What is the scope of static variables in programming?

What is the scope of static variables in programming?

Static variables have a scope limited to the block in which they are defined, but they retain their value between function calls.

Can you give me an example of a static variable in C?

Sure! In C, if you declare a variable as static inside a function, it will keep its value even after the function exits. For example:

void function() {
    static int count = 0;
    count++;
    printf("Count: %d\n", count);
}

What happens if I declare a static variable outside of a function?

If declared outside a function, a static variable has file scope, meaning it can only be accessed within that file.

Are there any differences in scope for static variables in C++?

Yes, in C++, static variables inside a class are shared among all instances of the class, while static variables in functions behave like in C.
