  • Static variable have a property of preserving their value even after they are out of their scope.
  • Static variable preserve their previous values in their previous scope and are not initialized again the new scope.

    • Syntax

    static data_type var_name = var_value;
    • Here data_type –> Data types like int, char, float etc.
    • Var_name -> Name of the variable given by user.
    • Value -> Any value to initialize. By default, it is zero.

    • A static variable remains in the memory while the program is running.
    • Static variables are allocated memory in data segment, not in stack segment.
    • Default values of static variables is assigned as 0 if not initialized explicitly.
    • In C, static variables can be initialized using constant literals.
    • Static global variables and functions are possible in C. The purpose of these is to limit scope of a variable or function to file.
    • Static variables cannot be declared inside the structure. The reason is compiler requires the entire structure elements to be placed together.
    • Memory allocation for structure members should be contiguous.
