Answer:

Hi, for this exercise we have two laws to bear in mind:

Morgan's laws

NOT(А).NOT(В) = NOT(A) + NOT (B)

NOT(A) + NOT (B) = NOT(А).NOT(В)

And the table of the Nand

INPUT OUTPUT

A B A NAND B

0 0 1

0 1 1

1 0 1

1 1 0

Let's start!

Input OUTPUT

A A A NAND A

1 1 0

0 0 1

Input OUTPUT

A B (A NAND B ) NAND (A NAND B )

0 0 0

0 1 0

1 0 0

1 1 1

Input OUTPUT

A B (A NAND A ) NAND (B NAND B )

0 0 0

0 1 1

1 0 1

1 1 1

Explanation:

In the first one, we only need one input in this case A and comparing with the truth table we have the not gate

In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.

In the third case we have that the OR is A + B and we know in base of the morgan's law that:

A + B = NOT(NOT(А).NOT(В))

So, we have to negate the two inputs and after make nand with the two inputs negated.

I hope it's help you.

Write code for a function with the following prototype: /* Addition that saturates to TMin or TMax */ int saturating_add(int x,

Kazeer [188]

Answer:

See explaination

Explanation:

program code.

/* PRE PROCESSOR DIRECTIVES */

#include<stdio.h>

/* PRE-DEFINED VALUES FOR TMAX AND TMIN */

#define TMax 2147483647

#define TMin (-TMax -1)

/* saturating_add(int,int) METHOD IS CALLED HERE */

int saturating_add(int firstNumber, int secondNumber)

{

FOR BETTER UNDERSTANDING, LETS TAKE TEST CASE,

WHERE firstNumber = 5 AND secondNumber = 10

int w = sizeof(firstNumber) << 3;

sizeof(firstNumber) VALUE IS 4, SO USING BINARY LEFT SHIFT OPERATOR TO THREE PLACES,

WE HAVE NOW VALUE 32, ASSIGNED TO w

/* ADDITION IS CALCULATED => 15 */

int addition = firstNumber + secondNumber;

MASK INTEGER VARIABLE IS TAKEN

mask BIT IS LEFT SHIFTED TO 31 PLACES => 2^31 IS THE NEW VALUE

int mask = 1 << (w - 1);

/* FIRST NUMBER MOST SIGNIFICANT BIT IS CALCULATED BY USING AND OPERATOR */

int msbFirstNumber = firstNumber & mask;

/* SECOND NUMBER MOST SIGNIFICANT BIT IS CALCULATED BY USING AND OPERATOR */

int msbSecondNumber = secondNumber & mask;

/* MOST SIGNIFICANT BIT OF ADDITION IS CALCULATED BY USING AND OPERATOR */

int msbAddition = addition & mask;

/* POSITIVE OVERFLOW IS DETERMINED */

int positiveOverflow = ~msbFirstNumber & ~msbSecondNumber & msbAddition;

/* NEGATIVE OVERFLOW IS DETERMINED */

int negativeOverflow = msbFirstNumber & msbSecondNumber & !msbAddition;

/* THE CORRESPONDING VALUE IS RETURNED AS PER THE SATURATING ADDITION RULES */

(positiveOverflow) && (addition = TMax);

(negativeOverflow) && (addition = TMin);

return addition;

}

/* MAIN FUNCTION STARTS HERE */

int main(){

/* TEST CASE */

int sum = saturating_add(5, 10);

/* DISPLAY THE RESULT OF TEST CASE */

printf("The Sum Is : %d\n\n",sum);

In java write a program:A contact list is a place where you can store a specific contact with other associated information such

BigorU [14]

Answer:

import java.util.Scanner;

public class ContactInformation

{

public static String GetPhoneNumber(String[] nameVec, String[] phoneNumberVec, String contactName, int arraySize)

{

for(int i=0;i<arraySize;i++)

{

if(nameVec[i].equals(contactName))

return phoneNumberVec[i];

}

return "Contact doesn't exists!";

}

public static void main(String[] args)

{

int records;

Scanner sc = new Scanner(System.in);

System.out.print("Enter the size of contact List :");

records=sc.nextInt();

String[] contactNameList=new String[records];

String[] phoneNumberList=new String[records];

String contactName;

System.out.println("Enter the contact name and phone number :");

for(int i=0;i<contactNameList.length;i++)

{

contactNameList[i]=sc.next();

phoneNumberList[i]=sc.next();

}

System.out.println("Enter the name of the contact to be searched :");

contactName=sc.next();

System.out.println(GetPhoneNumber(contactNameList,phoneNumberList,contactName,records));

}

Explanation:

In the following the function defined above for getting the contact

number on the basis of contact number provided we are checking the contact name list if we are able to find the contact name and if we did we return the contact number on the same index from the contact number list

which we found in the contact name list.
