The ____ operator executes one of two expressions based on the results of a conditional expression. Group of answer choices

Mars2501 [29]

Corrected or Complet Question

The ____ operator executes one of two expressions based on the results of a conditional expression.

a. .

b. ( )

c. ,

d. ?:

Answer:

(d) ? :

Explanation:

The ternary operator (? :) is an operator that executes one out of two expressions based on the results of a conditional expression. It is a faster or shorthand way of writing an if ... else statement. The operator checks the conditional expression and depending on whether it is true or false, one of its two statements will be executed. For example:

String correct = (4 < 5) ? "yes" : "no" ;

In the code above,

i. the conditional statement is (4 < 5) and this will be tested for to return true or false.

ii. the first expression (the one after the ?) is "yes" which will be executed if the conditional statement returns true.

iii. and the second expression (the one after the : ) is "no" which will be executed if the conditional statement returns false.

Therefore, since the conditional expression returns true for 4 < 5, the first expression will be executed. i.e "yes". This means that the String variable <em>correct </em> will have a value of "yes".

Write a C++ program that manage the student’s grades. Starting with a fixed number of students (use 10 for simplicity) the user

BigorU [14]

Answer:

#include <iostream>

using namespace std;

float findAverage(double grades[], int numOfgrades) {

float sum = 0;

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

sum += grades[i];

}

return (sum / numOfgrades);

}

char findLetterGrade(double grades[], int numOfgrades) {

char letter;

if(findAverage(grades, numOfgrades) >= 90 && findAverage(grades, numOfgrades) <= 100)

letter = 'A';

else if(findAverage(grades, numOfgrades) >= 80 && findAverage(grades, numOfgrades) <= 89)

letter = 'B';

else if(findAverage(grades, numOfgrades) >= 70 && findAverage(grades, numOfgrades) <= 79)

letter = 'C';

else if(findAverage(grades, numOfgrades) >= 60 && findAverage(grades, numOfgrades) <= 69)

letter = 'D';

else if(findAverage(grades, numOfgrades) >= 0 && findAverage(grades, numOfgrades) <= 59)

letter = 'F';

return letter;

}

int main()

{

int numOfgrades, grade;

for (int i = 0; i < 10; i++) {

cout<<"Enter the number of grades for student #" << i+1 <<": ";

cin >> numOfgrades;

double grades[numOfgrades];

for (int j = 0; j < numOfgrades; j++) {

cout<<"Enter the grade" << j+1 <<" for student #" << i+1 <<": ";

cin >> grade;

grades[j] = grade;

}

cout << "Student #" << i+1 << " got " << findLetterGrade(grades, numOfgrades) << endl;

}

return 0;

}

Explanation:

Create a function named findAverage that takes two parameters, grades array and numOfgrades

Inside the function, create a for loop that iterates through the grades and calculates the sum of the grades. Then, return the average, sum/numOfgrades

Create another function named findLetterGrade that takes two parameters, grades array and numOfgrades

Inside the function, check the average grade by calling the findAverage() function. Set the letter grade using the given ranges. For example, if the result returned from findAverage() function is between 80 and 89, set the letter to 'B'. Then, return the letter.

In the main:

Create a for loop that iterates for each student, in this case 10 students. Inside the loop:

Ask the user to enter the number of grades for student. Using this value, create a grades array.

Create another for loop (inner for loop) that will set the grades array using the values entered by the user.

When the inner loop is done, call the findLetterGrade() function passing the grades array and numOfgrades as parameter and print the result

What allows you to set up a web page wherein objects change (appear, disappear, move, morph).

ololo11 [35]

You can set up a web page where objects change where they, appear, disappear, move, morph using TIMELINE.

Explanation:

A timeline is presentation of a sequence of events along a drawn line that enables the reader to quickly understand relationships relating to or limited by time.
A website project timeline should list the most important milestones that represent the major stages of creating the website.
A timeline can also be used in a web page to change objects within.
Morphing involves automatically matching the basic look and feel of a website to cognitive styles.
Each stage should be given a set length of time that corresponds to its size and complexity. There is a set of objectives that need to be accomplished in order to complete each stage which help the web page become a reality.
Effects can make an object appear, disappear, morph or move. They can change an object's size or color

When a class implements in interface, it must ________ Group of answer choices overload all of the methods listed in the interfa

Lilit [14]

Answer:

provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified

Explanation:

I am assuming the programming language is Java. Actually, none of the answers are 100% correct, but this one is the only one that is partially correct. The reason is the class implementing an interface can be abstract, and in this case it may not provide ALL nondefault methods.
