Memory Allocation & Array Usage in C++ Classes Tutorial #22 #Cplusplus

This blog discusses memory allocation for objects and the use of arrays in C++. Memory is allocated to variables of a class when an object is created, but not when the class is declared. Each object has individual copies of variables, but functions are shared among objects. Arrays are useful for storing multiple values of the same type in a sequential order. An example program demonstrates the use of arrays in classes, where a Shop class is created with integer array variables for item IDs and prices. Functions like initCounter, setPrice, and displayPrice are defined within the class. The setPrice function takes input for item IDs and prices from the user, incrementing a counter variable. The displayPrice function prints the values of item IDs and prices using a loop. In the main function, an object of the Shop class is created, and the functions are called to set prices for items and display them. Loops can be used to call functions multiple times. Overall, this blog highlights the importance of memory allocation for objects and the practical use of arrays in classes in C++.
