Challenge 6: Share Pizza Safely! 🚀

Welcome to this challenge! Work with Robo 🤖 to solve this problem step-by-step using algorithms and flowcharts.

🎬 The Story

Robo wants to share $4$ pizzas equally between $2$ children. Help Robo divide them, but make sure to check if the number of children is $0$ first, as dividing by zero is impossible!

📝 The Algorithm

1. Start (Begin)
2. Read Number1 and Number2 (Input)
3. Check if Number2 is 0 (Decision)
   • If Yes: Display "Cannot divide by zero" (Output), then go to step 6 (Stop)
   • If No: Proceed to step 4
4. Divide Number1 by Number2 and store in quotient (Process)
5. Display quotient (Output)
6. Stop (End)

📊 The Flowchart

Here, the pink Decision Diamond is introduced.

💻 From Flowchart to Code

Here is how to divide two input numbers with zero check safety in Python, Java, and C:

Python

num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))

# Check for division by zero
if num2 == 0:
    print("Cannot divide by zero")
else:
    ans = num1 / num2
    print("Quotient:", ans)

Java

import java.util.Scanner;

public class DivideNumbers {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter first number: ");
        int num1 = sc.nextInt();
        System.out.print("Enter second number: ");
        int num2 = sc.nextInt();

        // Check for division by zero
        if (num2 == 0) {
            System.out.println("Cannot divide by zero");
        } else {
            double ans = (double) num1 / num2;
            System.out.println("Quotient: " + ans);
        }
    }
}

C

#include <stdio.h>

int main() {
    int num1, num2;
    printf("Enter first number: ");
    scanf("%d", &num1);
    printf("Enter second number: ");
    scanf("%d", &num2);

    // Check for division by zero
    if (num2 == 0) {
        printf("Cannot divide by zero\n");
    } else {
        float ans = (float)num1 / num2;
        printf("Quotient: %.2f\n", ans);
    }
    return 0;
}
