generic type container without using void* ptr

[tryfekid]

I need to know if there's a way to store generic types without using the void* pointer. I've seen ways of using void* pointer to hold the generic type but I'm looking for a different approach. Here's what I mean:

struct var_info
{
string var_name;
string data_type;
(numerical type here) value;
};

"value" can be any numerical type: int, short, long, double, float, etc... I need to do this because I want to put this info into a parameterized container such as a vector, or hash table. Please let me know if this is possible and any help is appreciated.

how bout

typedef byte char;
union GenericType
{
byte b
short s;
int i;
long l;
float f;
double d;
};

struct var_info
{
string var_name;
string data_type;
GenericType value;
};

that may work for you... you just have to make sure you set it properly because if you set an int, and compare it as a float you will not get the desired result.
