assume the program must insert 4 elements from the key board and then do the following programs.sequential search(search one of the elements),using insertion sort(sort the element) and using selection sort(sort the element).

class CTest { public: void someMethod() { int nCount = 0; cout << "This is some method --> " << nCount; } }; int main() { CTest *pctest; pctest->someMethod(); return 0; } It will executes the someMethod() and displays the value too. how is it possible with our creating memory for the class . i think iam not creating object for the class. Thanks in Advance... Prakash
