How can I use substr() method of std::wstring? How can I get a substring of a string in a C++ app? Here are the answers with C++ examples.
Generally, as an introduction to C++, in addition to int, float, double there is another data type called string that we use for alphanumeric variables. In C++ there are several typedefs for common character types are provided: String types are defined in…
How can I swap strings? Can I use swap() method to std::string in the same ways as I can in std::wstring in a C++ App?
Generally, in Introduction to C++ lessons, examples are started withstringexamples and end with them, while Modern C++ usesStrings…
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…
Do you want to learn what is Eligible Copy Constructor or what kind of methods are available to declare and use an Eligible Copy Constructor? In this post, we will try to explain the Eligible Copy Constructor with examples. First, let’s remind ourselves of the Constructor and Copy Constructor meaning in C+++ software.
What is a Constructor in C++ software?
The Constructor in C++ is a…
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…
How can we convert one string to char array in Modern C++? Here are the answers with C++ software examples.
Generally, as an introduction to C++, in addition to int, float, double there is another data type, string that we use for alphanumeric variables. In C++ there are…
How can we print numbers in binary form? How can we set a bit in an integer? How we can set, clear, or toggle bits (binary digits) of a number? How can we change the nth bit of a number? In this post, we will answer these questions and use them in our own C++ software. First let’s remind ourselves where bits come from.
A brief background to CPU architecture
The construction, size…
What is Sigmoid Linear Unit in a neural network created with a C++ app? How can we use the SiLU function in an artificial neural network (ANN)? Where can we use SiLU in AI technologies? Let’s remind ourselves of the activation function and explain these terms.
What…
Strings are objects that represent sequences of alphanumeric characters. The standardstringclass provides support for such objects with an interface similar to that of an array of bytes. Strings specifically designed to operate with strings of single-byte…
How can we use Date in a C++ App?
In programming we have two important parameters that we frequently use – the 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 using. For example, a real-time clock (RTC) DS3231 module is used to count and ‘remember’ the correct time on IoTs. Other…
