C :: Bubble Sorting Failed - Prints A Blank Record
Feb 19, 2014
Well still working on my project, now the bubble sorting failed. For some reason the first slot in the array is empty and when I attempt to enter a record to access, it just crashes or prints a blank record. Here is my code for the viewing of the record and a SS of the empty array slot.
Code:
void searchRec(void) {
void Printing(int *ver, int *max);
FILE *fPtr;
struct Students vStudnt;
int set;
int ver;
int i = 0;
int fin = 0;
int sel;
char order;
[Code]...
Well I don't see why there is a empty slot, why?

So here I have a program that is supposed to basically sort out who passed and failed. I am currently stuck on the switch statement, I'm trying to count how many students received an A, B, C, etc.
Here's what I have so far:
#include <iostream>
#include <fstream>
#include <iomanip>
using namespace std;
void printIdInfo(ofstream &fout);
void printColumnHeaders(ofstream &fout);

I have to read data from a text file, load it into an array and then bubble sort it! Here is my code:
Code:
#include <iostream>
#include <string>
#include <fstream>
[Code]....
Basically what i am trying to do is that sort the names of 10,000 movies and then write those names to a text file. It gives an error in the nested loop by underlining arr and tells that no suitable conversion function from std::string to const char* exists.

I'll make a program that consists of "sorting and searching." To cope with the task, it should contain this: Create a field containing 50 random numbers, sort them by a method sort according to Bubble sort and then out the field before and after sorting. [URL]

I'm really struggling with bubble sorting a classed array(an inventory). I understand bubble sorting in theory and implementing it into a static array makes sense. When I get to doing it in a classed array then I struggle. I need to sort the weight by bubble sort (then selection sort for name, and insertion sort the cost; but I want to tackle one problem at a time.
Here is the code:
#include <iostream>
#include <iomanip>
#include <conio.h>
#include "Inventory.h"
#define MAX_REC 10
using namespace std;
//Class to hold inventory variables/funcitons

i wanted to sort an array with double bubble sort but it didnt work!
my code is this:
void doubleBubbleSort(int *array, int length) {
int i,j;
for(i=0; i<length--;i++) {
if(array[i]>array[i++])
for(j=i;j>=0&&(array[j]>array[j++]);j--)
std::swap(i,j);
[code].....
how to get time like 1.56 seconds,too!

I'd like to modify this code so that there is 1000 numbers instead of 100, and that they're sorted in ascending order instead of descending order.
#include <iostream>
#include <cstdlib>
#include <ctime>

double* sort_array(double* sort) {
for (int a=1; a<100; a++) {

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:
Code:
Alabama,Baldwin County,140415,389
Alabama,Blount County,51024,908
Alabama,Calhoun County,112249,477
Alabama,Colbert County,54984,858
Alabama,Cullman County,77483,653
Alabama,Dale County,49129,927
Alabama,Dallas County,46365,974
Alabama,DeKalb County,64452,753
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 am writing some code to bubble sort a list of randoms numbers, 10 at the moment. I want to be able to user input the amount of elements that would be sorted. I think i'd have to use vector instead of arrays, but unsure how to do this. Or, how to be able to change the size of the array.
#include <iostream>
using namespace std;
#define SIZE 10
float numbers[SIZE];
int move_n;

This program is sorting a randomized array of integers using the bubblesort algorithm.
I am trying to modify n correct the source code,so that the swapping of two values will be done by a function called swap values() by using call-by-reference but function should have as arguments only the two array elements that must be exchanged. (Note: do not pass the whole array to the function!) .We consider an array with the first element containing the number of elements in the array, followed by 10 randomly initialized integers (elements).
The code must sort the 10 elements in ascending order.
Compile: g++ -Wall sorting.cpp -o sorting
*/
#include <iostream>
#include <stdlib.h>
using namespace std;
int main() {
const int SIZE=10;

I have a code able to import a file containing words and numbers to a linked list, but I also need to sort this linked list alphabetically. I've done research on this involving bubble sorting, but no explanationcan achieve this objective.
Below is the code that can only put the file into linked list:
Code:

This compiles fine but when I run the .exe for the first time an error message comes up saying program has stopped working. If I run the program again without recompiling it seems to work as expected.

I'm doing a project where I have to store information gathered (temperature and the time it was taken in seconds) in two separate vectors. After an unknown amount of data has been entered, and the end-of-file has been reached, I have to display the highest temperature and the time(s) it occured (bear in mind that the highest temperature may be recorded more than once). The output of that part should be as follows:
Highest temperature: 51
Recorded at time(s):
22:45
2:27
Something like that. The time should also be converted to hours and minutes. To the point: I've done some research on bubble sorting, but they only use it for arrays.

I'm trying to make a c++ program of this but i don't know how to use the bubble sorting.
Write a C++ application that asks the user to enter 10 numbers. The program then stores those numbers in an Array. The program should display the Mean , Median, and Mode.
Mean is the average of the 10 numbers.
Median is the average of the 5th and the 6th numbers. (But you have to arrange the numbers in ascending order first using Bubble Sort before calculating the Median.)
Mode is the most frequent number among the 10 numbers.

I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
3 quarters
2 dimes
0 nickles
3 pennies
but instead it prints
3 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
Why it's doing this?
Code:
#include <iostream>
using namespace std;
int coinscount(int& amount, int value) {
int tracker = 0;
int amountdimes = amount;
