9. Programming style
· More regular programming style
W plus a space in every side of a binary operator
W In every comma instead of adding a space
W, add a space after each keyword
w one line of statement
Do not have spaces before the W semicolon
W function's garden brackets and parameters do not add spaces
W does not add space between one dollar operator and operand
Add a space with each side of a binary operator:
Console.writeLine ("{0}", result / 13); // Recommended
Console.writeLine ("{0}", result / 13); // Not recommended
In every comma instead of adding a space:
Console.writeLine ("{0}", result / 13); // Recommended
Console.writeLine ("{0}", result / 13); // Not recommended
Each keyword is added to a space:
IF (OneELINE (Comment) ... // Recommended
IF (OneELINE (Comment) ... // Not recommended
Don't have spaces before the semicolon:
Console.writeLine ("{0}", result / 13); // Recommended
Console.writeLine ("{0}", result / 13); // Not recommended
The garden bracket and parameters of the function are not spaced:
IF (OneELINE (Comment) ... // Recommended
IF (OneELINE (Comment) ... // Not recommended
No spaces between one dollar operator and operand:
keywordcount; // recommended
keywordcount; // is not recommended
10. Find the wrong
Bool checked;
... 1
Public static void main ()
{ ... } 2
INT matched = symbol.match (input)
IF (Match> 0)
{
....
} 3
CHAR OPTIONAL = "?"
String theory = 'complex'; 4
INT matched = 0_OR_MORE (Symbol);
... 5
The error of paragraph 1: Checked is a keyword
The error in paragraph 2: Not main, but main
Paragraph 3: Variable declaration statement has no semicolon
The error of paragraph 4: The character value must be represented by single quotes, and the string must use dual quotation to indicate the error error: the first error is that the identifier cannot be started with the number; the second error cannot be used underline Identifier.
