Q.1 Literal means<\/strong>
(A) a string. (B) a string constant.
(C) a character. (D) an alphabet.
Ans:B<\/strong><\/p>\n

Q.2 Choose the correct answer<\/strong>
(A) Casting refers to implicit type conversion.
(B) Coercion refers to implicit type conversion.
(C) Casting means coercion.
(D) Coercion refers to explicit type conversion.
Ans:B<\/strong><\/p>\n

Q.3 printf (\u0393\u00c7\u00a3%d\u0393\u00c7\u00a5, printf (\u0393\u00c7\u00a3tim\u0393\u00c7\u00a5));<\/strong>
(A) results in a syntax error (B) outputs tim3
(C) outputs garbage (D) outputs tim and terminates abruptly
Ans:B<\/strong><\/p>\n

printf statement will print tim3, \u0393\u00c7\u00a3tim\u0393\u00c7\u00a5 due to inner printf statement and 3 as length due to
outer printf statement.<\/em><\/p>\n

Q.4 Output of the following program fragment is
x = 5;
y = x++;
printf(\u0393\u00c7\u00a3%d%d\u0393\u00c7\u00a5, x, y);<\/strong>
(A) 5, 6 (B) 5, 5
(C) 6, 5 (D) 6, 6
Ans:C<\/strong><\/p>\n

x is incremented by 1 and before that increment the value is assigned to y so value of x=6 and
y=5.<\/em><\/p>\n

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

Q.6 Consider the following program
main ( )
{ float a = 0.5, b = 0.7;
if (b < 0.8)
if (a < 0.5) printf (\u0393\u00c7\u00a3ABCD\u0393\u00c7\u00a5);
else printf (\u0393\u00c7\u00a3PQR\u0393\u00c7\u00a5);
else printf (\u0393\u00c7\u00a3JKLF);
}
The output is<\/strong>
(A) ABCD (B) PQR
(C) JKLF (D) None of these
Ans:B<\/strong><\/p>\n

Since b=0.7<0.8, the control goes to second \u0393\u00c7\u00a3if\u0393\u00c7\u00a5 statement where (a<0.5) is false to printf
statement in else part executed printing \u0393\u00c7\u00a3PQR\u0393\u00c7\u00a5<\/em><\/p>\n

Q.7 The following program fragment
int *a;
*a = 7;<\/strong>
(A) assigns 7 to a (B) results in compilation error
(C) assigns address of a as 7 (D) segmentation fault
Ans:D<\/strong><\/p>\n

Q.8 A pointer variable can be<\/strong>
(A) passed to a function as argument.
(B) changed within function.
(C) returned by a function.
(D) assigned an integer value.
Ans:C<\/strong><\/p>\n

Q.9 \u0393\u00c7\u00ffC\u0393\u00c7\u00d6 is often called a<\/strong>
(A) Object oriented language (B) High level language
(C) Assembly language (D) Machine level language
Ans:B<\/strong><\/p>\n

Q.10 The loop in which the statements within the loop are executed at least once is called<\/strong>
(A) do-while (B) while
(C) for (D) goto
Ans:A<\/strong><\/p>\n

Q.11 The control automatically passes to the first statement after the loop in<\/strong>
(A) continue statement (B) break statement
(C) switch statement (D) if statement
Ans:B<\/strong><\/p>\n

Q.12 A self contained block of statements that perform a coherent task of some kind is called a<\/strong>
(A) Monitor (B) Function
(C) Program (D) Structure
Ans:B<\/strong><\/p>\n

Q.13 Recursion is sometimes called<\/strong>
(A) Circular definition (B) Complex definition
(C) Procedure (D) Union
Ans:A<\/strong><\/p>\n

Q.14 Unsigned integer occupies<\/strong>
(A) Two bytes (B) Four bytes
(C) One byte (D) Eight bytes
Ans:B<\/strong><\/p>\n

Q.15 Each C preprocessor directive begins with<\/strong>
(A) # (B) include
(C) main() (D) {
Ans:A<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
