If initialization is a part of declaration of a structure, then the storage class can be static.
Storage class in C decides the part of storage to allocate memory for a variable; it also determines the scope of a variable. All variables defined in a C program get some physical location in memory where variable's value is stored. Memory and CPU registers are types of memory locations where a variable's value can be stored.
Static' variables are by default initialized with value 0.
