What does static variable mean?
there are 3 main uses for the static.
1. If you declare within a function:
It retains the value between function calls
2.If it is declared for a function name:
By default function is extern..so it will be visible from other files
if the function declaration is as static..it is invisible for the outer files
3. Static for global variables:
By default we can use the global variables from outside files
If it is static global..that variable is limitied to with in the file
