--Originally published at TC1017 Programing Curse

This time i have to create a program that asks the user for 10 numbers, and store those numbers in a list. Show to the user the total, average and standard deviation of those numbers.

Also we can see mastery topic 18 here, the use of list, http://www.cplusplus.com/doc/tutorial/arrays/ this page helped me.

#include <iostream>
#include <math.h>
using std::cout;
using std::cin;
using std::endl;

float getTotal(float numbers[], int numNumbers){
float answer=0.0;
for(int i = 0; i < numNumbers; i++){
answer = answer + numbers[i];
}
return answer;
}

float getAverage(float numbers[], int numNumbers){
float answer=0.0;
answer = getTotal(numbers,numNumbers);
answer = answer / numNumbers;
return answer;
}
float getStdDev(float numbers[], int numNumbers){
float varianza=0.0, answer=0.0, prom=0.0, dev=0.0;
prom = getAverage(numbers,numNumbers);
for(int i = 0; i < numNumbers; i++){
varianza = varianza + pow((numbers[i]-prom),2);
}
dev = sqrt(varianza/numNumbers);
return dev;
}
int main(){
const int NUM_NUMBERS=10;
float x[NUM_NUMBERS];
for (int i = 0; i < NUM_NUMBERS; i++){
cout << “Dame un número “;
cin >> x[i];
}
float total = getTotal(x,10);
float average = getAverage(x,10);
float stdev = getStdDev(x,10);
cout << “El total es: ” << total << endl;
cout << “El promedio es: ” << average << endl;
cout << “La desviación estándar es: ” << stdev << endl;
}
