What is parameter constructor?
C++ permits us to achieve this objects bt passing argument to the constructor function when the object are created . The constructor that can take arguments are called parametrized constructors Example:- class abc { int m,n; public: abc(int x,int y); //paramererise constructor ................ ................. }; abc::abc(int x,int y) { m=x;n=y; }
When only a copy of the argument's value is passed into the paremeter variable?
By default, a copy of the argument's value is passed into the parameter variable. This is "call by value" semantics, and the called function can do whatever it wants with the parameter, but it cannot alter the original copy. Sometimes, in C and C++, you can pass the address of the value instead. This is "call by address" semantics, but the called function must be designed to handle it - in this case, the called function can alter the original value. (Actually, it is always "call by value" - what we call "call by address" is simply passing the value of the address, a subtle distinction which is important to understanding the language.)
Why is parameter passing useful to programmers?
Because all software is written using functions and classes. If you do not know how to pass data from class to class, to function you are not a programmer.
