C++ :: Pointers (Average And Median)
Apr 29, 2014Write a program that can be used to gather statistical data about the number of movies college students see in a month. The program should ask the user how many students were surveyed and dynamically allocate an array of that size. The program should then allow the user to enter the number of movies each student has seen. The program should then calculate the average, and median of the values entered.
My problem is that i keep getting a error box that says:
Run-Time Check Failure #2 - Stack around the variable 'sNUM' was corrupted.
and then my program shuts down!
This is what i have so far
Code:
#include <iostream>
#include <iomanip>
using namespace std;
void movAVG(int *, int);
void movMED(int *, int);
int main() {
int sNUM,
sARRAY,
*sARRAYptr;

C++ :: Generate A List Of 200 Random Numbers - Determine Median / Mode And Average
Oct 24, 2013I 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.
C++ :: Dynamic Arrays - Sort Input Data And Calculate Average
Jul 15, 2014I'm still fairly new to c++ and am having trouble with dynamic arrays. My task is to create an array for test scores. The user needs to define the size of the array and then input data to later sort and calculate the average.
Below is what I have so far. I am struggling with the user input part. I receive the following errors for the data input of the individual scores:
"error C2108:subscript is not of integral type"
"IntelliSense:expression must have integral or unscoped enum type"
Code :
#include<iostream>
#include<iomanip>
using namespace std;
int main() {
//user input total number of scores
cout<<"Please enter the total number of test scores."<<endl<<endl;

C++ :: Pointers And Arrays - Program To Display Sorted List And Average Of Scores With Appropriate Headings
Apr 22, 2014I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.

Nov 14, 2013I must write a function that has a one dimensional double array and the number of values in the array as its arguments. Normalize the values. I must also print the maximum, minimum, average and numbers of values above the average in the array.

C++ :: Average Negative / Positive Numbers And Total Average?
Nov 18, 2013I am trying to average the negative numbers and positive number and of course the total average.
This will read in a list of n values, where n is not known ahead of time. The number of values read into the array will be saved in n.

std::vector<int> result;
ifstream inFile;
inFile.open("setA.txt");

array is a one-dimensional array of integers and n is the number of elements in that array that contain valid data values. Both of these are input parameters to the function. The function must calculate 1) the average of the n integers in array, storing the result in ave; 2) the average of the positive numbers (> 0), storing the result in avePos, and 3) the average of the negative numbers (< 0), storing the result in aveNeg.
void avgs (std::vector &array, int &ave, int &avePos, int &aveNeg) {
int sum = 0, pos_sum = 0, neg_sum = 0, pos_count = 0, neg_count = 0;

C++ :: Sorting And Calculating Median Of A Vector?
Dec 1, 2014I 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()

C/C++ :: Two Dimensional Array Median Filtering?
Nov 12, 2014I'm trying to write code that implements [median filtering] on a two-dimensional array.
Here's an image to illustrate:
The program starts at the beginning of the array. The maximum array size is 100. I know that I can use an array like:
int a[100][100];
to store the input, and that I can iterate over a part of this array using two `for` loops like this:
for(i=0;i<size_filter;i++)
for(j=0;j<size_filter;j++)
temp[i][j]=a[i][j] // not so sure
But how can I make this code loop over the neighbors of every element in the array, calculate their median, and replace the center element with the median?
For some examples of what I'm trying to do, let's say that the input is a 5x5 matrix, so the input size is 5. And I want to run a 3x3 median filter on it, i.e. each element should be replaced by the median of the 3x3 elements surrounding it.
The program starts at the corner index (0,0). For this index, it scans the 3x3 region surrounding it (of which only four indexes actually lie within the input array), which contains the values 0, 0, 1, and 0. The median of these values is 0, so that's what the code should output for this array index.
In the picture below, the number in -band - is the center cell, and the plain * and * numbers are its neighbors within the 3x3 region surrounding it:
-0- *0* 0 0 0
*1* *0* 0 1 0
1 1 0 0 0
0 1 1 0 0
0 0 0 0 0
Here's another example, this time with the center index (0,1):
*0* -0- *0* 0 0
*1* *0* *0* 1 0
1 1 0 0 0
0 1 1 0 0
0 0 0 0 0
This time, the elements in the 3x3 region (excluding those outside the input array) have the values 0, 0, 0, 1, 0, and 0, and again, their median is therefore 0.
Here's yet another example, this time from the middle of the input, at center index (3,2):
0 0 0 0 0
*1* *0* *0* 1 0
*1* -1- *0* 0 0
*0* *1* *1* 0 0
0 0 0 0 0
This time, the elements within the 3x3 region have the values 1, 0, 0, 1, 1, 0, 0, 1, and 1, and their median in therefore 1.
Final example:
<size of array><size filter> <data>
8
3
0 0 0 0 0 0 0 0
0 5 0 0 6 0 0 0
0 0 0 0 0 7 0 0
0 0 0 0 5 0 0 0
0 0 0 5 6 0 0 0
0 0 8 5 5 0 0 0
0 0 0 7 0 0 9 0
0 0 0 0 0 0 0 0
Output:
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 5 5 0 0 0
0 0 0 5 5 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
C++ :: Calculate Mode / Mean And Median Of Array Of Integers
Mar 17, 2013I'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.
C/C++ :: Find Minimum - Getting Median And Mode In Array
Feb 7, 2015So 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() {

C/C++ :: Calculating Median And Mode In Movie Statistics Program
May 5, 2014I 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 <iomanip>
using namespace std;
// Function prototypes
double calculateMean(int *, int);
double calculateMedian(int *, int);
int calculateMode(int *, int);

C++ :: Store User Input In Array And Calculate Mean / Median And Mode - Bubble Sorting
Mar 26, 2014I'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.

C++ :: Using Arrays As Sources Of Data For Arrays In A Structure?
Feb 6, 2014I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)

C :: Assigning Values To Arrays / Printing Arrays
Jul 1, 2014Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?

C++ :: Ranged For Loop With Arrays Of Arrays
Dec 17, 2014int arr[4][5];
for (int(&row)[5] : arr){
for (int &column : row){
} }
Why do we name it row instead column?
int arr[row][column]
Wouldn't this be like
int arr[4][5];
for (int(&column)[5] : arr){
for (int &row: column){
}
It just seems funny to me because we use row[5] which should be 4 if we meant row? Or did I read it wrong in C++ prime !?
