quester [9]

Answer and Explanation:

#include <iostream>

#include <string>

#include <time.h>

#include <vector>

using namespace std;

//Takes user info

int user_info(string *name,char *gender){

char G;

cout<<"What is your name?: ";

getline(cin, *name);

cout<<"What is your gender(m/f):";

cin>>G;

cout<<endl;

*gender = tolower(G);

return 0;

}

//Toss coin(part 2)

bool coin_toss(double seed){

double r;

r = (double)seed/(double)RAND_MAX;

//cout<<r;

if (r<0.5) return true;

return false;

}

//check results

float toss_result(vector<char> v,int *h){

int num_heads=0;

int num_toss = v.size();

*h = 0;

for(int i=0;i<num_toss;i++){

if(v[i]=='h'){num_heads++;(*h)++;}

}

return (float)num_heads/(float)num_toss;

}

void show_result(int total_num,int head_num,float ratio){

cout<<"it took you "<<total_num<<" tosses to get 3 heads in a row"<<endl;

cout<<"on average you flipped heads "<<(ratio*100)<<"% of the time"<<endl;

}

int main()

{

string name;

char gender;

string K; //Mr or Mrs

cout<<"Welcome to coin toss! Get 3 heads in row to win!"<<endl;

//part 1

user_info(&name,&gender);

if(gender == 'f') K = "Mrs.";

else K = "Mr.";

cout<<"Try to get 3 heads in a row. Good luck "<<K<<name<<"!"<<endl;

char dummy = getchar();

//part 2

int num_toss;

vector<char> toss_results;//store toss results

bool result;//result of toss

srand(time(0));

while(true){

//cout<<rand()<<endl;

result = coin_toss(rand());

cout<<"Press <enter> to flip"<<endl;

while (1)

{

if ('\n' == getchar())

break;

}

if(result) {toss_results.push_back('h');cout<<"HEAD"<<endl;}

else {toss_results.push_back('t');cout<<"TAIL"<<endl;}

num_toss = toss_results.size();

if(num_toss>=3){

if ((toss_results[num_toss-1] == 'h')&&(toss_results[num_toss-2] == 'h')&&(toss_results[num_toss-3] == 'h')){

break;

}

//part 3

float ratio_head;

int num_of_heads;

//part 4

A user called to inform you that the laptop she purchased yesterday is malfunctioning and will not connect to her wireless netwo

Aloiza [94]

Answer:

B. Have the user press the appropriate function key combination to enable the wireless radio and then attempt to connect to the wireless network.

Explanation:

Every more often than not, users may experience wireless connection problems. How they respond to these issues solely depends on various factors. When a user like this has issues connecting to the network, first on the list of proper troubleshooting procedures is to check whether the wireless adapter or the function key that turns the wireless radio connection on is toggled on. Sometimes the most obvious causes are the hardest to see. The user should check this first because it will save him or her lots of troubleshooting time if the switch was simply physically disabled.

a. displays the sum of all even numbers between 2 and 100 (inclusive). b. displays the sum of all squares between 1 and 100 (inc

LuckyWell [14K]

Answer:

The program required is in the explanation segment.

Explanation:

Program :

import math

# a. displays the sum of all even numbers between 2 and 100 (inclusive).

print("All even numbers from 2 to 100 inclusive ")

sum=0

i=2

while i<=100:

if i %2 ==0:

sum=sum+i

print(i,end=" ")

i=i+1

print("\nThe sum of all even numbers between 2 and 100 (inclusive) :",sum);

#b. displays the sum of all squares between 1 and 100 (inclusive).

print("\nAll squares numbers from 1 to 100 inclusive:")

i=1

sum=0

while i<=100:

print(i*i,end=" ")

i=i+1

sum=sum+(i*i)

print("\n\nThe sum of all squares between 1 and 100 (inclusive) is :",sum)

#c. displays the powers of 2 from 1 up to 256.

print("\nAll powers of 2 from 2 ** 0 to 2 ** 8:")

i=0

while True:

p=math.pow(2,i)

if p>256:

break

print("2 ** ",i," is ",int(p))

i=i+1

#d. displays the sum of all odd numbers between a and b (inclusive), where a and b are inputs

print("\nCompute the sum of all odd integers between two intgers ")

a=int(input("Enter an integer:"))

b=int(input("Enter another integer: "))

count = 0

temp=a

sum=0

while a<=b:

if a%2!=0:

print(a,end=" ")

sum=sum+a

a=a+1

print("\nThe total of the odd numbers from ", temp ," to ", b ,"is",sum)

#e.displays the sum of all odd digits of an input. (For example, if the input is 32677, the sum would be 3 + 7 + 7 = 17.)

print("\nCompute the sum of the odd digits in an integer ")

n=int(input("Enter an integer:"))

count=0

sum=0

temp=n

while n!=0:

rem = n%10

if rem%2!=0:

sum=sum+rem

count=count+1

n=int(n/10)

print("Sum of the odd digits is ",sum)

print("The total of the odd digits in ",temp," is ",count)

NAME SEARCH In the Chap07 folder of the Student Sample Programs, you will find the following files: GirlNames.txt—This file cont

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.")
