// I have a structure

```
 typedef struct
 {
    uint8_t* data;
    uint16_t data_ln;
 } Struc_Data;

```

//a derived type from this struct

```
 Struc_Data    tx_struct;

```

// i have to initialize this 'tx\_struct' in constructor initializer list, i am not getting how

```
 Constr::Constr( ):
    tx_struct  (reinterpret_cast<uint8_t*>(nullptr), 0U)  //this does not work
 {

 }

```
