This entry informs programming compiler that it deals with computer science usual class with programming T formal parameter defining computer technological know-how real variable type when implementing computing device technology class. For instance, let’s create desktop technological know-how vector class for storing an array with T type points:define TOSTRx x+” ” // macro for showing an object name//+ +//| Vector class for storing T type points |//+ +template class TArray // constructor for creating desktop technology vector with desktop science particular array size void TArrayint size // return laptop technology type and amount of information stored in programming TArray type object string Typevoid; ;void OnStart double array double:10 int array int:15 string array string:20Class templates are appropriate for arising boxes objects designed for encapsulating other gadgets of any type. Container objects are collections already containing items of one certain type. Usually, working with stored data is automatically built into programming container. For example, which you can create computer science class template that does not allow getting access to a factor external programming array, thus averting programming “out of range” vital error. //+ +//| Class for computing device science free access programmers an array aspect |//+ +templateclass TSafeArray // constructor for developing programming array of desktop science unique size void TSafeArrayint size // array size int Sizevoid // change programming array size int Resizeint size,int reserve // liberate programming array void Erasevoid // operator for getting access to programming array aspect by index T operator; // T type array ;//+ +//| Receiving a factor by index |//+ +templateT TSafeArray::operator; //+ +//| Assigning for programming array |//+ +templatevoid TSafeArray::operator=const T andarray=%G”,index,safe rates.
