VSC vs Arduino IDE C++ compilation fail

Can you tell me about an error. I have scatch for arduino nano, this code compilation on Arduino IDE! But doesn't work on VSC 'ai0' was not declared in this scope 'ai1' was not declared in this scope.

  
void setup() {
Serial.begin (9600);

pinMode(2, INPUT_PULLUP); // internal pullup input pin 2 

pinMode(3, INPUT_PULLUP); // internalเป็น pullup input pin 3
//Setting up interrupt
//A rising pulse from encodenren activated ai0(). AttachInterrupt 0 is DigitalPin nr 2 on moust Arduino.
attachInterrupt(0, ai0, RISING);
 
//B rising pulse from encodenren activated ai1(). AttachInterrupt 1 is DigitalPin nr 3 on moust Arduino.
attachInterrupt(1, ai1, RISING);
}
 
void loop() {
// Send the value of counter
if( counter != temp ){
Serial.println (counter);
temp = counter;
}
}
 
void ai0() {
// ai0 is activated if DigitalPin nr 2 is going from LOW to HIGH
// Check pin 3 to determine the direction
if(digitalRead(3)==LOW) {
counter++;
}else{
counter--;
}
}
 
void ai1() {
// ai0 is activated if DigitalPin nr 3 is going from LOW to HIGH
// Check with pin 2 to determine the direction
if(digitalRead(2)==LOW) {
counter--;
}else{
counter++;
}
}``

#include <Arduino.h>

void ai0() {
// ai0 is activated if DigitalPin nr 2 is going from LOW to HIGH
// Check pin 3 to determine the direction
if(digitalRead(3)==LOW) {
counter++;
}else{
counter--;
}
}
 
void ai1() {
// ai0 is activated if DigitalPin nr 3 is going from LOW to HIGH
// Check with pin 2 to determine the direction
if(digitalRead(2)==LOW) {
counter--;
}else{
counter++;
}

void setup() {
Serial.begin (9600);

pinMode(2, INPUT_PULLUP); // internal pullup input pin 2 

pinMode(3, INPUT_PULLUP); // internalเป็น pullup input pin 3
//Setting up interrupt
//A rising pulse from encodenren activated ai0(). AttachInterrupt 0 is DigitalPin nr 2 on moust Arduino.
attachInterrupt(0, ai0, RISING);
 
//B rising pulse from encodenren activated ai1(). AttachInterrupt 1 is DigitalPin nr 3 on moust Arduino.
attachInterrupt(1, ai1, RISING);
}
 
void loop() {
// Send the value of counter
if( counter != temp ){
Serial.println (counter);
temp = counter;
