A Complete Guide To Programming In C++ – Basics

slide4 4

C++ is one of the most powerful programming languages as well as being one of the World’s most popular. Using a fast, efficient and reliable C++ IDE is very important for beginners and professionals since it helps C++ developers in remembering which language features exist, how to use them, and even detect errors when we get it wrong. Over the course of the next few weeks, we’re going to release a series of articles which will take you from your very first steps with C++, through the basics, to more advanced topics. We’ll be using RAD Studio and C++ Builder as our C++ IDE and you’re going to learn how to create C++ programs for all platforms including Windows desktop as well as mobile apps.

Complete Guide To Programming Basics In C++

In general most program code is in the form of lines of text. That means you can read code in any editors i.e. with Notepad, Word, etc. on Windows. C and C++ Compilers, compiles (converts) these lines to machine code that directly runs in that operating system and links as a executable (*.exe) file. A Compiler (C or C++ Compiler, etc.) is a computer program that converts one programming language into executable machine code with a linker. Such code may not be as fast as assembler code, but the difference in speed is very small because both machine code and compiler-based code in text form are much more compatible with other CPU/GPUs and/or with other Operating Systems when you compile them on a machine. This is one reason why C++ is the fastest and most powerful programming language. Interpreted programming languages run inside executable applications like Java, Python or Visual Basic. This is why they are slower when executing operations, as they need to use compiled libraries for faster operations. Again, they mostly they use C/C++ compilers to build these libraries. Using an interpreted programming language is like being carried by a runner, while a compiled (non-interpreted) programming language is like running itself. This subtle difference turns into a huge gap when you run the same routine (i.e. for face recognition) millions of times a millisecond.

Complete Guide To Programming Strings In C++

The basic_string (std::basic_string and std::pmr::basic_string) is a class template that stores and manipulates sequences of alpha numeric string objects (char,w_char,…). For example, str::string and std::wstring are the data types defined by the std::basic_string<char>. In other words, basic_string is used to define different data_types which means a basic_string is not a string only, it is a namespace for a general string format. A basic string can be used to define string, wstring, u8string, u16string and u32string data types. Let’s see how we can use them in different operations.
