Type it is an empty value data type and the last one is bool type which is true or false what is the role of pointers in c pointers in c are used for following purposes to access array elements for dynamic memory allocation and deal location while the program is executed call by reference to construct several data structures like tree graph linked list and so

On after that what are the major differences between c and c plus plus c plus plus supports inheritance and c does not support inheritance in c it focuses on a method or a purpose rather than data and in c plus plus it focuses on the data instead of method or procedure in c plus plus it can access modifiers but in c structures lacks excess modifiers in c plus
