000

The value 1234.5678 would print like this:

1234.567749

(Those are imprecise values to the right of the decimal, but there are six of them.)

To just print out six digits to the left of the decimal, use %6.f. To print out six digits to the right, use %.6f.

In the sidebar, a reference is made to looking up a value in Appendix B. Sadly, Appendix B does not list the character referenced.

Page 126

Third paragraph, var would be an integer variable, not a char.

In the source code, the variable key should be defined as an int, not a char.

The sleep() function requires the header file unistd.h.

Page 262

Second to last paragraph, it should be the atoi() function, not atio().

Page 302

The defined variable BLECH is specified in the code, though it should be written BELCH. (Actually, the header file is incorrect, but the error shows up in the code. I use BLECH as a work and the proofer probably changed it to BELCH.)

Page 309

In the 8th paragraph, the \t character moves the cursor a predefined number of spaces to the right, not to the left.

Pages 314-316

Typesetting errors make the math on this page read goofy. Starting with the third from last paragraph on page 314:

4 × 4 is 4², not 42

4 × 4 × 4 is 4³, not 43

In the first paragraph atop page 315, the value is 4⁵ not 45. And in the fifth paragraph, it should read 4² not 42.

In the last paragraph on page 315, the value should be 2⁸, not 28.

On page 316, the first paragraph about the check marks, the value 28 should be 2⁸.

Finally, the last bullet on page 316 should show 2⁸ as the value for 2^8.

Page 334

The code sample at the top of the page should read:

m = big % 5;

Page 366

The directory name for Dev-C++ is listed incorrectly. It should be C:\Dev-C++ not C:\Dev=C++.
