Question

SWITCH CASE, WHILE, DO WHILE STRUCTURES, using ARDUINO. Urgent Please!

Implement the following programs, attach a flow chart, and photos of its operation.
1. Read a number that represents the month and say what months it is.
2. Using the conditional "while" calculate the factorial of a number
3. Using the “do-while” conditional, make a program that prints all numbers from 1 up to a maximum number entered by the user.

PROGRAM 1:

void setup() {
     Serial.begin();
  // modify it according to yourself

}

void loop() {
     Serial.println("Input Month No :");
      int mon_num=Serial.read();
    
   switch(mon_num)
   {
        case 1:
               Serial.println("January");
               break;
        case 2:
               Serial.println("February");
               break;
        case 3:
               Serial.println("March");
               break;
        case 4:
               Serial.println("April");
               break;
        case 5:
               Serial.println("May\n");
               break;
        case 6:
               Serial.println("June");
               break;
        case 7:
               Serial.println("July");
               break;
        case 8:
               Serial.println("August");
               break;
        case 9:
               Serial.println("September");
               break;
        case 10:
               Serial.println("October");
               break;
        case 11:
               Serial.println("November");
               break;
        case 12:
               Serial.println("December");
               break;
        default:
               Serial.println("INvalid Input");
               break;
}

PROGRAM 2

void setup() {
       Serial.begin();
  // modify it according to yourself

}

void loop() {
    int n;
          Serial.println("ENTER A NUMBER:");
          n=Serial.read();
        int fact = 1;
        while(n>1)
        {
            fact=fact*n;
            n--;
        }
        Serial.println(fact);
}

PROGRAM 3

void setup() {
      Serial.begin();
  // modify it according to yourself
}

void loop() {
    int n;
    Serial.println("Enter number of elements you want to enter:");
          n=Serial.read();
          int a[n];

        int max = -99999;
        int i = 0;
        do{
            Serial.println("ENTER NUMBER:");
            Serial.println(i+1);
            a[i]=Serial.read();
            if(a[i] > max)
            {
                max=a[i];
            }
            i++;
        }while(i!=n);
        Serial.println("Larger number = ");
  Serial.println(max);
}
