The 'static' keyword ensures a variable retains it's value until
changed or the program ends. example below:
This function will always return 1 because every time the function is
called, memory is set aside for the variable 'a' and then it is set to
0. 'a' is dynamic.
int count(void)
{
unsigned int a = 0;
a++;
return a;
}
This function will return how many times the function was called until
the variable 'a' overflows back to 0. The 'static' keyword makes sure
memory is allocated for 'a' when the program begins and deallocated
when the program ends.
int count(void)
{
static unsigned int a = 0;
a++;
return a;
}
Cheers...
