C Program to check whether a given matrix is symmetric or not

C Program to check whether a given matrix is symmetric or not 

A matrix is symmetric if its transpose is same as the matrix itself check the martix by using C Logic.

//write matrix

{
int i,j;
{
for(i=0;i<n;i++)
for(j=0;j<n;j++)

for(i=0;i<n;i++)
for(j=0;j<n;j++)
scanf("%d",&a[i][j]);
}

//main function

//accept matrix
printf("Enter size of square matrix");
scanf("%d",&n);
read_mat(a,n);

//check if the matrix is symmetric or not
