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.




#include
#include

//write matrix
void write_mat(int a[][10],int n)
{
int i,j;
{
for(i=0;i<n;i++)
for(j=0;j<n;j++)
printf("%10d",a[i][j]);
printf("\n");
}
}

//read matrix
void read_mat(int a[][10],int n)
{
int i,j;
printf("Enter %d X %d matrix below:\n",n,n);
for(i=0;i<n;i++)
for(j=0;j<n;j++)
scanf("%d",&a[i][j]);
}

//main function
void main()
{
int a[10][10],i,j,n;

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

//check if the matrix is symmetric or not
for(i=0;i<n;i++)
for(j=i+1;j<n;j++)
if(a[i][j]!=a[j][i])
{
printf("Not symmetric");
return;
}
printf("Symmetric");
getch();
}

History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.

My 1st Program...


#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}

Next Step...


#include
#include

void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");

printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");

getch ();

}

Hits!!!
