Comments in the codes are used to explain what is happening in the code. It is helpful as if one coder writes code he also writes comments so that other developers can understand easily about the coding logic.

Question 2

Time: 00:00:00
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```

*c points to the value of a; so given a=30 output is 40. Had it been to print only c then the output would have been the address of a that is 4165

check the pic

#### PrepInsta User

A is assigned as 30 initially Then C contain the adress of A Then d stores c which means value at the adress which c holds that means 30.. Then a is updated and become 40.. Hence when *C is printed then value at A is printed..

#### PrepInsta User

Actually *c=*(&a) a=30+10 a=40 There fore a=40

#### PrepInsta User

int a; *c, *d; a = 30; c = &a; //pointer c has the memory location of a i.e 4165 d = c ; //d is 4165 a = a +10; print *c //*c is a defererence pointer which gives the value of the variable to which it is pointing at, so 40 is the answer

output is 40

#### PrepInsta User

#include int main() { int a; int *c, *d; a=30; c = &a; d=c; a=a+10; printf(\"%d\",c); } o/p: 4165 i.e is the address of c but is we print ----- printf(\"%d\",*c); then o/p is : 40

#### PrepInsta User

As c is assigned with address of a,a is updated , so when we print c, updated value of a will be printed. a=30 c=&a a=a+10 /a=40----> c=30 print(*c)

4165

40

4165

#### PrepInsta User

a=30; c=&a; so c=4165; d=4165; c=4165

4165

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.

#### PrepInsta User

how it can be 35. someone pls explain

#### PrepInsta User

In binary, there are only two possibilities- zero and one.  Thus, looking at the powers of 2, we realize that 32 is the closest exponential result of 2 to 28, where 2^5 = 32. Hence, to cover all the possibilities, we need 5 bits at the least. But there are seven letters. Thus, the number of bits we require is 7 * 5 = 35 bits  Read more on Brainly.in - https://brainly.in/question/3672631#readmore

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 = 200 b = 10

a = 200 b = 10

a = 10 b = 200

a = 10 b = 200

a = 100 b = 50

a = 100 b = 50

a = 50 b = 100

a = 50 b = 100

#### PrepInsta User

65000 comes in the range of short (16-bit) which occupies the least memory. Signed short ranges from -32768 to 32767 and hence we should use unsigned short.
