You are part of a development team that needs to adopt an integrated development environment tool to increase programmer product

ivity. The team narrowed the options down to two. One is open-source; the other will require an expensive site license. The tool you choose must be reliable, stable and well maintained. Which of the following could be a disadvantage for you to choose open-source, and thus a compelling enough reason to purchase the licensed software instead of using the open-source solution?
A. Your developers will have ready access to the source code.
B. The open-source solution is in the public domain.
C. The code for the open-source solution can be viewed by a community of open-source developers.
D. Maintenance of an open-source solution relies on developers who volunteer to work on the code.

Write a program in C++ to implement bubblesort using the swap function ?
marishachu [46]

C++ program for implementation of Bubble sort  

#include <bits/stdc++.h>  

using namespace std;  

 void swap(int *x, int *y)  /*Defining Swap function of void return type*/

{  

  int temp = *x;  //Swaping the values  

   *x = *y;  

   *y = temp;  

}  

void bubbleSort(int array[], int n) /*Defining function to implement bubbleSort  */

{  

  int i, j;  

  for (i = 0; i < n-1; i++)      

      for (j = 0; j < n-i-1; j++)  /*The last i components are already in location  */

      if (array[j] > array[j+1])  

          swap(&array[j], &array[j+1]);  //Calling swap function

}  

int main()  //driver function

{  

   int array[] = {3, 16, 7, 2, 56, 67, 8}; //Input array  

   int n = sizeof(array)/sizeof(array[0]);  //Finding size of array

   bubbleSort(array, n); //Function calling  

   cout<<"Sorted array: \n";  

   for (int i = 0; i < n; i++)  //printing the sorted array

       cout << array[i] << " ";  

   cout << endl;  

 return 0;  

}  

<u>Output</u>

Sorted array:  

2 3 7 8 16 56 67

The following code does not work as intended. It is meant to input two test grades and return the average in decimal format:
vredina [299]

Answer:

Type casting error

Explanation:

Logically, the program is correct and it is expected to return the average value. However, test1 and test2 are int values and when you applies any algebraic expression on Int, it will result into Int.

So, in this part (test1 + test2 )/2, two integers are adding and the final result is still an integer and this part will act as an integer even if you multiple or divide with any external number.

For example,

test1 = 4

test2 = 5

test1 + test2 = 9

Now, if you divide it by 2, it will still react as an integer portion. So, 9/2 would result in 4 instead of 4.5. All the calculation is done on the right side before assigning it to a double variable. Therefore, the double variable is still getting the int value and your program is not working correctly.

The solution is to typecast the "(test1 + test2 )/2" portion to double using Double.valueOf(test1 + test2)/2 ;

I have also attached the working code below.

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

 System.out.println("Hello World");

 Scanner scan = new Scanner (System.in);

 int test1 = scan.nextInt();

       int test2 = scan.nextInt();

       double average = Double.valueOf(test1 + test2)/2 ;

       System.out.println("Answer: " + average);

}

}
