‼️Extra Sessions for Midterm Preparation‼️

Today we are going to organize an online lesson

💻 C++ Programming
⏰ Time: 21:00
Topic will be Functions

✅Be prepared, guys

@cpp_sirius👨‍💻

‼️We have changed the code

What will we learn today?

Functions:
— Function of functions
— Value-returning function
— void function
— Extra hard problems

‼️Join us‼️

// C++ dasturlash tili - funksiyalar tili

// 1. Parametrli funksiyalar;
// 2. Parametrsiz;

// 1. Value-returning (qiymat qaytaradigan)
// 2. Qiymat qaytarmaydigan (void)

// Global and local variables

// Value - qiymat parametrlari
// Ko'rsatkichlar parametrlari - Reference

// Funksiyadan chiqish
