What are the bitwise operators and how can they be used in C++ software? Do you know what a bitwise operation is? What is bit shifting? How can we use the AND, OR, XOR, NOT bitwise operators? In this post we will answer these questions..
A short explanation of what a ‘bit’ is in computer terminology
The construction, size, complexity and the general form of CPUs have changed enormously…
How can we read a formatted wstring in a modern C++ app? How can I convert a wstring to a wstringstream? What is std::wstringstream? What are the methods that can be used to read a formatted string in general? Is there a simple example of how to read formatted wide string?
How can I find a first or last character that is not a character that i am searching in a string? What kind of methods I can use in my C++ apps to find the first character equal to NONE of the characters in the given string in a std::string? How can I use…
How can I search only a single character in a string in my C++ apps? What kind of methods I can use to find a character in a std::string? How can I use find_first_of(), find_last_of() methods with strings?
Modern C++ uses Strings, Wide Strings, and Unicode Strings to support worldwide languages. Strings (std::string) uses char as the character type which means they are ASCII chars and…
How can we use Time when writing C++ software? How can we obtain local time or UTC time in our C++ apps? How can we get each property of a time such hours, mins, seconds?
In programming we have two important parameters that we use, which are Date and Time properties. The…
Lambda Expressions allow users to write an inline expression that can be used for short snippets of code in your C++ app which are not going to be reused and don’t require naming. The Lambda Expression construct is introduced in C++ 11 and further developed in the C++17…
How can I read a text file in a C++ app? How can I write to a text file in C++? How can I append to a text file in C++? How can I use open() method for the ifstream? How can I use open() method for the ofstream? How can I use open() method for the fstream? What is the syntax of ofstream open()? What is the syntax of ifstream open()? What is the syntax of fstream open()? How can I write and read to…
If you construct an object, sometimes you need operations to deconstruct. Destructors not only used in classes but also used with struct and union data types. Do you want to learn what a Pure Virtual Destructor is in a C++ App, or what kind of methods we have that we can…
Do you want to use DOS commands to operate on directories or folders? Do you know that you can use system commands in C++ to operate on folders? How can we get our C++ App to list files of a folder, how we can copy, rename, delete, or move directories? Can we set the access…
How can we use Time in our C++ App? How can we obtain local time or UTC time? How can we get each individual property of the clock (hours, mins, seconds)?
When we write programs, it’s very common to come across two important parameters, which are Date and Time properties. The Date and Time property is obtained from a timer or time module which is a physical device on the hardware you are…
