Answer / viswanath
Ans: 15.
Exp: a[++i] means i = 1; so 10 + 2 +3

Answer / nandkishor
Ans: 19.
Explanation: First expression (++i) execute. Hence i=1;
Than a[++i]=a[2]=15.
And than ++i=3.
Hence evaluation will be 15+3+1=19.
Note that expression closed in braces have high precedence.

1) int i=5; j=i++ + i++ + i++; printf("%d",j);This code gives the answer 15.But if we replace the value of the j then anser is different?why? 2)int i=5; printf("%d",i++ + i++ + i++); this givs 18.
main() { char *p; p="%d\n"; p++; p++; printf(p-2,300); }
main() { unsigned int i=65000; while(i++!=0); printf("%d",i); }
