PROGRAM TO DISPLAY THE ELEMENT OF 2-D ARRAY

DESCRIPTION-:This program display the elements of two dimensional array.means that it display elements of array in the form of matrix.
In this program we must specifies the number of rows and columns in the array.

PROGRAM-:
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int i,j,m,n,a[100][100];
cout<<"enter number of rows and column in array"<<"\n";
cin>>m>>n;
cout<<"enter value of elements of array"<<"\n";
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
cin>>a[i][j];
}
}
cout<<"values of 2-D array element is"<<"\n";
for(i=0;i<m;i++)

PROGRAM TO CALCULATE AVERAGE OF 'n' ELEMENTS USING ARRAY

DESCRIPTION-: This program calculate the average of all the elements of an input array.this program firstly calculate the sum of the elements of array and after calculating the sum it calculate the average of elements of array by dividing sum to the number of elements in an array.

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int i,n,sum=0,a[20];
float avg;
cout<<"enter number of elements in array";
cin>>n;
cout<<"enter value of elements of array"<<"\n";
for(i=0;i<n;i++)
{
cin>>a[i];
}
cout<<"sum of elements of array are"<<"\n";
for(i=0;i<n;i++)
{
sum=sum+a[i];
}
cout<<"sum ="<<sum<<"\n";
avg=sum/n;
cout<<"average ="<<avg;
