I'm trying to convert a char array to a char. i used this code
char code[4] = {'1','2','3','4'};
char strcode[4];
void setup()
{
Serial.begin(9600);
}
void loop()
{
memcpy(strcode, code, 4);
Serial.println(strcode);
Serial.println("done");
delay(1000);
}
But for some reason when i read my serial monitor i get this:
1234
done
Why are there 2 squares behind it? Am I doing it wrong?
EDIT: For some reason stackexchange doesn't show the 2 squares but there are 2 squares behind 1234
