1. In case of ordinary int variables

leftmost bit is reserved for sign

rightmost bit is reserved for sign

no bit is reserved for sign

none of these

2. The declarations typedef float hight [100]; height men, women;

define men and women as 100 element floating point arrays

define men and women as floating point variables

define height, men and women as floating point variables

are illegal

3. The statement # include < math.h> is written at the top of a program to indicate

beginning of the program

beginning of the program

that certain information about mathematical library functions are to be included at the begnning of the program

none of these

4. A static variable

cannot be initialized

is initialized once at the commencement of execution and cannot be changed at run time

retains its value throughout the file of the program

is same as an automatic variable but is placed at the head of a program

5. Consider the following statement #define hypotenuse (a, b) sqrt (a*a + b*b); The macro-call hypotenuse (a + 2, b + 3);

finds hypotenuse of triangle with sides a + 2 and b+3

finds square root of (a + 2)2 + (b + 3)2

is meaningless

finds square root of 3*a + 4*b + 5

6. The rule for implicit type conversion in 'C' is

int < unsigned < float < double

unsigned < int < float < double

int < unsigned < double < float

unsigned < int < double < float

7. The variables which can be accessed by all modules in a program, are called

local variables

internal variables

external variable

global variables

8. C programming language by itself provides

input facility

output facility

both input and output facilities

no input and output facilities

9. C programming language provides operations which deal directly with objects such as

strings and sets

lists and arrays

characters, integers, and floating point numbers

all of these

10. In C programming language, if the first and the second operands of operator + are of types int and float, respectively, the result will be of type

int

float

char

long int
