Write a C program to test Palindrome Numbers.



#include <stdio.h>
 
void main()
{
   int n, rev = 0, temp;
 
   printf("Enter a number to check if it is a palindrome or not\n");
   scanf("%d",&n);
 
   temp = n;
 
   while( temp != 0 )
   {
      rev = rev * 10;
      rev = rev + temp%10;
      temp = temp/10;
   }
 
   if ( n == rev )
      printf("%d is a palindrome number.\n", n);
   else
      printf("%d is not a palindrome number.\n", n);
 }

Write a C program for matrix multiplication.



#include <stdio.h>
 
void main()
{
  int m, n, p, q, c, d, k, sum = 0;
  int first[10][10], second[10][10], multiply[10][10];
 
  printf("Enter the number of rows and columns of first matrix\n");
  scanf("%d%d", &m, &n);
  printf("Enter the elements of first matrix\n");
 
  for (  c = 0 ; c < m ; c++ )
    for ( d = 0 ; d < n ; d++ )
      scanf("%d", &first[c][d]);
 
  printf("Enter the number of rows and columns of second matrix\n");
  scanf("%d%d", &p, &q);
 
  if ( n != p )
    printf("Matrices with entered orders can't be multiplied with each other.\n");
  else
  {
    printf("Enter the elements of second matrix\n");
 
    for ( c = 0 ; c < p ; c++ )
      for ( d = 0 ; d < q ; d++ )
        scanf("%d", &second[c][d]);
 
    for ( c = 0 ; c < m ; c++ )
    {
      for ( d = 0 ; d < q ; d++ )

          sum = sum + first[c][k]*second[k][d];
        }

        printf("%d\t", multiply[c][d]);

Write a C program to find transpose a matrix.



#include <stdio.h>
 
void main()
{
   int m, n, c, d, matrix[10][10], trans [10][10];
 
   printf("Enter the number of rows and columns of matrix ");
   scanf("%d%d",&m,&n);
   printf("Enter the elements of 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++ )
      {
         trans[d][c] = matrix[c][d];
      }
   }
 
   printf("Transpose of entered matrix :-\n");
 
   for( c = 0 ; c < n ; c++ )
   {
      for( d = 0 ; d < m ; d++ )
      {
         printf("%d\t",trans[c][d]);
      }  
      printf("\n");
   }
 }

Write a C program to add two matrix.



#include <stdio.h>
 
void main()

      for ( d = 0 ; d < n ; d++ )
         sum[c][d] = first[c][d] + second[c][d];
 
   printf("Sum of entered matrices:-\n");
 
   for ( c = 0 ; c < m ; c++ )
