Set numMatches to the number of elements in userValues (having NUM_VALS elements) that equal matchValue. Ex: If matchValue = 2 a

xenn [34]

Answer:

import java.util.Scanner;

public class FindMatchValue {

public static void main (String [] args) {

final int NUM_VALS = 4;

int[] userValues = new int[NUM_VALS];

int i = 0;

int matchValue = 0;

int numMatches = -99; // Assign numMatches with 0 before your for loop

userValues[0] = 2;

userValues[1] = 2;

userValues[2] = 1;

userValues[3] = 2;

matchValue = 2;

numMatches=0;

for(i=0;i<NUM_VALS;i++)

{

if(userValues[i]==matchValue)//cheking if the array element is equal to match value.

{

numMatches++;

}

System.out.println(numMatches);//printing the matchvalue.

}

Output:-

3

Explanation:

First I have set the value numMatches to 0 before the loop.Then I have user the for loop to iterate over the array.In the for loop I am checking that the array element is equal to the matchValue or not if it is equal then increasing the numMatches by 1.Then at last print the value of numMatches.

Write a code segment that takes an emailaddress stored in the string email and stores theuser name in the string user and the ho

iragen [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

int main() {

string email,username,host;//strings to store email,username,hostname..

cout<<"Enter the email address "<<endl;

cin>>email;//taking input of email address..

bool flag=1;

for(int i=0;i<email.length();i++)//iterating over the string email..

{

if(email[i]=='@')//if @ symbol is encountered make flag 0 skip this iteration.

{

flag=0;

continue;

}

if(flag==1)//add to username if flag is 1.

{

username+=email[i];

}

else//add tom host..

host+=email[i];

}

cout<<"The username is "<<username<<endl<<"The host name is "<<host;//printing the username and hostname..

return 0;

}

Explanation:

I have taken three strings to store the email address entered by user ,username and host to store username and host name respectively.Then I am iterating over the string email if @ is encountered then skip that iteration before that keep adding characters to username string and after that keep adding characters to host.

Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the elemen

Verdich [7]

Answer:

Replace <STUDENT CODE> with

for (i = 0; i < SCORES_SIZE; ++i) {

if(lowerScores.at(i)<=0){

lowerScores.at(i) = 0;

}

else{

lowerScores.at(i) = lowerScores.at(i) - 1;

}

Explanation:

To do this, we simply iterate through the vector.

For each item in the vector, we run a check if it is less than 1 (i.e. 0 or negative).

If yes, the vector item is set to 0

If otherwise, 1 is subtracted from that vector item

This line iterates through the vector

for (i = 0; i < SCORES_SIZE; ++i) {

This checks if vector item is less than 1

if(lowerScores.at(i)<1){

If yes, the vector item is set to 0

lowerScores.at(i) = 0;

}

else{

If otherwise, 1 is subtracted from the vector item

lowerScores.at(i) = lowerScores.at(i) - 1;

}

Also, include the following at the beginning of the program:

<em>#include <vector></em>

Answer:

megapixel refers to the unit of resolution i.e. one million

Explanation:

Interestingly the higher the pixels does not mean higher quality of image, it's more about the camera and it's sensor.

I am a photographer and a licensed drone pilot and have researched the subject to help with camera choice, both DSLR and drone.
