[calmesriram]

Hi,
I am new to Eos (iam using jungle Testnet ). i have tried a small contract which given below. adding two number
and result storing in a variable c.after deploying the contract. passing a two argument to contract
function.

how do i access the variable c (which is result). if not is there is any other way to access result.

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>
using namespace eosio;
class add : public contract
{
public:
uint64_t c;
using contract::contract;
void sum(uint64_t a, uint64_t b)
{
c = a + b;
print("Sum is ",c);
}

void gdata()
{
print(c);
}
};

EOSIO_DISPATCH(add, (sum) (gdata))
