Can anyone help me figure out why my if statements are not executing properly? When the program executes with 7 as the value for

num it should be executing the first line, but instead it goes to the third and displays, " a single digit."
public static String numberInfo(int num){
//TODO student
String numInfo;

if (num == 7) {
numInfo = "lucky sevens!";
}
if (num == 42) {
numInfo = "the answer to life the universe and everything.";
}
if (num < 10) {
numInfo = "a single digit.";
}
else {
numInfo = "a positive number.";
}
return numInfo;
}

Answer:

For the value of 7 of num, there are actually two if statements that are true and their contained code is executed.

So your line numInfo = "lucky sevens!"; is executed for sure, but then numInfo gets overwritten with by numInfo = "a single digit.";

To fix it, you have to decide how you want the program to behave, since technically, both numInfo's are equally correct.

- if you want to execute at most one if condition, chain them together like if (...) { ... } else if(...) { ... } etc.

- if you want to return multiple numInfo's, turn it into a collection where you add strings

Identify the correct XHTML syntax for inserting an image as a hyperlink from the options provided. A. book.gif B. C. D.
mariarad [96]

Answer:

The Correct syntax for inserting an image as hyperlink is given in explanation section

Explanation:

To make an image act as a hyperlink, place the image element within the HTML anchor "<a></a>"  element.

The syntax of inserting image hyperlink in XHTML is given below.

<a href = "link_that_can_be_accessible"><img src="source of image" alt="display name if image not shown in the browser" border="0"/></a>

for example lets insert image as hyperlink

<a href="ajax.html"><img src="logo.gif" alt="AJAX" border="0" /></a>

The default appearance is a blue border around the image. Specifying border="0" removes the border around the image.

if you want to insert image from another folder then the image hyperlink looks like this:

<a href="ajax.html"><img src="/images/html5/logo.gif" alt="AJAX" border="0" /></a>

If you want to insert image from another server then image hyper link looks like this:

<a href="ajax.html"><img src="https://www.myExample.com/images/html5/logo.gif" alt="AJAX" border="0" /></a>

Assume you are given a boolean variable named isNegative and a 2-dimensional array of ints that has been created and assigned to
Anon25 [30]

Answer:

#include <iostream>

using namespace std;

int main(){

   int rows, cols;

   bool isNegatives;

   cout<<"Rows: ";

   cin>>rows;

   cout<<"Columns: ";

   cin>>cols;

   int a2d[rows][cols];

   for(int i =0;i<rows;i++){

   for(int j =0;j<cols;j++){

       cin>>a2d[i][j];}    }

   int negatives, others = 0;

   for(int i =0;i<rows;i++){

   for(int j =0;j<cols;j++){

       if(a2d[i][j]<0){

           negatives++;}

       else{

           others++;}}    }

   if(negatives>others){

       isNegatives = true;}

   else{

       isNegatives = false;}

   cout<<isNegatives;  

   return 0;

}

Explanation:

For clarity and better understanding of the question, I answered the question from the scratch.

This line declares number of rows and columns

   int rows, cols;

This line declares the Boolean variable

   bool isNegatives;

This line prompts user for rows

   cout<<"Rows: ";

This line gets the number of rows

   cin>>rows;

This line prompts user for columns

   cout<<"Columns: ";

This line gets the number of columns

   cin>>cols;

This line declares the array

   int a2d[rows][cols];

This line gets user input for the array

<em>    for(int i =0;i<rows;i++){</em>

<em>    for(int j =0;j<cols;j++){</em>

<em>        cin>>a2d[i][j];}    }</em>

This line declares and initializes number of negative and others to 0

   int negatives, others = 0;

The following iteration counts the number of negatives and also count the number of non negative (i.e. others)

<em>    for(int i =0;i<rows;i++){</em>

<em>    for(int j =0;j<cols;j++){</em>

<em>        if(a2d[i][j]<0){</em>

<em>            negatives++;}</em>

<em>        else{</em>

<em>            others++;}}    }</em>

This checks of number of negatives is greater than others

   if(negatives>others){

If yes, it assigns true to isNegatives

       isNegatives = true;}

   else{

If otherwise, it assigns false to isNegatives

       isNegatives = false;}

This prints the value of isNegatives

   cout<<isNegatives;

How can touch typing quickly but accurately improve your earnings (the money you can make)
AnnyKZ [126]

Doing so would not only increase your productivity potential / but also increase your productivity STANDARDS for certain jobs (e.g. data entry; secretarial work), which is a direct skill that is valuable to employers.  Furthermore, if you work in a a secretarial job, this would allow you to accomplish tasks such as "touch typing" a lot faster (without sacrificing quality) —  allowing you more time to accomplish other tasks, making you more efficient and even promotable in terms of pay raise and in terms of promotable to other positions with higher earnings — and even teach new staff members.

What is wrong with each of the following?
ankoles [38]

Answer:

The answer to this question is given below in the explanation section

Explanation:

shoNum + shoNum2 = shoTotal

in this code statement,  the order of operation is wrong because the calculation in programming always done at the right side of dependent variables.  so the correct statement of code is

<em> shoTotal = shoNum + shoNum2;</em>

shoNum = 10 * 4

This statement is programmatically correct, because the ShoNum value becomes 40 after performing the multiplication operation on its assigned value  (10 multiply by 4). However, it is noted that the empty space mostly ignored by the compiler. So, the correct is <em>shoNum = 10*4;</em>

Dim decPrice As Decimal = "$4.99"

The dollar sign is appeared in along with its value. So, if you assign value to a decimal variable, you need to assign only digit value (do not mix value with symbol or text) and also do not put quotation marks around value, if you put quotation marks around value then this value will be consider as a text value.

So, the correct statement is :

<em>Dim decPrice As Decimal = 4.99;</em>

shoCube= (shoSide)3

In this statement, cube is calculated of shoSide variable, mathematically it is right, but programmatically it is incorrect. Because, you missed the multiplication operation (*) between the operand shoSide and 3. it should

be as  shoSide raise to power 3.

the correct statement is : shoCube = (shoSide * shoSide *shoSide);
