The type description of static variables is static. Static variables are of course static storage, but the amount of static storage is not necessarily static variables. For example, although external variables are static storage, they are not

Variable scope Local scope, global scope, file scope Local Variables : Also called internal variables, declared within the function (including the main function), the scope begins at the declaration of the variable, ending at the end of the

All variables in C language have their own scopes. The types of declarative variables are different, and their scopes are also different. Variables in C language can be divided into local variables and global variables according to the scope.I.

The difference between a static variable and a global, local variableA static global variable is formed by the description of the global variable (external variable), preceded by static. Global variables themselves are static storage, and static
