You will write a program that uses a multidimensional array having 3 rows and 8 columns and sorts each of the rows using both a bubble sort and a selection sort.
You must declare the array inside of main. You will have a for loop containing the calls to bubbleSort and selectionSort. You need to pass into function bubbleSort and selectionSort the following: 1) each column of the multidimensional array, 2) the size of the column, and 3) a particular row number of the multidimensional array to be used for printing out the "pass" shown on the following pages.
I keep getting an error that the identifier for bubbleSort and selectionSort is not found. (Error C3861) Also, I feel like I'm missing something in int main() to get it to sort properly.
# include <iostream> using namespace std; int main() {
So I have an insertion sort function implemented that sorts through an array, but I'm having a problem showing the correct number of comparisons to work.
Each time I'm checking a value with another, the counter should update.
For instance, having an array of 10 elements going from 10-1 should give 45 comparisons, but I'm getting 54 comparisons.
void insertionSort(int a[], int& comparisons, const int& numOfElements) { int j, value; for (int i = 1; i < numOfElements; i++) { value = a[i]; for (j = i - 1; j >= 0 && a[j] > value; j--)
So i'm trying to implement the selection sort algorithm and it seems that the code is fine but...
Code: #include <cs50.h> #include "helpers.h" void sort(int values[], int n) { // TODO: implement an O(n^2) sort
[Code] ....
I keep getting these errors and i don't understand why:
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: ld returned 1 exit status
I'm trying to code a Singly-Linked List(Double Pointers) selection sort program and I can't tell what the problem is. My compiler says no errors but when I run the program, it crashes right after I enter the values.
I am trying to write a program to sort the characters in a word alphabetically. For example, if you input 'what', the computer will sort it into 'ahtw'. But, it fails to work. I didn't know why.
I have written a selection sort algorithm to go sort an array of class objects by age in ascending order, the problem is that the output being given does not match what i think the code should do. when the program runs the 3 records are added to the array and when they are sorted should be outputed in ascending order, the problem is that with my code the last 2 are sorted properly but the first element does not seem to move, it remains the same as the original unsorted value.
My code for the selection sort function and the display method are below:
void selectionSort() { int i, minIndex, minValue; for (i = 0; i < (arrlength - 1); i++) { minIndex = i ;
Question: What is the efficiency and big O of the selection sort algorithm when the input happens to already be in nondecreasing order?
Answer: Not sure... since the input is in nondecreasing order, such that example 0, 1, 1, 2, 3, 4, 4, 5 then there will be no swap, Just comparisons of emelemts. So it is big O of n
This program using the selection, insertion, and bubble sorts. The program needs to be able to do the following:
1. Create an array of 1000 population records when the array object is instantiated. Call it unSorted.
2.Open the file called "Population.csv" (on the portal) and invoke a function that loads the population data into the array.
3.Create a second array of 1000 elements that will be used to sort the data using the different algorithms. Name is sortedArray.
4.Write a function that will copy unSorted into sortedArray and execute that function.
5.Using a function, display the unsorted array.
6.Invoke the insertionSort () function that will sort the sortedArray using the insertion sort algorithm. Sort the population data on the rank field in ascending order. Alternatively, you can sort in descending order on population.
7.Using the display function, display sortedArray.
8.Display the number of iterations it took to do the sort using this algorithm.
9.Repeat steps 4-8 for the selection and bubble sort algorithms.
Here is my code so far:
Code: #include <iostream> #include <iomanip> #include <fstream> using namespace std; void loadArray (int unSorted[], int s); void displayArray (const int num [], int size);
[Code] .....
Here is a few lines from the Population.csv file contents:
I'm not sure how to load the data from the file into the array properly, I attempted this. I also don't know how to copy the unSorted into sortedArray.
I've written code for a selection sort algorithm to sort through a singly linked list, However, it only brings the smallest node to the front, but doesnt swap positions of any of the remaining nodes, even though they are not in order.

Code: # include <iostream> using namespace std; int main() { const int SIZE1 = 3; const int SIZE2 = 8; int arr [SIZE1][SIZE2] = { { 105, 102, 107, 103, 106, 100, 104, 101 },
I have a program that needs to calculate the total for three stores payrolls.
Inputs would be the three stores payrolls Output would be the total of all three
I HAVE to use the while statement.
I have also read the articles on the while statement on here and on other sites. I'm having trouble because every site I've seen so far has only been giving examples of numbers(like counting down or repeating a statement so many times).
Code:
#include <iostream> #include <cmath> using namespace std; int main() { //declare variables int storePayroll = 0; int totalPayroll = 0; int storeNum = 0;
I have a window form with datagridview,textbox,button and listbox. In datagridview i have added a column. In first row i have given the value like 7000,
second row 2500, third row 7000, fourth row 1000, fifth 1300, sixth 9000....n number of row:
if i enter 12000 in textbox1 then it will calculate the total in particular rows in datagridview.And the total should be less than 12000 what we have entered the value in textbox1.
The result will display in listbox..
like first greater value is 9000+2500=11500 , second greater value 7000+1000+1300=9500, other third greater value is 7,000.
So i have given a sample code where i cannot get the solution ..
double search; search = double.Parse(textBox1.Text); double sum = 0; for (int i = 0; i < dataGridView1.Rows.Count - 1; i++) { double se2 = Convert.ToDouble(dataGridView1.Rows[i].Cells[0].Value.ToString()); if (se2 == search) {
I want to calculate the total some of delay pf receiving Side Packet . Code is as Follow ..
What is weird that even if i invoke a sleep of 2 sec ,than its show delay always zero. Delay will be in microsec ..Is there any problem with logic or anything else..
Code:
do {#pragma omp parallel private(nthreads, tid) { /* Obtain thread number */ tid = omp_get_thread_num(); if (tid == 0) { nthreads = omp_get_num_threads();
Write a program which is used to calculate GPA based on the grades from different courses Input by the user. User should be able to enter as many course unless they choose to quit. Once the user has completed entering the data, the program should be able to provide a feedback on the GPA. Where A=4, B=3, C=2, D=1.
Write a program that calculates the total grade for N classroom exercises as a percentage. The user to input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total point possible) and output it as a percentage. Sample input and output it as a percentage. Sample input and output is shown below.
How many exercises to input? score1: 10 total points possible: 10 score2: 7 total points possible: 12 score3: 5 total points possible: 8
Code: # include <iostream> using namespace std; int main () { double N=0, score, total, totalScore=0, totalGrade=0, GRADE; cout<<"How many excersices will be scored?/n";
Write a C++ program to calculate the fewest number of each denomination needed to pay a bill of amount TOTAL. For example, if the end user enters $97 for TOTAL, program will output that the bills would consist of one $50 bill, two $20 bills, one $5 bill, and two $1 bills. (Assume that the amount is in whole dollars, no cents, and only $100, $50, $20, $10, $5, and $1 denominations are available.) Aid: You may want to use the modulus operator %.
I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:
You have 40 letters at $3.45 per letter, and your total is $138.00.
Everything compiles fine but when I run it the inputs don't work and it outputs:
You have -1 per letter, and your total cost is $-0.
SYNOPSIS : KBJ tourist agency Sdn. Bhd wants you to write an application program to calculate the total price for their customers for a package of vacation. The following table shows the price for three destinations (transportation and accommodation) offered by the agency:
Destination TransportationAccommodation Pulau Redang Child RM15.00 Adult RM30.00RM95 per day Pulau Perhentian Child RM20.00 Adult RM30.00 RM100 per day Pulau Kapas Child RM10.00 Adult RM20.00 RM120 per day
This agency company will give some discount to a group of customers with is:
a.10% discount will be given for the group that has a least 5 adults.
b.25% discount will be given for the group that has more than 5 persons (adults and children)
c.30% discount will be given for the group that has at least 15 persons.
Your application program has to display the output using this following screen layout:
KBJ TOURIST CUSTOMER INFORMATION
Customer’s name: XXXXXXXXXXXXX Number of Children:XXXXX Number of Adult: XXXXX Transportation: RMXXX.XX Accommodation: RMXXX.XX Total price: RMXXXX.XX
This is the code i got so far but it doesn't work..:(
#include <iostream.h> int main () { char customerName,code,A,B,C; int childNum,adultNum; double rate,discount,totalPrice,a,c;
Im just wondering how would i get a formula to calculate the total size and proportion of how far the media player has been played, in proportion with the size of the sizeable form, i need an int for the:
Width of formLength of movieHow long has been played by user
I have this code so far:
//The current position played! - Within the timer.tick event arg! string splayed = axWindowsMediaPlayer1.Ctlcontrols.currentPosition.ToString().Split('.')[0]; int iplayed = Convert.ToInt32(splayed + 1); //The total time of the movie/audio. string stotal = axWindowsMediaPlayer1.Ctlcontrols.currentItem.duration.ToString().Split('.')[0]; int itotal = Convert.ToInt32(splayed);
[Code] ....
I have the "AxWindowsMediaPlayer" reference installed, but i need to know how it would work...
The point of this is to calculate the total of the monthly costs of these 6 expenses and then to show the annual cost. However, there's just a couple of things that's giving me problems and it's the calcMonCost in my code. The error says that it is more than one instance of overload function and also that an unresolved external symbol. Everything else is fine. What does this mean?
I'm trying to make a selection process using roulette wheel selection. To do this I created two matrix, one random probabilities and one increasing probabilities. The idea is to choose a number according to the random probabilities. Here is the code I've written.
#include <iostream> #include <conio.h> #include <cstdlib> using namespace std; int main (){ float select [5], prob [10], mat [5]; int c, r, z; cout.precision (2); cout << "Random Number:" << endl;
[Code]...
The result I got is as follows:
Random Number:
0.0013 0.56 0.19 0.81 0.59
Increasing Probabilities:
0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1
Selected Column: 0 5 6 8 9
The evaluation doesnt seem to start from c=0 again. The selected column should be 0, 5, 1, 8, 5.
