Explanation: printf("%c %s", toupper(s1[0], &s1[1]));

toupper(s1[0]) will convert the s1[0] position data i.e., j to upper case i.e., J.

&s1[1] Will produce the address of the one index position of s1, but %s is there so it will convert it into string and then uppercase.

Suggestion: Use %u for unsigned integer for address

b) Answer: d) None of the above

Explanation: printf("%c %s", toupper(s2[1], &s2[0]));

toupper(s2[1]) will convert the s2[1] position data i.e., i to upper case i.e., I.

&s2[0] Will produce the address of the zero index position of s2, but %s is there so it will convert it into string and then uppercase.

Suggestion: use %u for unsigned integer for address
