How To Use Strings And File Names In C++ Software?

pexelsmaxfischer5212700

Hello to All Beginner and Professional C++ Developers,

C++ Builder is a modern, professional IDE with great C and C++ compilers for a range of different OS platforms to create great C++ software. The C++ Builder IDE and runtime have a lot of modern features. This is another hot week of summer with a lot of new C++ posts. Every post here gives you more details about the methods of modern C++ and C++ Builder. Today, we will continue our series on strings of classic C++ as well as path manipulation routines of C++ Builder. Firstly, we explain how to use find method with wstrings, then we explain how to copy wstring to wide char array in modern ways of C++, and we teach how to use find_first_not_of method in string searches. In path manipulations routines section, we explain how to use ExtractFileName method and the GetFileName Method with UnicodeStrings or Strings in C++ Builder.

What is LearnCPlusPlus.org and how does it relate to modern C++ software?

LearnCPlusPlus.org is packed full of great articles for professionals and beginners alike. The posts vary from articles suitable for people who are just starting to learn C++ – basics like string handling, pointers, loops, and all those fundamental building blocks of this rich and powerful programming language – too much more in-depth and advanced subjects like artificial neural networks and AI, along with the math behind it. Our focus is on the C++ language, particularly modern C++, and will work with almost any environment and IDE software you can choose although, of course, we believe RAD Studio C++ Builder is the best option!

If you are new to RAD Studio, we think these posts may help you as much as a rapid introduction to programming in C++, all the way to the most robust, modern, and latest techniques for those more experienced with the language. For those who are perhaps wanting to expand their knowledge with the most up-to-date features, routines, and methodologies this is a great little boost (pun intended) to your C++ knowledge. The new RAD Studio 11C++ Builder 11, Delphi 11 are released with great new features and we are developing and testing new examples for you with the latest RADS 11 that means.LearnCPlusPlus.org examples are working well with the latest C++ Builder.

This week there is a new release of RAD Studio / C++ Builder version 11.1.5 with Code Insight Update,

  • How can I use copy() method of std::wstring in a C++ application?
  • How can I copy a wide string to a wide char array?
  • How can I find a first or last character that is not a character that i am searching in a string in my C++ app?
  • What kind of methods I can use to find the first character equal to none of the characters in the given string in a std::string?
  • How can I use find_first_not_of() methods with strings?
