main () { char * * p = = “Hello” printf ( “%s” * * p); }

Ans: Garbage or nothing

main () { printf ( “%d%c\n” ); printf ( “%d%c\n” ); }

Ans: Garbage Value

main () { int x = = 5; printf ( “%d%d” x + +, + + x); }

Ans = = 6 6

main () { int x = = 4; printf ( “%d” printf ( “%d %d” x, x) ); }

Ans: 4 4 5

main () { union { int i; char p; struct { int t; char e; char o; }w; }; printf ( “%d\n” sizeof (l) ); }

Ans: 4

main () { int i = = 0, n = = 6; while (n--0); i + = = n; printf ( “%d\n” i); }

Ans: 1

ain () { char a[] = = “Hello” printf ( “%c\n” * a + + ); }

Ans: Error

a = 3, b = 2, c = 1.

What's the value of k?

k = = a< b < c − 1.

Ans: 0

main () { int a = 3; do { printf ( “%d” a); a = -1; } while (a0); }

Ans: 3

It is not “exact” Question; But the given Answers is:

main () { char c = = -32; int i = = -64; unsigned u = = -26; if (ci) printf ( “PASS1” ); if (i < c) printf ( “PASS2” ); else printf ( “FAIL1” ); if (i) printf ( “PASS2” ); else printf ( “FAIL2” ); }

Ans: PASS1 PASS2 PASS1

main () { int i = = 4; switch (i) { case 1: Printf ( “HEllo” ): Case default:// “case” should not come with “default” printf ( “* * * *” ); } }

Ans: Error

main () { int sum = = 0, count; for (count = = 1; sum + = = count) printf ( “%d\t” sum); }

main () { char s = = ‘R’ if (cond (s) ) printf ( “UPPER CASE” ); else printf ( “LOWER CASE” ); }

Ans: UPPER CASE

main () { static int i = = 5; printf ( “%d\t” i--); if (i) main (); }

Ans: 5 4 3 2 1

main () { char * a1 = = “new” * a2 = = “dictionary” * t; swap (a1, a2); printf ( “(%s%s)” a1, a2); t =? a1 =? a2 = = t; printf ( “- (%s%s)” a1, a2); }

swap (char * s1, char * s2) { char * temp; s1 = s2; s2 = s1; temp = s1; }

Ans: (newdictionary) - (dictionarynew)

* p + +?

Ans: Increments Address

main () { int a[] = = { 10, 20, 30, 40, 50}; char * p = = (char * ) a; printf ( “%d” ), * ( (int * ) p + 4); }

Ans: 50
