**Prerequisite :** Decision making in C

**Question 1**

**OPTIONS: **

a)Segmenation fault

b)Compilation error

c)Print 1 Infinite time

d)Both a & c

OUTPUT:(d)Both a & c

**Explanation: **

We call the main method again and again by 1 because we use post-increment. At certain time stack frame will full means segmentation fault occurs.

**Question 2**

**OPTIONS: **

a)mannu is Crazy

b)paul is crazy

OUTPUT:(b)paul is crazy

**Explanation: **

Here ,comparision between long int and unsigned long int generally which is not possible.

Now,long int is promoted to unsigned long int whose value will be

(2^size_of_unsigned_long_int)-1.

**Question 3**

**OPTIONS: **

a)Hello 3

b)Hello 0

c)Geeksforgeeks 0

d)Geeksforgeeks 3

OUTPUT:(d) Geeksforgeeks 0

**Explanation: **Atfirst zero will assign in ‘i’ then comma operator returns the last value which is 3 and condition becomes true.

**Question 4**

**OPTIONS: **

a)Hello 3

b)Geeksforgeeks 0

c)Hello 0

d)Geeksforgeeks 3

OUTPUT:(c) Hello 0

**Explanation: **Priority of parenthesis bracket is greater than equal to(=) operator , So atfirst comma operator return the last value which is zero(0) and then equal to(=) operator assign 0 to ‘i’ and condition becomes flase.

**Question 5**

**OPTIONS: **

a)Compilation error

b)C++

c)C

OUTPUT:(C)C

**Explanation: **

a = 0.7 is rounded to 0.699999988

and the constant 0.7 is as 0.69999999999

so a<0.7 is true so it print "c"

but in case of 0.8

a = 0.800000011 and

constant 0.8 is 0.8000000000000000
