Question

With structure :

struct element_data
{
    int size;
    int type;
    int nID;
    int attribute;
    double fValue;
    int mode;
    bool bTemp;
};

…I have to manually initialize all members with zero :

inline element_data() : //Empty constructor
    size(0),
    type(0),
    nID(0),
    attribute(0),
    fValue(0),
    mode(0),
    bTemp(false)
{}

Too many commands, that may slowdown my calculator. Is there any other way which can do this? For example with a single command all values will take the zero values…

As your struct element_data is POD you could initialize members to default value in two ways:

element_data ed = element_data();

OR

element_data ed = {};

All integer members will be initialized to 0 and bool will be initialized to false.
