💻 Day 85: Loops Concept in C – Hinglish

 

💻 Loops Concept in C – 

👉 Aaj hum seekhenge:
✅ Loop kya hota hai
✅ Types of loops
✅ Real-life examples
✅ Simple programs
(Very important topic 💯)

---

📌 Loop kya hota hai?

👉 Jab kisi kaam ko bar-bar repeat karna ho,
toh hum loop use karte hain.

➡️ Simple words me:
Loop = Repeat process 🔁

🧠 Example (Real Life):

• 1 se 10 tak ginti bolna

• Attendance list print karna

• Table print karna

🧩 Types of Loops in C

1️⃣ for Loop

👉 Jab hume pata ho kitni baar loop chalega.

Syntax:

for(initialization; condition; increment/decrement) {
    // code
}

Example:

#include <stdio.h>
int main() {
    int i;
    for(i = 1; i <= 5; i++) {
        printf("%d\n", i);
    }
    return 0;
}

---

2️⃣ while Loop

👉 Jab condition pe depend ho.

Syntax:

while(condition) {
    // code
}

Example:

#include <stdio.h>
int main() {
    int i = 1;
    while(i <= 5) {
        printf("%d\n", i);
        i++;
    }
    return 0;
}

---

3️⃣ do-while Loop

👉 Kam se kam ek baar chalega.

Syntax:

do {
    // code
} while(condition);

Example:

#include <stdio.h>
int main() {
    int i = 1;
    do {
        printf("%d\n", i);
        i++;
    } while(i <= 5);
    return 0;
}

---

🆚 Difference (Simple Table)

Loop	Use
for	Fixed times
while	Condition based
do-while	At least once

---

🧪 Practice Questions

✅ Theory:

1. Loop kya hota hai?

2. for, while, do-while me difference likho.

3. do-while loop ki special feature kya hai?

✅ Practical:

👉 Program likho:

• 1 se 10 tak number print

• Table of 5

• Sum of first 10 numbers

---

📝 Short Notes (Exam ke liye)

👉 Loop = repetition
👉 for, while, do-while = types of loops
