(Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of int

Papessa [141]

Answer:

Explanation:

Sorry it is in Java, though you can covert it using converter

public class Exercise {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int positives = 0; // Count the number of positive numbers

int negatives = 0; // Count the number of negative numbers

int count = 0; // Count all numbers

double total = 0; // Accumulate a totol

// Promopt the user to enter an integer or 0 to exit

System.out.print("Enter an integer, the input ends if it is 0: ");

int number = input.nextInt();

if (number == 0) { // Test for sentinel value

System.out.println("No numbers are entered except 0");

System.exit(1);

}

while (number != 0) {// Test for sentinel value

if (number > 0)

positives++; // Increase positives

else

negatives++; // Increase negatives

total += number; // Accumulate total

count++; // Increase the count

number = input.nextInt();

}

// Calculate the average

double average = total / count;

// Display results

System.out.println(

"The number of positive is " + positives +

"\nThe number of negatives is " + negatives +

"\nThe total is total " + total +

"\nThe average is " + average);

}

Programming challenge description: Write a program that, given two binary numbers represented as strings, prints their sum in bi

Lubov Fominskaja [6]

Answer:

The program to this question can be given as:

Program:

#include<iostream> //include header file

using namespace std;

string add(string a, string b) //define add function

{ //declare variable

string result = "";

int sum = 0,k,l;

cahr x;

k= a.size() - 1;

l = b.size() - 1;

while (k>= 0 || l>= 0 || sum == 1) //loop

{

//addition

sum= sum+ ((k >= 0)? a[k] - '0': 0);

sum= sum+ ((l >= 0)? b[l] - '0': 0);

x=sum%2;

result=(x+'0') +result;

// Compute carry

sum =sum/ 2;

// Move to next digits

k--;

l--;

}

return result; //return value

}

int main() //main method

{

string a,b; //string variable

cout<<"Enter first binary digit: "; //message.

cin>>a; //input from user

cout<<"Enter Second binary digit: "; //message.

cin>>b; //input from user

cout <<"Addition :"<<add(a, b)<<endl; //print addition

return 0;

}

Output:

Enter first binary digit: 1101

Enter Second binary digit: 100

Addition :10001

Explanation:

In the above c++ program first, we include the header file. Then we define the add function in the add function we add two binary digits by passing value as arguments. In this function, we define a variable that is used on the addition of binary numbers. In this function we define the loop in the loop we check if two binary number is 1 then it will print 0 and pass 1 as the carry. after performing addition it will return value. In the main function, we take two binary numbers from the user and pass the value to the function and print function return value.

Tems11 [23]

Answer:

Explanation:

I do not have the files listed in the question so I have made two test files with the same names. This code is written in Python, we are assuming that the names on each file are separated by newlines.

f1 = open("GirlNames.txt", 'r')

f1_names = f1.read()

f1_names_list = f1_names.split('\n')

f2 = open("BoyNames.txt", 'r')

f2_names = f2.read()

f2_names_list = f2_names.split('\n')

print(f1_names_list)

print(f2_names_list)

boy_or_girl = input("Would you like to enter a boy or girl name or both: ").lower()

if boy_or_girl == 'boy':

name = input("Enter name: ")

if name in f2_names_list:

print("Yes " + name + " is in the list of most popular boy names.")

else:

print("No, it is not in the list")

elif boy_or_girl == 'girl':

name = input("Enter name: ")

if name in f1_names_list:

print("Yes " + name + " is in the list of most popular girl names.")

else:

print("No, it is not in the list")

elif boy_or_girl == 'both':

girlname = input("Enter Girl name: ")

if girlname in f1_names_list:

print("Yes " + girlname + " is in the list of most popular girl names.")

else:

print("No, it is not in the list")

boyname = input("Enter name: ")

if boyname in f2_names_list:

print("Yes " + boyname + " is in the list of most popular girl names.")

else:

print("No, it is not in the list")

else:

print("Wrong input.")
