In 4-bit two's complement representation, what is the binary encoding of the number -5?

Katena32 [7]

Answer:

a) 1011

Explanation:

In 4 bit two's complement representation, the first bit is the sign bit.

If the sign bit is 1, the number is negative.

If the sign bit is 0, the number is positive.

What is the magnitude of the sign bit?

In n-bit two's complement representation, the magnitude of the sign bit is:

$2^{n-1}-1$

So, in 4-bit two's complement representation, the magnitude of the sign bit is:

$2^{4-1}-1 = 8$

Since the number is negative, the value of this bit is -8.

The other bits are magnitude bits, positive.

We have that the sum of these bits must be -5, and we already have -8. So what should be the value of these last 3 bits?

First, i am going to solve this equation to find the decimal value of the last three bits.

$-5 = -8 + x$

$x = 3$

So, the last three bits are:

$3_{10} = (011)_{2}$

The binary encoding of the number -5 is:

a) 1011

Write a C# Console application that converts a mile into its equivalent metric kilometer measurement. The program asks the user

zzz [600]

Answer:

Following are the program in c#

using System; // namespace system

using System.Collections.Generic; // namespace collection

using System.Linq;

using System.Text;

namespace test // namespace

{

class Program1 // class

{

static void Main(string[] args) // Main function

{

double nMiles, nKm;

Console.Write("Enter Value In Miles : ");

nMiles =Convert.ToDouble(Console.ReadLine());

nKm = (nMiles / 0.62137);

Console.WriteLine("Output:");

Console.WriteLine("Value In Miles :" + nMiles);

Console.WriteLine("Value In KM :" + nKm);

Console.Read();

}

Output:

Case A-

Enter Value In Miles : 10

Value In Miles : 10

Value In KM : 16.09347

Case B-

Enter Values In Miles : 3.25

Value In Miles : 3.25

Value In KM : 5.230378

Explanation:

Here we take a input value in "nMiles" variable and converted into a Km. that will stored in "nkm" variable . To convert miles into km we use calculative formula Km=(miles/0.62137). This formula convert the entered value into km and finally print the value of miles and km miles variable.
