static variable is a variable which declared inside class
using keyword static.
its value used only in that class not overall program


example:


#include <stdio.h>

void func() {
static int x = 0; // x is initialized only once
across three calls of func()
printf("%d\n", x); // outputs the value of x
x = x + 1;
}

int main(int argc, char * const argv[]) {
func(); // prints 0
func(); // prints 1
func(); // prints 2
return 0;
}
