help about byte combine pls

hello.i have 2 byte .example a and b.and i want to combine this bytes in x(word) variable.or how can i do this shortly.i try to use byte a; byte b;

word(x); word(a,b); but it doesnt work always x =0 can u help me pls

Try this:-

void setup()
{
    Serial.begin(115200);
    byte a = 2;     // Will be high byte
    byte b = 3;     // Will be low byte
    
    word x = word(a, b);
    Serial.println(x, BIN); // Prints: "1000000011"
}

void loop(){}

Edit: Incidentally, a 'word' variable is just an 'unsigned int', so this is the same:-

void setup()
{
    Serial.begin(115200);
    byte a = 2;     // Will be high byte
    byte b = 3;     // Will be low byte
    
    unsigned int x = word(a, b);
    Serial.println(x, BIN); // Prints: "1000000011"
}

void loop(){}

thank you .its working now.thanks a lot
