It helps in protecting the data contained within the object from external manipulation and ensures that the object is always in a valid state. Default constructors: When no constructor is defined, the compiler generates a default constructor that initializes all data members to their default values...

VCL and FMX frameworks include libraries built to make you more productive. For example, no C++ developer enjoys string manipulation using the STL’s std::string methods, or loading data in UTF-8 and converting to wide strings for Windows before modifying a string with the WinAPI. Let’s no...
The syntax of SUBSTR manipulation function in SQL is SUBSTR(char, position, length) SUBSTR is identified as a substring or takes one portion from a string and then return them. CHAR specifies what should be used as the substring source. The position is defined as the starting of the substrin...
the string is to evaluate the string manipulation in text form. The string function supports and executes an atomic value that is not a simple node. The substring function has two string values that execute the specific string which is present in the user-given data. The other part of the ...
