C Programming Language

static storage class or variables

               A variable is declared to be static by prefixing its normal declaration with the keyword static, as in
                static int a;
since the property of a variable may be stated in any order we could also use
                int static a;

              Static variables can be  declared within a function. These variables retain their values from the previous call. i.e., the value that they had before returning from the function.

This is illustrated in the following example.
