good day guys. i was studying a particular block of code and came across an operator: ->. im not exactly sure what it does. i found some notes saying that ptr-> is equivalent to(*ptr). for the life of me i just cant see how that applies here. care to help? thanks

```
void init_Gyro1DKalman(struct Gyro1DKalman *filterdata, float Q_angle, float Q_gyro, float R_angle)
{
filterdata->Q_angle = Q_angle;
filterdata->Q_gyro = Q_gyro;
filterdata->R_angle = R_angle;
}
```

and here's the structure of gyro1dkalman

```
struct Gyro1DKalman
{
float x_angle,
x_bias;
float P_00,
P_01,
P_10,
P_11;
float Q_angle, Q_gyro;
float R_angle;
};
```
