Static function (modifier function, local variable, global variable)In the C language, the literal meaning of static can easily lead us astray. In fact, it has three functions.(1) first introduce the first and most important one: hiding.When we

concept: static variables are scoped to a file , the program starts with space allocated, the space is freed at the end, the default is initialized to 0, and its value can be changed when used. static variables or static functions only the code in

Static variables exist only in the scope of the function, static variables only live in the stack, the next time you call this function, the value of the variable will be preserved Static variables exist only within the scope of the function, and

1. Constants: Also known as final variables, can only be assigned once in the entire programfinal int num = 1215;num = 1216; //error, can only be assigned once2. Class member variable: A variable that is not defined in a method is a member variable,
