#include <stdio.h>
int main(void)
{
int n = 8;
printf("%d %p\\n", n, &n);
for (int n = 1; n < 3; n++) { printf("%d %p\\n", n, &n); }
printf("%d %p\\n", n, &n);
for (int n = 1; n < 3; n++)
{
printf("%d %p\\n", n, &n);
int n = 100;
printf("%d %p\\n", n, &n);
n++;
printf("%d %p\\n", n, &n);// n = 100 over , enter "for (int n = 1; n < 3; n++) " , n = 1 for this moment, after n++;
}
printf("%d %p\\n", n, &n);
return 0;
}
