An Open Motor skill is a skill which is performed in an unstable environment, where the start point is determined by the environment. In other words, the performer of the skill is NOT the one who choses when the skill and movement actions neeed to be peformed and executed, this is decided by other people or the environment.
A constructor is used to initialize class objects manually or automatically. Every time an object is created, it is initialized or given initial garbage values by a default implicit constructor. However, if one is to manually create one, the initial values, too, can be user defined. (You may refer to C++ Class Constructor and Destructor) class class_name{ public: int variable_to_define; void setvariable( int var) class_name(); // This is the constructor}; class_name::class_name(void) { variable_to_define=0; //user-defined initialization }
In C++, the constructor of automatic variables is called when the execution reaches the place of declaration. The destructor is called when it reaches the end of the given program block (program blocks are surrounded by curly brackets).
