Could you explain each line of C++ code used to display on a LCD step by step?

#include "mbed.h" #include "LCD_DISCO_L476VG.h"

LCD_DISCO_L476VG lcd;

DigitalOut led_green(LED1);

int main() { uint8_t DisplayedString[7] = {0}; uint8_t title[] = " DISCOVERY STM32L476"; printf(" Hello "); led_green = 1; lcd.Clear(); lcd.DisplayString((uint8_t *)"HELLO"); ThisThread::sleep_for(5000); led_green = 0; while(1) { printf("Scroll sequence "); lcd.Clear(); lcd.ScrollSentence(title, 1, 400); lcd.Clear(); led_green = !led_green; for(uint32_t BarNumber = 0; BarNumber => printf("BAR = %d ", BarNumber); sprintf((char *)DisplayedString, "BAR %d", BarNumber); lcd.DisplayString(DisplayedString); lcd.BarLevelConfig((uint8_t)BarNumber); ThisThread::sleep_for(1000); } } }

This is C++ code on mbed used to write to a LCD on a Disco- L476VG microcontroller. Could you just explain what each line of code does? (like -this line Prints 'Hello' to the LCD-) But for each line so I can learn how they came up with the code.
