C# MCQ Set 3

1. Select a convenient declaration and initialization of a floating point number:
a) float somevariable = 12.502D
b) float somevariable = (Double) 12.502D
c) float somevariable = (float) 12.502D
d) float somevariable = (Decimal)12.502D

Answer

Answer: c [Reason:] We cannot implicitly convert a “double” number directly to any other datatype.Here, its float we have to add the required datatype to number as :
float somevariable = (float)12.502D;
or
Double somevariable = (Double)12.502D;

2. Number of digits upto which precision value of float datatype is valid ?
a) Upto 6 digit
b) Upto 8 digit
c) Upto 9 digit
d) Upto 7 digit

Answer

Answer: d [Reason:] By definition.

3. Valid Size of float datatype is ?
a) 10 Bytes
b) 6 Bytes
c) 4 Bytes
d) 8 Bytes

Answer

Answer: c [Reason:] By definition.

4. Correct way to define a value 6.28 in a variable ‘pi’ where value cannot be modified ?
a) #define pi 6.28F
b) pi = 6.28F
c) const float pi = 6.28F
d) const float pi
pi = 6.28F

Answer

Answer: c [Reason:] Const is a reserve keyword whenever they are declared with any variables.The value stored in that variable always remain fixed. Any modification done to change value of that variable results in error.Hence, options a, b and d are rejected because value is not declared fixed. Now, for value ‘c’ and ‘d’ only option ‘c’ is correct because for value ‘d’ while declaring a constant variable we need to provide a constant value too as provided in ‘c’. So, option ‘c’ is correct way of declaration of constant variable.

5. Select correct set of code to display the value of given variable ‘c’ as ‘25.302’.

```
a) float a = (double) 12.502f;
```
```
   float b = 12.80f;
```
```
   float c;
```
```
   c = (float) a + b;
```
```
   Console.Writeline(c);
```
```
   Console.ReadLine();
```
```
b) float a = 12.502D;
```
```
   float b = 12.80f;
```
```
   float c;
```
```
   c = a + b;
```
```
   Console.WriteLine(c);
```
```
   Console.ReadLine();
```
```
c) double a = 12.502;
```
```
   float b = 12.802f;
```
```
   float c;
```
```
   c = (float)a + b;
```
```
   Console.WriteLine(c);
```
```
   Console.ReadLine();
```
```
d) double a = (float) 12.502f;
```
```
   float  b = 12.80f;
```
```
   float  c;
```
```
   c = a + b;
```
```
   Console.WriteLine(c);
```
```
   Console.ReadLine();
```

Answer

Answer: c [Reason:] Expression c = (float) a + b.

8. Why does a float variable stop incrementing at number ‘16777216’ in given code in C#?

```
 float a = 0 ;
```
```
 while (true)
```
```
 {
```
```
     a++;
```
```
     if (a > 16777216)
```
```
     break;
```
```
 }
```

a) Sign and Exponent for ‘16777217’ is same as for ‘16777216’
b) Mantissa is different for ‘16777216’ and ‘16777217’
c) Sign and Exponent for ‘16777217’ is different from ‘16777216’
d) None of the mentioned

Answer

Answer: b [Reason:] 16777216 is exactly 224, and would be represented as 32-bit float like so:
sign = 0 (positive number)
exponent = 24 (stored as 24 + 127 = 151 = 10010111)
mantissa = . 0
As 32 bits floating-point representation: 0 10010111 00000000000000000000000
Therefore: Value = (+ 1) * 2 ^ 24 * (1. 0 + . 0) = 2 ^ 24 = 16777216
Now let’s look at the number 16777217, or exactly 224 + 1:
sign and exponent are the same.
Mantissa should have to be exactly 2-24 so that (+ 1) * 2 ^ 24 * (1. 0 + 2 ^-24) = 2 ^ 24 + 1 = 16777217 and here lies the actual problem . The mantissa cannot have the value 2-24 because it only has 23 bits, so the number 16777217 just cannot be represented with the accuracy of 32-bit floating points numbers.

9. Select the output of the following set of code ?

```
static void Main(string[] args)
```
```
{
```
```
    int x = 1;
```
```
    float y = 2. 4f;
```
```
    short z = 1;
```

    Console. WriteLine((float) x + y * z - (x + = (short) y) );

```
    Console. ReadLine();
```
```
}
```

a) 0.4000004

10. A float occupies 4 bytes. If the hexadecimal equivalent of these 4 bytes are A, B, C and D, then when this float is stored in memory in which of the following order do these bytes gets stored ?
a) ABCD
b) DCBA
c) 0 * ABCD
d) Depends on big endian or little endian architecture

Answer

Answer: d [Reason:] “Little Endian” means that the lower-order byte of the number is stored in memory at the lowest address, and the high order byte at the highest address. For example, a 4 byte Integer
ABCD will be arranged in memory as follows:
Base Address + 0 Byte 0 .
Base Address + 1 Byte 1 .
Base Address + 2 Byte 2 .
Base Address + 3 Byte 3 .
Intel processors (those used in PC’s) use “Little Endian” byte order.
“Big Endian” means that the high-order byte of the number is stored in memory at the lowest address, and the low-order byte at the highest address. The same 4 byte integer would be stored as:
Base Address + 0 Byte 3 .
Base Address + 1 Byte 2 .
Base Address + 2 Byte 1 .
Base Address + 3 Byte 0 .

own function
d) %Ox for smallcase letters and %OX for capital letters

Answer

Answer: c [Reason:] Explained in answer itself.

```
```
       {
```
```
           switch (i)
```
```
           {
```
```

```

               Console.WriteLine("zero");

```
               break;
```
```
           }
```
```
           if (i > 0)
```
```
               Console.WriteLine("A");
```
```
           else if (i < 0)
```
```
               Console.WriteLine("B");
```
```
       }
```
```
       Console.ReadLine();
```
```
   }
```

a) B B zero A A A
b) B zero A A A
c) B B B zero A A A
d) A A A zero B B B

Answer

Answer: c [Reason:] for i =-3,-2,-1 statement executed as B.for i = 0,it is zero and for i =1,2,3 again statement printed as A seperately for each value of i.
Output: B B B zero A A A.

12. Select the output for the following set of code :

```
  static void Main(string[] args)
```
```
  {
```
```
      int i, j;
```

      for (i = 1, j = i; i <= 3 && j >= 0; i++, j--)

```
      {
```
```
          if (i == j)
```
```
              continue;
```
```
          else
```
```
              Console.WriteLine(j);
```
```
      }
```
```
      Console.ReadLine();
```
```
  }
```

a) i = 0, j = 1;
b) i = 1, j = 0;
c) j = 0;
d) None of the mentioned

Answer

Answer: c [Reason:] Since for i = 1, j = 1 and 1 <= 3 also 1 >= 0 we had i == j.But after i++ and j–. The initial value of ‘j’ which is ‘0’ as j– preferred other than value of ‘j’ in i = j.
Output:j = 0.

13. Select the output for the following set of code :

```
 static void Main(string[] args)
```

```
     Console.ReadLine();
```
```
 }
```

a) -9 -8 -7 -6 -5 -4 -3 -2 -1
b) -10 -9 -8 -7 -6 -5 -4 -3 -2
c) -10 -9 -8 -7 -6 -5 -4 -3 -2 -1
d) -8 -7 -6 -5 -4 -3 -2 -1

Answer

Answer: c [Reason:] For first value of i = -10.Condition is executed until i!=0.
Output: -10 -9 -8 -7 -6 -5 -4 -3 -2 -1.
