C Programming - Strings

Will the program compile successfully?

#include<stdio.h>

int main()
{
    char a[] = "India";
    char *p = "BIX";
    a = "BIX";
    p = "India";
    printf("%s %s\n", a, p);
    return 0;
}

For the following statements will arr[3] and ptr[3] fetch the same character?
char arr[] = "IndiaBIX";
char *ptr = "IndiaBIX";

Is there any difference between the two statements?
char *ch = "IndiaBIX";
char ch[] = "IndiaBIX";
