What is context? What are context pointers? How can you use context pointers for product recommendation? Explain with a detailed workout example. Also, give example where market basket analysis contributes to context for product recommendation.
What is context?
You can use the context operator in C++ to qualify a breakpoint location, variable name, or expression. The context operator is useful for specifying a name from an outer scope that is otherwise hidden by a local name.What are context pointers?
It is common for C-style APIs that take a function pointer as a callback to also take a pointer-sized argument as a "context", that is passed into the callback so that information can be passed from the call-site to the invocation of the callback.
How do you initialize a pointer example?
You need to initialize a pointer by assigning it a valid address. This is normally done via the address-of operator ( & ). The address-of operator ( & ) operates on a variable, and returns the address of the variable. For example, if number is an int variable, &number returns the address of the variable number.
What is void variable in C?
void (C++) When used as a function return type, the void keyword specifies that the function does not return a value. When used for a function’s parameter list, void specifies that the function takes no parameters. You cannot declare a variable of type void.
Are all pointers the same size?
Pointers are always of the same size, irrespective of the datatype they point to. On a 64-bit Ubuntu system with an 8 GB RAM (my system), this size is 8 bytes. This is the size of void pointers, int pointers, and char pointers alike, even long pointers and float pointers.
Why is size of void 1?
In GNU C, addition and subtraction operations are supported on pointers to void and on pointers to functions. This is done by treating the size of a void or of a function as 1. A consequence of this is that sizeof is also allowed on void and on function types, and returns 1.

What is the void data type?
Overview. The void data type, similar to the Nothing data type described earlier, is the data type for the result of a function that returns normally, but does not provide a result value to its caller.
What is size of void in C?
If the system is 16-bit, size of void pointer is 2 bytes. If the system is 32-bit, size of void pointer is 4 bytes. If the system is 64-bit, size of void pointer is 8 bytes.
What is void star in C?
void pointer in C / C++ A void pointer is a pointer that has no associated data type with it. A void pointer can hold address of any type and can be typcasted to any type. int a = 10; char b = ‘x’ ; void *p = &a // void pointer holds address of int ‘a’
How can you use context pointers for product recommendation?
Product recommendations are part of an ecommerce personalization strategy wherein products are dynamically populated to a user on a webpage, app, or email based on data such as customer attributes, browsing behavior, or situational context—providing a personalized shopping experience.
Similar products:
This product recommendation tactic suggests products that are similar to the product on the current page, based on the contents of product details such as name, description and tags.
Why does it work?
This tactic allows shoppers to see a range of alternative products similar to the one they're browsing, allowing them to find the one that best suits their needs.
For retailers who frequently add new or one-off products to their inventory, this tactic works well since you can immediately include recently added items to your recommendation strategy without any manual tagging or customer behavioral data.
Space NK utilize this type of recommendation on their product pages by suggesting different types of the same product.
In market basket analysis (also called association analysis or frequent itemset mining), you analyze purchases that commonly happen together.
For example, people who buy bread and peanut butter also buy jelly. Or people who buy shampoo might also buy conditioner.
