Static Variable Fetching Techique

See more:

C++

To withdraw a normal member variable's value from a structure/class the complier reaches the variable by getting the offset of the element from the beginning address of the structure/class and then adding the base address to the offset.

How is a static variable fetched by the compiler?

Sample code:
In both the structures shown below how will the compiler fetch the variables?

struct cde
{
    char c;
    int d;
};

struct xyz
{
    static char x;
    int y;
    static int z;
};

char xyz::x = 'Y';
int xyz::z = 47;

main()
{
 cde C;
 xyz X;

 C.c = 'D';
 C.d = 4;

 X.y = 7;

 printf("%c %d\n",C.c, C.d);
 printf("%c %d %f\n",X.x, X.y, X.z);
}
