🚀 Function with Pointers in C++ – Zomato Delivery Style me!

💡 Function with pointers ka matlab baa: ek function jo pointer ke through data receive kare, update kare aur direct delivery ke jaise value change kar de! Samjho ek delivery boy ke paas address aa gaya aur usse order update kar de.

🔰 Basic Concept:

C++ me jab hum pointer ke through function me value pass karat bani, tab function asli value ke address se kaam karta baa – matlab asli value update ho sakta baa! Aisan hi samjho: Zomato ke app me order de rahe hai, aur restaurant se order me thoda modification chahi – wo update ho jai directly!

🔍 Code Example: "Order Update Function" 🍱

#include <iostream>
using namespace std;

// Function jo pointer se value receive kare ke kaam karela
void updateOrder(int* orderAmount) {
    // Thodi delivery fee add kar diye – value update kar diye jaise bonus tip!
    *orderAmount = *orderAmount + 50;

    // Punchline:
    cout << "Order update bhaiya: Ab order amount ho gaya: " << *orderAmount << " Rs" << endl;
}

int main() {
    int order = 250;  // Initial order amount
    cout << "Pehle order amount: " << order << " Rs" << endl;

    // Function ko order ke address pass karat bani
    updateOrder(&order);

    cout << "Final order amount (after update): " << order << " Rs" << endl;
    return 0;
}
  

🟢 Output:

Pehle order amount: 250 Rs
Order update bhaiya: Ab order amount ho gaya: 300 Rs
Final order amount (after update): 300 Rs
  

🍽️ Bhojpuri Analogy:

• Order ke pehla amount: 250 Rs – Jaisan customer ne order place kia.
• updateOrder() function: Restaurant wala function – jiska paas order ka address hai aur jisme kuch extra charges (delivery fee) add kia jaata.
• Final order amount: Badha ke 300 Rs – Direct update ho gaya order ke value!

😆 Joke Time:
"Jab pointer se function ke call hota, restaurant ke manager bole: 'Order me thoda twist add kar dete hain, bonus tip samajh ke!'"

📌 Key Points:

• Call by Address: Function me pointer ke through call karke asli value ko update karte hai.
• Efficient Delivery: Jaise delivery boy order ko directly customer ke ghar le ke jata, waise hi pointer function me value ko directly manipulate karta baa.
• Memory Ka Khayal: Pointers se function efficient banta, lekin dhyan rahe – address pass karna matlab asli data ke saath khelna!
