# Find Frequency of Odd & Even Numbers

Write a C Program to Find Frequency of Odd and Even Numbers in Matrix. Here’s simple Program to Find Frequency of Odd and Even Numbers in 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 Frequency of Odd and Even Numbers in Matrix which is successfully compiled and run on Windows System to produce desired output as shown below :

### SOURCE CODE : :

```/*  C Program to Find Frequency of Odd and Even Numbers in Matrix  */

#include <stdio.h>

int main()
{
static int array[10][10];
int i, j, m, n, even = 0, odd = 0;

printf("Enter no. of rows :: ");
scanf("%d", &m);
printf("\nEnter no. of cols :: ");
scanf("%d",&n);
printf("\nEnter values to the matrix :: \n");
for (i = 0; i < m; i++)
{
for (j = 0; j < n; j++)
{
printf("\nEnter a[%d][%d] value :: ",i,j);
scanf("%d", &array[i][j]);
if ((array[i][j] % 2) == 0)
{
++even;
}
else
++odd;
}
}
printf("\nThe given matrix is \n\n");
for (i = 0; i < m; ++i)
{
for (j = 0; j < n; ++j)
{
printf("\t%d", array[i][j]);
}
printf("\n\n");
}
printf("\nThe frequency of occurrence of odd number  = %d \n", odd);
printf("\nThe frequency of occurrence of even number = %d\n", even);

return 0;

}```

### OUTPUT : :

```/*  C Program to Find Frequency of Odd and Even Numbers in Matrix  */

Enter no. of rows :: 3

Enter no. of cols :: 3

Enter values to the matrix ::

Enter a[0][0] value :: 1

Enter a[0][1] value :: 2

Enter a[0][2] value :: 3

Enter a[1][0] value :: 4

Enter a[1][1] value :: 5

Enter a[1][2] value :: 6

Enter a[2][0] value :: 7

Enter a[2][1] value :: 8

Enter a[2][2] value :: 9

The given matrix is

1       2       3

4       5       6

7       8       9

The frequency of occurrence of odd number  = 5

The frequency of occurrence of even number = 4

Process returned 0```

Above is the source code for C Program to Find Frequency of Odd and Even Numbers in Matrix which is successfully compiled and run on Windows System.The Output of the program is shown above .
