Challenge 4: Share the Candies! 🚀

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

🎬 The Story

Robo starts with $8$ candies. He gives away $3$ candies. Help Robo read two numbers, subtract the second number from the first, and calculate the remaining candies.

📝 The Algorithm

1. Start (Begin)
2. Read Number1 and Number2 (Input)
3. Subtract Number2 from Number1 and store result in diff (Process)
4. Display diff (Output)
5. Stop (End)

📊 The Flowchart

💻 From Flowchart to Code

Here is how to subtract two input numbers in Python, Java, and C:

Python

# Read two numbers
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
# Subtract
diff = num1 - num2
# Display result
print("Difference:", diff)

Java

import java.util.Scanner;

public class SubtractNumbers {
    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();
        // Calculate difference
        int diff = num1 - num2;
        System.out.println("Difference: " + diff);
    }
}

C

#include <stdio.h>

int main() {
    int num1, num2, diff;
    printf("Enter first number: ");
    scanf("%d", &num1);
    printf("Enter second number: ");
    scanf("%d", &num2);
    // Calculate difference
    diff = num1 - num2;
    printf("Difference: %d\n", diff);
    return 0;
}
