将静态变量作为参数传递给函数

Question

Is there any problem with passing a static variable to a function as a parameter? The program printed 1 0. So, are static variables also passed by value as usual?

#include<stdio.h>
int main()
{
    static main;
    int x;
    x=call(main);
    printf("%d %d",x,main);
}
int call(int address)
{
    address++;
    return address;
}

Answer 1

Yes, static variables are passed just like any other variable.

But I would expect you to have some compile errors when you name your variable with the same name as the function.

Answer 2

There's no difference in variable passing with statics.

Note you need to include the type in your code: static int main;

And I wouldn't name a variable as main because that might be a reserved keyword.
