How do I check what type of variable a variable is?

Something like;
if (typecheck(foo,int))
  {
  /* lol */
  }

Basically you need to create a list of all the available types and their sizes, and then use sizeof on your variable to determine which type it is.



char* types[4] = {
    "char",  // 1 byte
    "short",  // 2 bytes
    "long",  // 4 bytes
    "long long,"  // 8 bytes
};

int sizes[4] = { 1, 2, 4, 8 };


bool typecheck (variable, type)
{
    int i;

    for (; i <= 3; i++)
    {
        if (strcmp(types[i], type)
           return  sizes[i] = sizeof(variable) ? TRUE : FALSE;
    }

    return FALSE;
}
