Char str[]="%d%s",arr[]="GatesQuiz";

printf(str,0[arr],2[arr+3]);

}

a)GQ

b)71 81

c)71 Q

d) compile time error

Answer 1

answer is C.

The printf statement will be printf("%d%s",0[arr],2[arr+3]);

0[arr] means *(arr+0) and here it is expecting number bcz of %d so answer is 71 (since ASCII value of A is 65)

2[arr+3] means *(arr+5) and here it is expecting character so Q printed.

Try %c instead of %s

yes, we cannot use "%s" and pass a character to printf. In that case it treats the character value as an address and tries to read a sequence of characters from that "assumed address" till it finds a '\0'; So, in most cases this should result in invalid memory access- segmentation fault.
