Need help with Programming statistics

[abba901]

Not sure how to start on the homework assignment.
Assignment:
Write a C++ program that accepts 5 integers from a user and then calculates their arithmetic mean, geometric mean, harmonic mean, and standard deviation (all statistics must be stored in doubles). The program should then print and label the original 5 numbers and the four statistics. You will need to include the math library (#include <cmath>) to use pow() and sqrt().

Your program must implement the following equations:
Arithmetic Mean
Geometric Mean
Harmonic Mean
Standard Deviation




Any help would be greatly appreciated.
Thank you.

I'd start by writing out the 5 equations you need in pseudo-code:

AM = (a + b + c + d + e) / 5
GM = (abcde) ^ (1/5)
HM =  1 / ((1/a + 1/b + 1/c + 1/d + 1/e) / 5)
SD = sqrt(((a - AM)^2 + (b - AM)^2 + (c - AM)^2 + (d - AM)^2 + (e - AM)^2) / 5)

The rest should just be basic I/O.

#include <iostream>
#include <cmath>

using namespace std;

int main()
{
    AM = (a+b+c+d+e)/ 5.0
    GM = (abcde)^(1.0/5.0)
    HM = 1.0 / (1.0/a + 1.0/b + 1.0/c + 1.0/d + 1.0/e) / 5.0)
    SD = sqrt(((a-AM)^2.0 + (b - AM)^2.0 + (c - AM)^2.0 + (d - AM)^2.0 + (e - AM)^2.0) / 5.0)


    cout <<  << endl;
    return 0;
}

I'm still stuck on what else to write out.

how about asking the user for 5 integers ?

Thanks.

include <cmath>
include <iostream>
using namespace std;
int main()
{
int a, b, c, d, e;
cout << " Enter the first integer ";
cin >> first integer;
cout << " Enter the second integer ";
cin >> second integer;
cout << " Enter the third integer ";
cin >> third integer;
cout << " Enter the fourth integer ";
cin >> fourth integer;
cout << " Enter the fifth integer ";
cin >> fifth integer;
cin >> a >> b >> c >> d >> e;
cout <<
}

{
arithMean = calc(a+b+c+d+e) / 5.0
return ArithMean;
geoMean = pow(abcde)^(1/5)
return geoMean;
harmoMean = calc 1.0 / (1.0/a + 1.0/b + 1.0/c + 1.0/d + 1.0/e) / 5.0)
return harmoMean;
standdev = sqrt(((a - AM)^2.0 + (b - AM)^2.0 + (c - AM)^2.0 + (d - AM)^2.0 + (e - AM)^2.0) / 5.0

Still having troubles linking them together and am I missing anything important? How would I do a summation?

Thanks.
