C99 introduced a number of new functions, including inline functions, numerous new data sorts (which includes extensive extended int and a fancy type to signify sophisticated quantities), variable-duration arrays and flexible array members, improved support for IEEE 754 floating level, help for variadic macros (macros of variable arity), and assistance for a person-line opinions starting with //, as in BCPL or C++. Lots of of these experienced previously been implemented as extensions in quite a few C compilers.
If a different object needs to be established ahead of the copying can manifest, the copy constructor is made use of (Be aware: this consists of passing or returning objects by value). If a completely new item does not have to become developed ahead of the copying can manifest, the assignment operator is applied. Overloading the assignment operator
