How to show only respective data one single time?

while(readbyte(value)== TRUE)
                    {
                        buffer [count++] = queue.enqueue(value);
                        if(count == 128)
                            {count = 0;


                    if(parse_serial_data(buffer,22,&new_packet)==0)
                        {
                            if (new_packet.Address == 0x5C) {  //UM6_GYRO_PROC_XY

                                  // GYRO_PROC_X
                                MY_DATA_GYRO_PROC_X = (int16_t)new_packet.data[0]<<8; //bitshift it
                                MY_DATA_GYRO_PROC_X |= new_packet.data[1];
                                Data.Gyro_Proc_X = MY_DATA_GYRO_PROC_X*0.0610352f;
                                cout<<Data.Gyro_Proc_X<<"\t";
