C Program to Check Symmetric Matrix

C program to check symmetric matrix; Through this tutorial, we will learn how to check symmetric matrix in c programs.

Algorithm to check symmetric matrix

Use the following algorithm to write a program to check symmetric matrix; as follows:

1. Start Program
2. Input elements in matrix A.
3. Find transpose of matrix A, store it in some variable say B.
4. Check if matrix A is equal to its transpose A^T then it is symmetric matrix otherwise not. Means check if A_ij = A^T_ij (Where 1 ≤ i ≤ m and 1 ≤ j ≤ n) then the matrix is symmetric.
5. Stop Program.

C Program to Check Symmetric Matrix

/* C Program to check Matrix is a Symmetric Matrix or Not */

#include<stdio.h>

int main()
{
 	int i, j, rows, columns, a[10][10], b[10][10], Count = 1;

 	printf("\n Please Enter Number of rows and columns  :  ");
 	scanf("%d %d", &i, &j);

 	printf("\n Please Enter the Matrix Elements \n");
 	for(rows = 0; rows < i; rows++)
  	{
   		for(columns = 0;columns < j;columns++)
    	{
      		scanf("%d", &a[rows][columns]);
    	}
  	}
   	//Transpose of matrix
 	for(rows = 0; rows < i; rows++)
  	{
   		for(columns = 0;columns < j; columns++)
    	{
      		b[columns][rows] = a[rows][columns];
    	}
  	}

 	for(rows = 0; rows < i; rows++)
  	{
   		for(columns = 0; columns < j; columns++)
    	{
    		if(a[rows][columns] != b[rows][columns])
    		{
    			Count++;
				break;
			}
   	 	}
  	}
  	if(Count == 1)
  	{
  		printf("\n The Matrix that you entered is a Symmetric Matrix ");
	}
	else
	{
		printf("\n The Matrix that you entered is Not a Symmetric Matrix ");
	}

 	return 0;
}

The output of the above c program; as follows:

Please Enter Number of rows and columns  :  3 3
Please Enter the Matrix Elements
1 2 3
2 4 5
3 5 8
The Matrix that you entered is a Symmetric Matrix
