arduino communicate with C++ (code blocks)

Using Arduino Interfacing w/ Software on the Computer
1

I have an Arduino and I would like to communicate with my computer. I would like to use usb (COM3) ( I think it is the easiest way). I use C++ ( Code Blocks) on my computer. I wan't to send an variable from computer to my arduino.

I've written the Arduino code:

// receiver
int data;

void setup() {
Serial.begin(9600);
pinMode (13, OUTPUT);
}

void loop() {
if (Serial.available()) {
data = Serial.read();
if (data==1){
digitalWrite(13, HIGH);
delay(100);
}
}
digitalWrite(13, LOW);
}

I want to write the sender code in C++ ( Code Blocks) which send an variable (data=1) .

Can you help me?

I think you need to import the serial library.
