In C language, the life time and scope of a variable is defined by its storage class. The following are four types of storage class available in C language. auto register extern static In this article, we will discuss the ‘static’ storage class and explain how to use static variables an...
within the function defining the variable. After exiting the function, you cannot use it even though it still exists.(2) allow the static class of a construction class to assign initial values, such as an array, if the initial value is not given, the system automatically assigns 0 values.
phpclassPerson{staticfunctiontellAge(){static$age=0;$age++;echo "The age is:$age ";}}echo Person::tellAge();//output 'The age is: 1'echo Person::tellAge();//output 'The age is: 2'echo Person::tellAge();//output 'The age is: 3'echo Person::tellAge();//output 'The age ...
static Member (in Function) variable:函数调用完成后,变量保存状态,再次调用函数,不会重新分配空间 Member(in Funcition) variable:函数内的生命周期 static Member(in Class) variable:属于类范围, Member(in Class) variable:属于类派生的特定对象,生命周期和对象一致...
classTest{public: Test():a(0){}enum{size1=100,size2=200};private:constinta;//只能在构造函数初始化列表中初始化staticintb;//在类的实现文件中定义并初始化conststaticintc;//与 static const int c;相同。}; 定义和声明最好分别放在.h和.cpp中。
