Comprehensive Guide to Implementing Multi-Factor Authentication
In an era where digital security is paramount, Multi-Factor Authentication (MFA) stands as a critical defense mechanism against escalating cyber threats. MFA, by definition, involves verifying a user’s identity by requiring multiple pieces of evidence before granting access to a system or application. This guide delves into the essentials of MFA, its pivotal role in […]
AI-Powered Code Completion for C++: Boosting Development Efficiency
The advent of Artificial Intelligence (AI) has ushered in a new era in the field of software development. AI’s integration into development tools has been a game-changer, particularly with the introduction of AI-powered code completion. This technology is not just a futuristic concept but a present-day reality that is reshaping how developers write code, especially […]
How to use #ifdef and #ifndef to check if an identifier has been defined
#ifdef, #ifndef and #endif are preprocessor directives which allow us to check wether or not a value has already been defined using the #define directive. This can be useful when you’re including files that may already have the same value defined using #define. Here’s an example that defines the value Whidbey only if it wasn’t defined before: #ifndef Whidbey#define Whidbey#endif Similarly, what’s between #ifdef and #endif is compiled […]
How to convert C++ variables to other data types using casting
There are several ways to convert C++ variables.Here is one method of converting an integer variable to a bool (boolean) variable: int MyInteger = 0;bool MyBool = (bool)MyInteger; And here is another way: int MyInteger = 0;bool MyBool = static_cast<bool>(MyInteger); In both cases, after the casting has been made, MyBool will contain the value false (since MyInteger was 0). If MyInteger was 1 or any other number […]
What is the difference between #include and #include “”?
In C++ it’s common to see two methods of including a header file: The difference between the two varies on the compiler you are using, however the rule of thumb is that the first version, between the “<” and “>”, will have the compiler search for filename in a series of predefined paths. It is the standard […]
How to swap two numbers without using a third variable
Using pointers you can easily swap two variables without using an additional variable to store a temporary value. This is because instead of swapping values, you can swap addresses, as shown in this function: void SwapSmart(int * a, int * b){*a = *a xor *b;*b = *b xor *a;*a = *a xor *b;}
Creating a collection class in C++
How to use a template to create a custom collection class and using the C++ std::vector STL library as well as the operator. I will expect you to understand how pointers, classes, templates and the operator works Introduction C++ comes with its own set of containers in the STL (Standard Template Libraries) libraries; (e.g. std::vector). It […]
