Inheritance aur composition
Fragile hierarchy banaye bina behavior reuse karo.
Idea, words aur real-world use pehle padho.
Example run karo, phir code task solve karo.
Quick check aur apne notes se concept explain karo.
- Inheritance and Composition ko apne words mein explain kar paana.
- Working example ko run aur modify kar paana.
Kisi question ka answer dene se pehle hum samjhenge ki Inheritance and Composition ka matlab kya hai, ye kahan useful hai aur example kaise behave karta hai. Naye words aate hi explain kiye gaye hain.
Idea ko samjho
Inheritance genuine is-a relationship model karta hai. Composition independent objects combine karta hai aur often easier hota hai.
Car ke paas engine composition se hota hai; electric car specialized car inheritance se hai.
Example ko step-by-step padho
- 1Program mein banaye gaye names aur values pehchaano.
- 2Har line ko top-to-bottom trace karo aur dekho wo kya change karti hai.
- 3Run Python dabane se pehle output predict karo, phir ek value change karo.
Kya yaad rakhna hai
- Fragile hierarchy banaye bina behavior reuse karo.
- Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.
Concept ko step-by-step dekho
Arrows use karke data ka safar samjho.
class StudentNaksha
Class data aur behavior ka naksha hoti hai.
Inheritance and Composition: working example
Example run karo, phir ek value change karke apni understanding test karo.
Kaunsa relationship composition favor karta hai?
Code ko complete karo
Computer ko composition se Keyboard do.
Key takeaways
- Inheritance genuine is-a relationship model karta hai. Composition independent objects combine karta hai aur often easier hota hai.
- Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
Pass the quick check and coding task to complete this lesson.
