Different way of accessing array elements in C

Question

I am a teaching assistant for a C programming course, and I came across the following line of C code:

char str[] = \"My cat\'s name is Wiggles.\";
printf(\"%         


        

Answer 1

if str is an array of type char, then we can access any index say i as below-

1. str[i]
2. *(str + i)
3. char *p = str, then access the index i as p[i] or *(p+i)
