width is less than the size of the type sizeof, the subsequent field will be stored next to the previous field until the position cannot be accommodated.2) If the adjacent bit field field is of the same type, but its bit width is greater than the size of sizeof of type, then the subsequent field will start from the new storage unit, with an offset of an integer multiple of its type size.3) If the adjacent bit domain field type is different, the speci
Attention:1 structure within a struct once again defines a struct but does not create an instance of the struct bodyIn other words, the variables inside the struct that are defined again are treated as member variables of the parent structure.1 structTianchao2 {3 intdata;4 Charname[ -];5 structBeijing//a struct is defined within the structure again but no instances of the struct are created6
In the previous section, the flowchart we drew, remember? Judging the part we will, the difference cycle, below I will introduce three kinds of commonly used loops.Loop structure while loop (when looping, at least my C language teacher calls it)Let's introduce the syntax, as follows while (conditional expression) { // Here is the loop body, when the above condition expression is true, the loop body is ex

1.if statements2.do-while statement: post-test Loop statement, The code of the loop body executes at least once.3.while statement: pre-test Loop Statement.4.for statement: pre-test Loop Statement. Note: There is no block-level scope in ecmascript, so variables defined inside the loop can also be accessed externally.eg1 var count=10; 2 for (var i=0;i) {3
To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as foll
static HTML page, and when the cache property of the Smarty is set to True, The user's Web request is converted directly to this static HTML file during the Cachetime period set by Smarty, which is equivalent to calling a static HTML file.4. Plug-in technology: Smarty can customize the plugin. Plugins are actually some of the custom functions.5. If/elseif/else/endif can be used in the template. The template file can be easily reformatted by using a j

Auto enables the compiler to automatically parse the type that an expression belongs to
Auto generally ignores the top-level const, preserves the underlying const, and if you want the inferred auto type to be a top-level const, you need to explicitly specify the const auto

Function Declaration
Function declaration (FD) is a function:
There is a specific name
Position in the source code: either in the Program level or in the FunctionBody of other functions
Create in the context stage
Variable objects
The following statement
function exampleFunc() { ...}
The main feature of this function type is that they only affect variable objects (that is, the function is stored in the context VO ). This featur
The concept of recursion : The function body calls the function itself until a condition is met and no longer continues to be called.conditions to be met : (1) There is a process of repeated execution (call itself);(2) There are conditions for jumping out of the iterative process (function exit);Note : (1) There must be a loop-end condition in the recursion.(2) Each invocation of a recursive function needs to be stored with a stack, which is prone to
Use CSS style 3
The third is based on the relevant CSS style principles. The selector and cascade are so good that we know the early versions from CSS. It adds new features, including new selectors, pseudo classes, and attribute loads. Using these features makes it easier to create new functional la S. Let's dive in.
