Symmetric matrix in C

C program to check if a matrix is symmetric or not: we find the transpose of the matrix and then compare it with the original matrix. For a symmetric matrix A, AT = A.

C program to check if a matrix is symmetric or not

#include<stdio.h>

int main()
{
  int m, n, c, d, matrix[10][10], transpose[10][10];

  printf("Enter the number of rows and columns of matrix\n");
  scanf("%d%d", &m, &n);
  printf("Enter elements of the matrix\n");

  for (c = 0; c < m; c++)
    for (d = 0; d < n; d++)
      scanf("%d", &matrix[c][d]);

  for (c = 0; c < m; c++)
    for (d = 0; d < n; d++)
      transpose[d][c] = matrix[c][d];

  if (m == n) /* check if order is same */
  {
    for (c = 0; c < m; c++)
    {
      for (d = 0; d < m; d++)
      {
        if (matrix[c][d] != transpose[c][d])
          break;
      }
      if (d != m)
        break;
    }
    if (c == m)
      printf("The matrix is symmetric.\n");
    else
      printf("The matrix isn't symmetric.\n");
  }
  else
    printf("The matrix isn't symmetric.\n");

  return 0;
}
