1. 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

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

local variables

internal variables

external variable

global variables

3. C programming language by itself provides

input facility

output facility

both input and output facilities

no input and output facilities

4. 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

5. 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

6. The value of ab if ab & 0 x 3f equals 0 x 27 is

047

0 x 0 f

0 x f3

0 x 27

7. If the declaration unsigned c:5; is replaced by unsigned : 6; then

it results in a syntax error

it is meaningless

compiler will give a new name for the field

none of these

8. int i = 5; is a statement in a C program.

during execution, value of i may change but not its address

during execution both the address and value may change

repeated execution may result in different addresses for i

i may not have an associated address

9. The program fragment int i = 263 ; putchar (i) ; prints

263

ASCII equivalent of 263

rings the bell

garbage

10. Printing a character as an integer

results in the printing of a negative integer

always prints a positive integer

prints a value that is implementation dependent

none of these
