Q.3 printf (“%d”, printf (“tim”));
(A) results in a syntax error (B) outputs tim3
(C) outputs garbage (D) outputs tim and terminates abruptly
Ans:B

printf statement will print tim3, “tim” due to inner printf statement and 3 as length due to

Q.4 Output of the following program fragment is
x = 5;
y = x++;
printf(“%d%d”, x, y);
(A) 5, 6 (B) 5, 5
(C) 6, 5 (D) 6, 6
Ans:C

x is incremented by 1 and before that increment the value is assigned to y so value of x=6 and
y=5.

Q.5 The value of an automatic variable that is declared but not initialised will be
(A) 0 (B) -1
(C) unpredictable (D) none of these
Ans:C

Q.6 Consider the following program
main ( )
{ float a = 0.5, b = 0.7;
if (b < 0.8)
if (a < 0.5) printf (“ABCD”);
else printf (“PQR”);
else printf (“JKLF);
}
The output is
(A) ABCD (B) PQR
(C) JKLF (D) None of these
Ans:B

Since b=0.7<0.8, the control goes to second “if” statement where (a<0.5) is false to printf
statement in else part executed printing “PQR”
