Answer:

a) range check

Explanation:

Validation can be defined as an automatic computer check that is designed to ensure any data entered is sensible, consistent, feasible and reasonable.

Basically, there are five (5) main validation methods and these includes;

I. Presence check: checks that the user enters (inputs) data into the field. It ensures a field isn't accidentally left blank.

II. Length check: checks that the data entered isn't too short or too long. It ensures that the data meets the minimum characters.

III. Type check: checks that the data entered is in the right format. For example, string, integer, float, etc.

IV. Check digit: checks that the digit entered is acceptable and consistent with the rest of the digits.

V. Range check: checks that the data entered is between the accepted lower (minimum) and upper (maximum) level.

Hence, range check is a validation type you would use to check that numbers fell within a certain range.

For example, 0 < x > 1000 is a range check.

The area of a rectangle is the rectangle's length times its width.
aliya0001 [1]

Answer:

Following are program to this question:

#include <iostream> //defining header file  

using namespace std;  

int main() //defining main method

{

   double len1,len2,wid1,wid2,area1,area2; //defining double variable

   cout << "Enter first rectangle length: "; //print message

   cin >> len1;//input first rectangle length value

   cout << "Enter first rectangle width: ";//print message

   cin >> wid1; //input first rectangle width value

   area1 = len1*wid1; //calculate area and holds its value  

   cout << "Enter second rectangle length: ";//print message

   cin >> len2; //input second rectangle length value

   cout << "Enter second rectangle width: ";//print message

   cin >> wid2; //input second rectangle width value

   area2 = len2*wid2; //calculate area and holds its value  

   if(area1 > area2) //check condition area1 value is greater then area2

   {

    cout << "First rectangle area value is greater";//print message

   }

   else if(area2 > area1)//check condition area2 value is greater then area1

   {

       cout << "Second rectangle area value is greater";//print message

   }

   else //else block

   {

       cout << "both rectangle area is same";//print message

   }

   return 0;

}

Output:

Enter first rectangle length: 3

Enter first rectangle width: 5

Enter second rectangle length: 5

Enter second rectangle width: 3

both rectangle area is same

Explanation:

The description of the above program can be described as follows:

  • In the given code, the double variable is declared, which is "len1, len2, wid1, wid2, area1, and area2". In the next line, a message is a print, that accepts "len1 and wid1" value in the next line, the area variable is used that calculates area1.
  • In the next step, the "len2 and wid2"  variable is used, that accepts values and calculates its area, and in the next line, the conditional statement is used that checks its value.
  • In the if the block it uses both area1 and area2 value, that checks area1 is greater then area2, it is will print first rectangle area is greater.  
  • Otherwise, it will go to else if block, that checks area2 is greater then area1, it is will print second rectangle area is greater.  In the else section, it will print both equal areas.

Write a program that accepts any number of homework scores ranging in value from 0 through
Dimas [21]

Answer:

This program is written in Java programming language.

It uses an array to store scores of each test.

And it also validates user input to allow only integers 0 to 10,

Because the program says the average should be calculated by excluding the highest and lowest scores, the average is calculated as follows;

Average = (Sum of all scores - highest - lowest)/(Total number of tests - 2).

The program is as follows (Take note of the comments; they serve as explanation)

import java.util.*;

public class CalcAvg

{

public static void main(String [] args)

{

 Scanner inputt = new Scanner(System.in);

 // Declare number of test as integer

 int numTest;

 numTest = 0;

 boolean  check;

  do

  {

   try

   {

     Scanner input = new Scanner(System.in);

    System.out.print("Enter number of test (1 - 10): ");

    numTest = input.nextInt();

    check = false;

    if(numTest>10 || numTest<0)

     check = true;

   }

   catch(Exception e)

    {

     check = true;

   }

  }

  while(check);

  int [] tests = new int[numTest];

//Accept Input

for(int i =0;i<numTest;i++)

{

System.out.print("Enter Test Score "+(i+1)+": ");

tests[i] = inputt.nextInt();

}

           //Determine highest

           int max = tests[0];

           for (int i = 1; i < numTest; i++)

           {

               if (tests[i] > max)

               {

                   max = tests[i];

               }

           }

           //Determine Lowest

           int least = tests[0];

           for (int i = 1; i < numTest; i++)

           {

               if (tests[i] < least)

               {

                   least = tests[i];

               }

           }

           int sum = 0;

           //Calculate total

           for(int i =0; i< numTest;i++)

           {

               sum += tests[i];

           }

           //Subtract highest and least values

           sum = sum - least - max;

           //Calculate average

           double average = sum / (numTest - 2);

           //Print Average

           System.out.println("Average = "+average);

           //Print Highest

           System.out.println("Highest = "+max);

           //Print Lowest

           System.out.print("Lowest = "+least);

}

}

Write a program that will predict the size of a population of organisms. The program // should ask the user for the starting num
nordsb [41]

Answer:

Following are the program in the C++ Programming Language:

#include <iostream>

using namespace std;

int main() {

 float starting, average;

 int num;

 std::cout <<"Enter starting number of the organisms: ";

 while(!(std::cin >> starting)|| starting < 2){

   std::cout<<"starting number must be greater than 2\n";

   std::cout <<"Enter starting number of the organisms: ";

   std::cin.clear();

   std::cin.ignore(123,'\n');

 }

 std::cout <<"Enter the average of daily population is increase %: ";

 while(!(std::cin >> average)|| average < 0){

   std::cout<<"Average must be greater than 0\n Enter average";

   std::cin.clear();

   std::cin.ignore(123,'\n');

 }

   average *= .01;

 std::cout <<"Enter the number of days: ";

 while(!(std::cin >> num)|| num < 1){

   std::cout<<"Number of days no be less than 1\n" <<"Enterthe number of days\n";

   std::cin.clear();

   std::cin.ignore(123,'\n');

 }

 for(int i=0; i<num; i++){

   std::cout<<"population size of day"<<(i+1);

   std::cout<<": "<<starting<<std::endl;

   starting +=(starting*average);

 }

 return 0;

}

<u>Output</u>:

Enter starting number of the organisms: 4

Enter the average of daily population is increase %: 5

Enter the number of days: 4

population size of day1: 4

population size of day2: 4.2

population size of day3: 4.41

population size of day4: 4.6305

Explanation:

Here, we define header file "<iostream>" and namespace "std".

  • Then, we define the main() inside it, we set two float data type variable i.e., "starting", "average" and set an integer data type variable i.e., "num".
  • Then, we print a message and after that, we set the while loop for get input from the user in variable "starting" and pass the condition inside loop we print message than clear cin and ignore 123 then, we again do this to get  input from user in variable "average".
  • Then, we set the for loop and pass the condition inside the loop print the size of the day then print the value of "starting" after that we multiply.
  • Finally, we return 0 and close the main function.
