Write a ‘C’ program for multiplication of two m*n matrices.

   clrscr();
   printf("enter the number of row: ");
   scanf("%d",&m);
   printf("enter the number of column :");
   scanf("%d",&n);
   printf("enter the first matrix elements\n");
   for(i=0;i<m;i++)
   {
      for(j=0;j<n;j++)
      {
scanf("%d",&a[i][j]);
      }
   }

      }
   }
   printf("multiplication of matrix is \n");
   for(i=0;i<m;i++)
