# Largest and Smallest Element of a Matrix

Write a C++ Program to Find Largest and Smallest Element of a Matrix. Here’s simple Program to Find Largest and Smallest Element of a Matrix in C++ Programming Language.

## What is Matrix ?

Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory. C uses “Row Major”, which stores all the elements for a given row contiguously in memory.

Two-dimensional Arrays : :

The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. An m × n (read as m by n) order matrix is a set of numbers arranged in m rows and n columns.

To declare a two-dimensional integer array of size [x][y], you would write something as follows −

• type arrayName [ x ][ y ];

Where type can be any valid C data type and arrayName will be a valid C identifier.

Below is the source code for C++ Program to Find Largest and Smallest Element of a Matrix which is successfully compiled and run on Windows System to produce desired output as shown below :

### SOURCE CODE : :

```/*  C++ Program to Find Largest and Smallest Element of a Matrix */

#include<iostream>

using namespace std;

int main()
{
int m,n,a,i,j,high,low;
cout<<"Enter no. of rows :: ";
cin>>m;
cout<<"\nEnter no. of coloumns :: ";
cin>>n;
cout<<"\nEnter Elements to Matrix Below :: \n";

for(i=0;i<m;i++)
{
for(j=0;j<n;++j)
{
cout<<"\nEnter a["<<i<<"]["<<j<<"] Element :: ";
cin>>a[i][j];
}

}

cout<<"\nThe given matrix is :: \n\n";
for (i = 0; i < m; ++i)
{
for (j = 0; j < n; ++j)
{
cout<<"\t"<<a[i][j];
}
printf("\n\n");
}

high=a;
low=a;

for(i=0;i<m;++i)
{
for(j=0;j<n;++j)
{
if(a[i][j]>high)
high=a[i][j];
else
if(a[i][j]<low)
low=a[i][j];
}
}

cout<<"\nHighest Element :: "<<high<<"\n\nLowest Element :: "<<low<<"\n";

return 0;
}```

### OUTPUT : :

```/*  C++ Program to Find Largest and Smallest Element of a Matrix */

Enter no. of rows :: 3

Enter no. of coloumns :: 3

Enter Elements to Matrix Below ::

Enter a Element :: 1

Enter a Element :: 2

Enter a Element :: 3

Enter a Element :: 4

Enter a Element :: 5

Enter a Element :: 6

Enter a Element :: 7

Enter a Element :: 8

Enter a Element :: 9

The given matrix is ::

1       2       3

4       5       6

7       8       9

Highest Element :: 9

Lowest Element :: 1

Process returned 0```

Above is the source code for C++ Program to Find Largest and Smallest Element of a Matrix which is successfully compiled and run on Windows System.The Output of the program is shown above .
