Handle Based File Operations In C++ Builder

Handle based file read and write methods can be used in Modern C++, In C++ Builder. In Modern C++ we highly recommend you to use Modern File Operations to support your application on all platforms and for the some benefits of using these methods like supporting worldwide languages by using UnicdeStrings etc. If you dont need these, you can easily use old methods in C++ Builder with GUIs. You can browse a file by using OpenDialog() component and read lines of a file by using fgets() or fscanf() or we can get parameters by using sscanf() function.
