You also need to :
   mpz_init(a);
   mpz_init(b);

> gmp_printf("enter the large no.");

For clarity, make that:
   gmp_printf("enter the first large no.");

> gmp_scanf("%Zd",a);

And then also include:
   gmp_printf("enter the second large no.");

> gmp_scanf("%Zd",b);
> mpz_add(c,a,b);

That's possibly all that's wrong. If you remove the '#include<iostream>' and 
the 'using namespace std;' the program builds and executes fine as a C 
program. (Beyond that, I haven't checked.)
