A local variable is identified with one @, and a global variable is identified with two @ (common global variables are usually defined). declare the local variable Syntax: declare @ variable name data type. For example: declare @ numint; value assignment: There are two methods (@ num is the variable name, value is the value) set @ numvalue; nbsp; or nbsp; selec

1. What is a local variableA local variable is a variable that has a local effect and is defined inside a function. The scope is only within the function, the variables outside the function is not affected, that is, the same name function, if not in the function to do the global DeclarationThen there's no effect on the outside of the function.1x ="Alex"2 3 deffunc (x):4 Print('the value of x is', X)5x =

Typically, if there are two variables with the same name, one is a global variable and the other is a local variable, then the local variable has a higher priority within its scope and it masks the global variable.Scope operator Copy Code code as follows: #include using namespace Std; int num=10; int main () {int num; num=25; coutreturn 0

Global variables and local variablesVariables defined inside a function have a local scope, which defines the owning global scope outside of the function .Local variables can only be accessed within their declared functions, while global

that it is a function block, and for, while, if block is not a scoping criterion, you can look at the following examples: Second, JavaScript in the implementation of the entire script file in the declaration part of the complete analysis (including local variables), so as to determine the scope of real variables. How do you understand it? Look at one of the following examples: T

!--? php $a = 1; include ' b.inc '; ? copy code Here the variable $a will take effect in the include file B.inc. In a user-defined function, a local function scope is introduced. 　　 Any variables used inside the function will be limited to the local function by default, and this is a local variable. A PHP global variable must be declared
