💻 Day 87: Errors & Debugging in C – Hinglish

💻 Errors & Debugging in C –

👉 Aaj hum seekhenge:
✅ Error kya hota hai
✅ Types of errors
✅ Debugging kya hai
✅ Examples
(Very important topic 💯)

👉 Jab program me galti hoti hai,
aur program sahi se run nahi hota,
use Error kehte hain.

➡️ Simple words me:
Error = Programming mistake ❌

👉 Jab language rules galat ho.

#include <stdio.h>
int main() {
    int a = 10
    printf("Hello");
    return 0;
}

❌ Problem: Semicolon (;) missing
✅ Correct:

int a = 10;

👉 Program run hote time error.

int a = 10, b = 0;
printf("%d", a / b);

❌ Problem: Divide by zero
➡️ Program crash ho jayega.

👉 Program chalega, but output galat hoga.

int a = 5, b = 10;
printf("%d", a - b);

❌ Expected: addition
➡️ But subtraction likh diya.

👉 Program ke errors dhundhna aur fix karna = Debugging.

➡️ Simple words me:
Debugging = Error find + fix 🛠️

✅ Error message dhyan se padho
✅ Semicolon, brackets check karo
✅ Variables name check karo
✅ Logic verify karo
✅ Program step-by-step chalao

👉 Galti find karo:

#include <stdio.h>
int main() {
    int x = 10;
    if(x = 5) {
        printf("Hello");
    }
    return 0;
}
