C++ :: Generate A List Of 200 Random Numbers - Determine Median / Mode And Average
Oct 24, 2013
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 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 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 trying to generate random numbers so that I can assign people to teams. So far I have come up with this
Code:
int generateTeam(){
int i, teamNumber, c, n;
for (c = 0; c <= 5; c++) {
n = rand()%100 + 1;
}
[code]....
}//end generateTeam I'm not sure how to make it so that I can exclude the previous random number when generating the next one. As an example, I have 22 students and I get the number 19. Now I can't have 19 again because that guy already has it.

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;

The program is to generate random numbers to a file and will have one integer parameter, Open a file and then using a loop write the required number of random numbers to the file. Scale the random numbers from 1 and 100 inclusive. Then closes the file .The last function will read the numbers in the file into your program. so far i have
Code: #include <iostream>
#include <string>
#include <iomanip>
#include <ctime>
#include <fstream>
#include <cstdlib>

srand (time(NULL));
for(int i=0; i<N; i++) {
points[i].x=(rand()%(32767-(-32767)))+(-32767);
points[i].y=(rand()%(32767-(-32767)))+(-32767);
cout<<"x="<<points[i].x<<endl;
cout<<"y="<<points[i].y<<endl;
}
Im trying to generate random numbers between -32767 and +32767, where im going wrong, this code generates only negative numbers

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);

I have the random values down but when I try to assign randValue to another integer I get an error.I want to make an inner loop where I find 5 random number 50 times and print the average of those numbers.
I know I have the bare bones of the below, but without giving me a huge shove in the right direction can I have a poke? I have been programing for three months now. I have noticed when I do simple fun projects I learn more then what my professor assigned to me. The class is over but I want to keep building.C++ starts in one week...
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NUMBERS 5
int main(int argc, const char * argv[]) {
float randValue = 0.0;
int i;

So, there has got to be an easier way to generate random numbers within a specific range. Here is the code that I have been using, for a range of 1-6:
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

My program generates an array of random numbers. I want to then search a specific number within the array. If the number is in the array then a message apopears on the console saying that its there. I'm using the binary search algorithm to do this.
#include <iostream>
#include <ctime>
#include <cstdlib>
#include <iomanip>
#include <cstring>
using namespace std;
int size;
int getSize() { return size; }

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.

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,

I 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.
vector<int> readList() {
std::vector<int> result;
ifstream inFile;
inFile.open("setA.txt");
for (int x; inFile >> x; ) {
result.push_back(x);
[code]....
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;
for (auto i : array) {
sum += i;
if (i > 0) { pos_sum += i; ++pos_count; }

I need my program to read a list of numbers from and input file, random.txt, and calculate the following statistics on those numbers:
A. The number of numbers in the file.
B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>

I'm trying to write a program that generates a random number between 50 and 200. I made a program that generates random numbers, but how to make those random numbers be in-between 50 and 200. Any example of a program that generates random numbers that are confined in-between certain values?

I just can't seem to get this right. What I want to happen is when the program runs a random word should pop up.
I have included my code. I'm not sure by putting tag around my code.
