💻 Day 84: Conditional Statements in C – Hinglish

 

💻 Conditional Statements in C – 

👉 Aaj hum seekhenge:
✅ Conditional statement kya hai
✅ Types (if, if-else, else-if, switch)
✅ Examples
(Programming ka very important topic) 💯

---

📌 Conditional Statement kya hai?

👉 Jab program me condition lagate hain,
ki agar ye hoga to ye kaam karo, warna kuch aur karo.

➡️ Simple words me:
Condition = Agar / Nahi to logic.

🧩 Types of Conditional Statements

1️⃣ if Statement

👉 Sirf condition true hone par code chalega.

Example:

#include <stdio.h>
int main() {
    int a = 10;
    if (a > 5) {
        printf("A is greater than 5");
    }
    return 0;
}

---

2️⃣ if-else Statement

👉 Agar condition true ho to if, warna else chalega.

Example:

#include <stdio.h>
int main() {
    int a = 3;
    if (a > 5) {
        printf("A is greater than 5");
    } else {
        printf("A is not greater than 5");
    }
    return 0;
}

---

3️⃣ else-if Ladder

👉 Multiple conditions ke liye.

Example:

#include <stdio.h>
int main() {
    int marks = 75;

    if (marks >= 90) {
        printf("Grade A");
    } 
    else if (marks >= 60) {
        printf("Grade B");
    } 
    else {
        printf("Grade C");
    }
    return 0;
}

---

4️⃣ switch Statement

👉 Multiple choices ke liye.

Example:

#include <stdio.h>
int main() {
    int day = 2;

    switch(day) {
        case 1:
            printf("Monday");
            break;
        case 2:
            printf("Tuesday");
            break;
        default:
            printf("Invalid day");
    }
    return 0;
}

🧪 Practice Questions

✅ Theory:

1. Conditional statement kya hai?

2. if aur if-else me difference likho.

3. switch statement kya hai?

✅ Practical:

👉 Program likho:

• Even / Odd number check

• Marks se grade print karo

---

📝 Short Notes (Exam ke liye)

👉 if = condition check
👉 else = otherwise
👉 switch = multiple choice
