How can I apply the concept of Array of object in arduino app

Projects Programming

My code:
class Numbers{
public:
void num(char x1[8],char x2[8],char x3[8] ,char x4[8],char x5[8],char x6[8],char x7[8]){
digitalWrite(pinA, x1);
digitalWrite(pinB, x2);
digitalWrite(pinC, x3);
digitalWrite(pinD, x4);
digitalWrite(pinE, x5);
digitalWrite(pinF, x6);
digitalWrite(pinG, x7);
};
};
Numbers[] n= new Numbers[10];
n[0].num('L''O''W','L''O''W','L''O''W' ,'L''O''W','L''O''W','L''O''W','H''I''G''H');
error type: decomposition declaration cannot be declared with type 'Numbers'

it's not clear why you're asking about an array of objects.

there are several problems with your code. consider

#define pinA    3
#define pinB    4
#define pinC    5
#define pinD    6
#define pinE    7
#define pinF    8
#define pinG    9

struct Number_s {
    void
    num (char x1,char x2,char x3 ,char x4,char x5,char x6,char x7)
    {
        Serial.println  ("num");

        digitalWrite (pinA, x1);
        digitalWrite (pinB, x2);
        digitalWrite (pinC, x3);
        digitalWrite (pinD, x4);
        digitalWrite (pinE, x5);
        digitalWrite (pinF, x6);
        digitalWrite (pinG, x7);
     };
};

Number_s num;

void
setup ()
{
    Serial.begin (9600);
    Serial.println ("setup");
    num.num(LOW, LOW, LOW , LOW, LOW, LOW, HIGH);
}

void
loop ()
{
}
