# C++ Program Calculate the Sum, Average and standard Deviation of these Numbers.

**Object:** Write a C++ program by using pointer that receives array of 5 integers from keyboard and calculate the sum, average and standard deviation of these numbers. C++ projects for beginners with source code

## Code:

**#include<iostream>**

**#include<conio.h>**

**#include<math.h>**

**using namespace std;**

**void main()**

**{**

** int num[5],i,sum=0,avg,stdvi,var=0;**

** int *p[5];**

** cout<<“Enter 5 Numbbers:\n”;**

** for(i=0;i<5;i++)**

** {**

** cin>>num[i];**

** p[i]=&num[i];**

** sum+=*p[i];**

** }**

** avg=sum/5;**

** for(i=0;i<5;i++)**

** {**

** var+=pow(num[i]-avg,2);**

** var=var/5;**

** stdvi=sqrt(var);**

** }**

** cout<<“Sum of 5 Numbers is: “<<sum;**

** cout<<“\nAverage of 5 Numbers is: “<<avg;**

** cout<<“\nStandard deviation of these Numbers is: “<<stdvi;**

** getch();**

**}**

Valuable information. Lucky me I found your website by accident, and I’m shocked why this accident didn’t happened earlier! I bookmarked it.
