void main()
{
int a[10][10],m,i,j,sum=0;
clrscr();
printf("Enter order of square matrix ");
scanf("%d",&m);
printf("Enter values of matrix\n");
for(i=1;i<=m;i++)
{
 for(j=1;j<=m;j++)
 {
  printf("Enter value of a[%d][%d] ",i,j);
  scanf("%d",&a[i][j]);
 }
}
for(i=1;i<=m;i++)
{
 for(j=1;j<=m;j++)
 {
  if(i>j)
  sum=sum+a[i][j];
 }
}
