关于c语言auto变量和static变量区别

请解释一下区别#include<studio.h>void AddOne(){     auto int ia=1     ia=ia+1     printf("%d\n",ia);}int main(){     print("the first number is:")     AddOne();     print("the second number is:")     AddOne();     return 0;}-----------------------------------------------------------#include<studio.h>void AddOne(){     static int ia=1     ia=ia+1     printf("%d\n",ia);}int main(){     print("the first number is:")     AddOne();     print("the second number is:")     AddOne();     return 0;}
