Patrice fixed your compilation problem. However, the code, as it stands, still has flaws. See the notes below:

C

//Header file
#include <stdio.h>
//Main program 
int main()
{
   //Declaration of variables.
   int n, r=0 , rev; // Note: r is also initialised

   // Initialization of variables 

   // Note you didn't initialise 'rev' here

   scanf("%d",&n);
   //Processing of variables 
   r = n % 10;
   rev = rev * 10 + r ; // Note you are using the uninitialised 'rev'
   n =n / 10; // Note: this operation is pointless, since you didn't use 'n' afterwards
   //Output 
  printf ("%d",rev); // Note: here the output is 'unpredictable' since you've used the uninitialised 'rev'
  return 0;
}

Solution 1

I would try to

C++

//Header file
#include <stdio.h>
{ // remove this line
//Main program 
 int main()
{
   //Declaration of variables.
   int n,r=0 ,rev;
   // Initialization of variables 
   scanf("%d",&n);
   //Processing of variables 
   r = n%10;
   rev = rev*10+r;
   n =n/10;
   //Output 
  printf ("%d",rev);
 return 0;
  }   
} // remove this line
