C Program to calculate the normal of a matrix

This is a C Program which calculates the normal of a given matrix.

Generally normal of a matrix is calculated as the root of sum of squares of all the elements in a matrix.

PROGRAM :

#include <stdio.h>
#include <stdlib.h>
#include<math.h>

int main()
{
    int sum=0,rows,columns,i,j;
    float normal;
    printf("Enter order of matrix : \t");
    scanf("%d%d",&rows,&columns);
    int matrix[rows][columns];   
    printf("Enter elements of the matrix \n");
    for(i=0;i<rows;i++)
    {
        for(j=0;j<columns;j++)
        {
            printf("Enter element m%d%d: \t",i+1,j+1);
            scanf("%d",&matrix[i][j]);
        }
    }
    printf("\n\nMATRIX is :\n");
    for(i=0;i<rows;i++)
    {
        for(j=0;j<columns;j++)
        printf("%d\t",matrix[i][j]);
        
        printf("\n");
    }
    printf("\n\nIts NORMAL is:\n");
    for(j=0;j<columns;j++)
    {
        for(i=0;i<rows;i++)
        sum  = sum +pow( matrix[i][j] , 2 );
        
    }
    normal = sqrt(sum);
    printf("%f\n",normal);
    return 0;
}

OUTPUT :

C -  Normal of a matrix
