semicolon button

If a reserved character has a special meaning in a particular context (called "reserved Purpose"), and the character must be used for other purposes in the URI, the character must be a percent encoding. To encode a reserved character, you first need to represent the ASCII value of the character as a two 16-digit number, and then place the escape character ("%") before it, placing it in the corresponding position in the URI. (for non-ASCII characters, you need to convert to a UTF-8 byte order, an

Today, I wrote a 51 program. during compilation, Keil always prompts that a semicolon was lost, but I couldn't find out where the semicolon was lost. It took me one afternoon to solve the problem, share your experience here to prevent others from making the same mistake! The prompt message is: Lcd12864.h (20): Error c129: Missing '; 'before' flag' The u8 flag I defined in the lcd12864.c file is 0; Make this

Today, I encountered a problem when writing SQL statements to query ORACLE data.

In JavaScript, we rarely omit semicolons, and for unnecessary trouble and code, if we omit it, what happens? For more information, please listen to tell.Look at the code!Fragment One:1 var a2 = 3 Console.log (a); >>8Fragment Two:var ab= 8console.log (a); >>undefinedconsole.log (b); >>8console.log (AB); >>uncaught Referenceerror:ab is not definedWhat did you see?You are not wrong, you can understand, when we press ENTER is to add a space, such as the above fragment one: var a = 8, but it found th

In a Scala program, the semicolon at the end of the statement is usually optional. Willing to add, if there is only one statement in a line can not add.However, if a line contains multiple statements, the semicolon must be added.Rules inferred by semicolonsThe specific rules for splitting statements are simple and effective. That is, unless one of the cases is established, the end of the line is recognized

Inserted only before, after one or more lines, and at the end of program input That means you can only omit a semicolon in one line, a block of code, and the end of a program. Which means you can write the following code Copy Code code as follows: function Square (x) { var n = +x return n * N } But can not write the same as the following code, so that the error-OH Copy Code code as follows: function Area

JavaScript syntax is similar to the Java language, with each statement ending with a ; statement block {...} . However, JavaScript does not enforce the requirement to add at the end of each statement ; , and the engine responsible for executing JavaScript code in the browser automatically complements the end of each statement ; .Note : Having the JavaScript engine automatically add semicolons in some cases alters the semantics of the program, resulting in inconsistent running results and expecta

Today, for example, write a simple pl/sql statement that looks at the newly-written statement in the buffer, as follows: Sql> L1 DECLARE2 I number (4): =13 BEGIN4 LOOP5 INSERT into EMP2 (empno) VALUES (i);6 EXIT when 1>2;7 i:=i+1;8 End LOOP;9* end; Find the second line to forget the semicolon '; ' When this is added, it does not add: 2 I number (4): = 1; Solution: In this case, you should add 2 semicolons, for example: 2 I number (4): = 1;; Look again

1. In the function body, that is, the content in the braces {}, the function call declaration and the function declaration that requires extra points at the end of the definition of the independent variable: for example, int max (a, B, c) define independent variables: for example, float x and y; 2. Add a plus sign at the end of a sentence (a semicolon is used for the statement used to complete the end), for example, the input and output functions: pri

Looking at a code like this, Scala treats it as two statements, X and +y, and if you want to use it as a statement, you can put them in parentheses (x+y)X+yOr you can put the + at the end of the line, and because of this, the string is similar to the + such infix operator, Scala's usual style is the bar operator at the end of the line instead of the wardrobe.X +YThe rule of the semicolon inference is simple, that is, unless one of the following condit

There are two ways of declaring a function:1, function //declarative definition functions2, var demo=function () {} //Function assignment expression definition function　　We usually call the function demo () like this.But if we add () to the end of a defined function, the parser is incomprehensible.If you wrap the function body part () to run and the parser does not error: ( function () {}) () // call anonymous function But in front of a Boolean operator (only one more excla

Yesterday because of a page CSS style increase, need to add the original CSS inside the style. Because of the addition of some changes in the head, so, the top of the style sheet modified a bit! The top of the original is: @charset "Utf-8"; Later, after I added something, and put this: @charset "Utf-8"; Put it on the top. But accidentally removed the semicolon, and became like this: @charset "Utf-8" The resulting page has styles that are not
