C++ :: Store User Input In Array And Calculate Mean / Median And Mode - Bubble Sorting
Mar 26, 2014
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'm writing a program that calculates the mode, mean and median of an array of integers. I've done the mean and median but i can't figure out mode.
I have to find the number of modes.
Ex array of integers: 10, 10, 4, 5, 6,5, 6, 7
My function has to return the number 3. Because there are 3 sets of mode; 10,5,6.
How do i implement this in my function because for now it just calculates the mode. It only return the number mode 10.

So I am trying to find the min, max, range, mean, median, and mode. The max number is right but the min isnt. Once that is corrected, i can get range and mean easily. Also, how to get mode and median. I am guessing the values in the arr2 would have to be sorted. This refers to the values in arr2 which are the calculated values in the formula. You can enter -2 and 2 for userMin and userMax.
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
cout << fixed << setprecision(1);
float userMin;

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;

I am making program that allows the user to determine how big the array size will be and then asks the user to make up numbers to fill the array. Every time run the program on Dev C++ it says "program has stopped working"
Heres My Code:
//Assignment 19 Program 2
#include <iostream>
using namespace std;
int main()

Were supposed to be able to sort an array which is user input, but the first number they input is supposed to be the length of the array, and everything after that is the actual array.
Here is my code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int size;
int list[80];
bool isSorted (const int list[], int size);
[code]....
I'm stuck on how I'm supposed to use the first digit of input for the array size.

I have been reading up on arrays and string array. I created a string string text[0] and it is defined by user input. I am trying to sort the input. I want Michael to read Macehil.
When I wasn't using an array and just a string I did this:
return sort(text.begin(), text.end()); a
And it worked fine. Do I need to change my string into a char? If so, would I static cast that?

I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {
[code]....
EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.

I am writing code, which reads an input file (280 MB) containing a list of words. I would like to compute
1) total # of words
2) total # of unique/distinct words
3) mean/median/mode of word count (Link)
I managed to get done with 1) and 2), but my program crashes for 3). I am not quite sure whether there are memory issues or some bug in the code.
Code:
#include <iostream>
#include <fstream>
#include <string>
#include <map>
using namespace std;

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);

how to get time like 1.56 seconds,too!

I needed to compute average median and mode for numbers in a vector. Im having a few issues I have already figured out how to calculate average and median just not mode. Also the program crashes when 0 is entered instead of exiting nicely. Also i keep getting a error on line 47 saying primary expression expected before else.
#include <iostream>
#include <conio.h>
#include <math.h>

I am having trouble calculating the median and mode in a program that I am writing. When I run the program, lets say there are 5 students being surveyed. The input is as follows, Student #1 sees 2 movies, student #2 sees 6,student #3 sees 5 movies, student #4 sees 2 movies, and student #5 sees 1 movie. However, for the median, I get 5, because that is at element 2, and thus midway through the count, so the program interprets that number as the median. For the mode, even though 5 is repeated twice, the program displays that there was no mode, or displays "-1" (indicating no mode). Here is my code:
Write a program that can be used to gather statistical data about the number of movies college students see in a month. The program should perform the following steps:
A) Ask the user how many students were surveyed. An array of integers with this many elements then be dynamically allocated.
B)/> Allow the user to enter the number of movies each student saw into the array.
C) Calculate and display the average, median, and mode of the values entered.
Input Validation: Do not accept negative numbers for input.
#include <iostream>
#include <iomanip>
using namespace std;
// Function prototypes
double calculateMean(int *, int);
double calculateMedian(int *, int);
int calculateMode(int *, int);

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>

I am just starting out programming and have an assignment due in the near future. the problem is I cant seem to figure it out. I started it already but got stuck cant seem to figure it out. Here is the assignment.
Create a program that will generate a list of 200 random numbers (ranging from 1-1000) and determine the medium, mode, and average of the list of numbers. Have the program display the original list ant then display the list in ascending and descending order on the screen.

I am trying to to pull data from a file into a vector, then calculate different statistics from said vector. I've got everything working great except for one part. The program requires the median be calculated, which means I need to sort the data in the vector. However I can't do a quick easy sort, I'm required to use the functions swap(double, double), sort(vector), and index_of_smallest.
how to get these all working in sync to calculate the median(not to mention my algorithms appear to be wrong as I return nothing but 0's for the median value.)
I'm either not sorting right, or the index_of_smallest function is supposed to be doing something I don't realize.
#include <iostream> // for screen and kbd io
#include <iomanip>
#include <fstream> // file io
#include <cstdlib> // for exit()
#include <cmath> // for sqrt
#include <string>
#include <vector>
using namespace std;
void fill_vector(ifstream& in_file,vector<double>& v);

I can`t seem to store multiple values into my vector when a user keys in an input. Lets say a user inputs 1,2 as the first set and later keys in 3,4.
My vector gets overridden by 3 and 4. I'm trying to pass these values into a function to store them into a vector and use them in the function.
Below is my code snippet
int reconstructSecret(int x, int y) {
int getX,getY;
getX=x;
getY=y;
vector<int> myXCordVec;
vector<int> myYCordVec;

My program is designed to read input from the user and then store that input in a structure variable. Whenever i use the cin.getline() function, it comes up with a semantic issue. Here is the code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int DESCRIPTION_SIZE = 100, DATE_SIZE = 20;
struct inventory {
string description[DESCRIPTION_SIZE];
[Code] .....
I left out the other functions. The error reads "no matching member function for call to 'getline'.

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 am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () {
double accuracy;
cout<<"Give an accurate number." << flush;//looks nice
cin>>accuracy;
int d;//initialize denominator
double pi = 0.0;
while(accuracy < d){
