💻 Day 89: Final Revision – C Language (Hinglish)
💻 Final Revision – C Language
👉 Aaj ka day hai Final Revision 🎯
Yani jo kuch bhi humne C language me padha hai, uska short + clear recap 💯
🧠 Part 1: C Language Overview
✅ C Language = Programming language
✅ Creator = Dennis Ritchie
✅ Use = Software, OS, Programs
🧩 Part 2: Important Concepts Revision
1️⃣ Variables & Data Types
👉 Variable = Data store karne ka box.
Example:
int a = 10;
float b = 5.5;
char c = 'A';
2️⃣ Input & Output
scanf("%d", &a);
printf("%d", a);
3️⃣ Operators
Types:
Arithmetic: +, -, *, /, %
Relational: >, <, ==, !=
Logical: &&, ||, !
Assignment: =, +=, -=
Increment/Decrement: ++, --
4️⃣ Conditional Statements
👉 if, if-else, else-if, switch
Example:
if(a > b) {
printf("A is greater");
}
5️⃣ Loops
👉 for, while, do-while
Example:
for(i = 1; i <= 5; i++) {
printf("%d", i);
}
6️⃣ Simple Programs
✔ Even/Odd
✔ Largest number
✔ Table
✔ Sum
7️⃣ Errors & Debugging
👉 Types of errors:
Syntax error
Runtime error
Logical error
👉 Debugging = Errors fix karna.
🧪 Part 3: Important Exam Questions
✅ Theory Questions:
C language kya hai?
Variable aur data type explain karo.
Operators ke types likho.
if-else statement explain karo.
Loop kya hota hai? Types likho.
Error aur debugging me difference likho.
✅ Practical Questions:
Program to add two numbers
Program to check even/odd
Program to print table
Program to find largest number
📝 One-Page Short Notes (Exam ke liye)
👉 C = Programming language
👉 Variable = Data storage
👉 if = Condition
👉 Loop = Repeat
👉 Error = Mistake
🎉 Final Motivation
🔥 Agar tumhe C language aa gayi,
to tum next level languages easily seekh sakte ho 😎
