C Learner November 21, 2024 10:47 am PST imagine static global variables that declared and defined in header. In this case it's completely pointless that this global variable became internal linkage because wherever I include this header, I will always be able to access this static global ...

A static local variable exists only inside a function where it is declared (similar to a local variable) but its lifetime starts when the function is called and ends only when the program ends. The main difference between local variable and static variable is that, the value of static variab...
variable b=100 int(20) int(30) 如果在函数内部嵌套定义了另外一个函数,要想使用并改变父类函数中变量中的值,可以使用引用传递的方式(可以理解成C++中的引用); 2.static和c语言中的static使用方式是一样的,函数中使用它之后,当函数执行完毕之后,该变量的空间不会被立即回收,而且只被初始化一次: 1functionrun...
