Coding Style

The Coding Rangers had their first somewhat informal meeting on Jan. 21 to determine a uniform coding style. They came up with the following:

• Comment as much as you can using /* ... */.
• At the top of every file, include your name, the filename, and the purpose of the file.
• Comment on what a function is supposed to do before the function definition.
• Change to newline once you reach column 80. Nothing to be typed beyond column 80!
• When naming variables,
  • use single letters (like i, j, a, or v) for counters only;
  • assign the variable a name that best describes what it is used for (but please don't make it too long);
  • and separate words with caps.
    Eg. noOfOrders, not nooforders
• When naming a function, name it according to what it is supposed to do.
  Eg. void updateDelivery, int setInitialValue, not void Deliveries, int InitialValues
• Class names must begin with a capital letter
• Declare each variable at the beginning of blocks.

Eg.

main () { int length = 0; // correct, at the beginning of the block ... ... int flag = 1; // incorrect, at the middle of the block if ( length = 0) { int i = 0; // correct, at the beginning of the block ... ... bool valid = true; // incorrect, at the middle of the block } return 0; }

• Declare each variable in a line by itself. It is easier to comment a variable this way. Do not use commas to separate the variable names if they have the same data type.

Eg. correct int i; //To count the number of times in for-loop int j;

int k; //To count another variable

Eg. wrong int i,j,k; //How do I separately comment

int i; int j; int k; //the variables here?

• Type four (4) spaces over for every block of code. (This is as opposed to tabbing.) For example:

main () {

int x; //Notice the four spaces over
int y;

for (x = 0, y = 10; x < 10 && y >0; x++, y++) {


printf("x is %d, y is %d\n", x, y);
printf("The sum of x and y is %d\n", x + y);
if (x == 5)
printf("We've reached the halfway point!\n"); //Moved four spaces over again }

printf("Hello, world!\n");
}


• Only main () will start at column 1. Tab every block of code four spaces over.
• Include an empty line after the declaration of variables (see above example).
• When using operators, make sure to have a space between the operands and the operator for readability.
  Eg. i = 0;, not i=0;
• For keywords such as while, for, if, else, put a space after the keyword and the expression following it.
  Eg. if (x == 0) is correct; if(x == 0) is incorrect
• When using brackets, put the opening bracket on the same line as the function or expression that opens it.
  Eg. CORRECT:
  int setSafeEmptyState {
...
}
  INCORRECT:
  int setSafeEmptyState
{
...
}
  

Issues

Each member will post updates about their progress on the project. Triumphs, conflicts, and blood and tears will go here.

Sunny

However, a new "Error E2040 C:\Borland\BCC55\Include\conio.h 1: Declaration terminated incorrectly" has appeared. Fixed! Feb11th
I am running into this error "Error E2209 biof.c 32: Unable to open include file 'conio.h'". Know a way to fix this? Fixed!

Donna

Feb 20, 2010 - Just found out yesterday that another variable, int ReadOnly, has been added to parameters passed to bio_edit. ReadOnly is supposed to toggle between ReadOnly and !ReadOnly. This changes the default of the switch statement slightly.

Feb 4, 2010 - Committed my bio_rows to trunk. I ran into a few troubles while compiling, the biggest being Borland. Never used this compiler before. The frustrating part, after fixing all of my mistakes, is forgetting to take note of what went wrong so that I know how to fix it in the future. However, as far as I can recall, some of the biggest problems were:

• Having to include -IC:\Borland\BCC55\Include \LC:\Borland\BCC55\Lib during compilation.
• Empty parameters in the function prototypes (in biof.h) actually needed the word "void" rather than just leaving them empty. (I just checked the function prototypes in the biof.c file, and some of them are empty. However, fixing just the .h file was enough). For some reason, they're as good as being not prototyped.

There was something hinky about visual c++, too, but I forget now. I'll keep it in mind for next time.
As for the actual coding, I forgot that the word "struct" has to be included when creating a struct. (struct text_info x;).

Shengwei

Just to reserve a space. :)

Dachuan

Placing void in Function(void) for Borland is important. It has gotten me frustrated a few times.
bio_putint() doesn't seem to work under VCC now? fixed

bio_move() doesn't not work in Borland. fixed

When using Putty, don't forget to set Function/Keyboard/Xterm R6!

When compiling on Mac: cc biomain.c biof.c -lcurses (and then) ./a.out

Cong

i really appreciate Sunny's help, my code works now.And i understand what link problem is.

Cgcheung

Not really an issue but my own mistake. A reminder to include "-l ncurses" to the compile line in linux >_> .

Helper Functions

void bio_putint(int val)

• It prints an integer on the screen.
  

char* toUpperCase(char* str)

• This function only changes those letters in lower case to upper case. It changes the original string.
  

char* myItoa(int val, char* str, int base)

• This function converts a decimal base integer to any other non-decimal base number, such as binary number or octal number, or hex number, and than converts that number into a string variable. Or, it converts a decimal base integer directly into a string. The function returns the address of the string at the end.
  

char* myFtoa(double val, char* str)

• This function converts a double to a string variable, and returns the string. There will only be 2 decimal positions shown in the string. If we want to print a double value on the console screen, we can say: bio_putstr(myFtoa(val, str)). I think there is no need to code another function for bio_putdouble.
  

int myPrint(const char* msg, ...)

• This function works very similar with printf in stdio.h library. Float data type dose not work here; only double dose. The function only shows 2 decimal positions.
  

Microsoft SkyDrive

We can put some useful files here.

• It's 25GB space, and the max size of a file which can be uploaded is 50MB.
• All files can be set a certain permissions to allow different kinds of access.
