Average of list of numbers by C++ Programme

Average of a set numbers by C++ Programme

AIM:

To find average of a given set of numbers by using C++ Programme.

REQUISITES:

A PC or laptop, Turbo C++ compiler installed in it.

THEORY:

For a data set, the terms arithmetic mean, mathematical expectation, and sometimes average are used synonymously to refer to a central value of a discrete set of numbers.

If x1,x2,x3…….xn are a set of data, the mean can be calculated as

Xmean=Average=(x1+x2+………….+xn)/n

CODING:

#include<iostream.h>

#include<conio.h>

void main()

{

int a[100],sum=0,n,avg,i;

clrscr();

cout<<"Enter a number :";

cin>>n;

cout<<"Enter " ""<<n<<" ""numbers :"<<endl;

for (i=0;i<n;i++)

{

cin>>a[i];

}

for (i=0;i<n;i++)

{

sum=sum+a[i];

}

avg=sum/n;

cout<<"The average is:"<<avg;

getch();

}
