IT\'S COMMENTS as it won\'t be executed but remain in source code

Question 2

What is the output of the following code statements? The compiler saves the first integer at the memory location 4165 and the rest at consecutive memory spaces in order of declaration. Integer is one byte long.
integer a

pointer c, d

a = 30c = &a

c = &a

d = c

a = a + 10

print *c

6 bits means total combinations of bits are 2^6 = 64. That is, 0 to 63. But given data type is signed means -32 to +31 which stores exactly 64 combinations. Now coming to the question, we can not store both 32 and 64. But can store -12, 0.

Question 4

Time: 00:00:00
A language has 28 different letters in total. Each word in the language iscomposed of maximum 7 letters. You want to create a data-type to store a word ofthis language. You decide to store the word as an array of letters. How many bits will you assign to the data-type to be able to store all kinds of words of the language.

1 bit- 2 letters 2 bit-4 letters 3 bit-8 letters 4 bit-16 letters 5 bit-32 letters 28 letters>16 and 28 letters<32 array is of size 7 so, 5*7=35bits

Question 5

Time: 00:00:00
A 10-bit unsigned integer has the following range:

0 to 1000

0 to 1000

0 to 1024

0 to 1024

1 to 1025

1 to 1025

0 to 1023

0 to 1023

2^10=1024 so range of unsigned integer will be 0 to 1023

Question 6

Time: 00:00:00
Parul takes as input two numbers: a and b. a and b can take integer valuesbetween 0 and 255. She stores a, b and c as 1-byte data type. She writes the following code statement to process a and b and put the result in c.
c = a + 2*b
To her surprise her program gives the right output with some input values of a and b, while gives an erroneous answer for others. For which of the following inputs will it give a wrong answer?

a = 10 b = 200

a = 10 b = 200

a = 200 b = 10

a = 200 b = 10

a = 50 b = 100

a = 50 b = 100

a = 100 b = 50

a = 100 b = 50

0 to 255 integers are accepted when a=10 b=200 c =410 > 255 when a=200 b=10 c=220<255 when a=50 b=100 c=250<255 when a=100 b=50 c=200<255 so, option 1 gives wrong output
