If there are compilation errors, then fix them. Predict the output of the following programs. Similarly, references must be used for overloading some operators like ++.
#Using references in word how to
How to cite and manage references in Microsoft Word. Reference must be used to pass the argument in the copy constructor. How to add citations and references in research paper, thesis, how to use different citations s.
Together with the above reasons, there are few places like the copy constructor argument where pointer cannot be used. Also, members of an object reference can be accessed with dot operator (‘.’), unlike pointers where arrow operator (->) is needed to access members. ‘&’ operator is needed only at the time of declaration. 
See Why use Words built-in heading styles by Shauna Kelly. Words built-in heading styles are designed to use with cross-references in ways other styles are not. See Formatting Cross-References by Suzanne Barnhill, MVP. It is still possible to have references that don’t refer to a valid location (See questions 5 and 6 in the below exercise )Ģ) Easier to use: References don’t need a dereferencing operator to access the value. Although Cross-Reference fields are hyperlinks, they do not look like hyperlinks.
References are safer and easier to use:ġ) Safer: Since references must be initialized, wild references like wild pointers are unlikely to exist. How to use the automatic and instant features of Word to store your study references, insert citations, and generate a bibliography into your document. References being more powerful in Java is the main reason Java doesn’t need pointers. In Java, references don’t have the above restrictions and can be used to implement all data structures. There is no such restriction with pointers.ĭue to the above limitations, references in C++ cannot be used for implementing data structures like Linked List, Tree, etc. Pointers are often made NULL to indicate that they are not pointing to any valid thing.ģ) A reference must be initialized when declared. This is often done with pointers.Ģ) References cannot be NULL. References are less powerful than pointersġ) Once a reference is created, it cannot be later made to reference another object it cannot be reset. ISRO CS Syllabus for Scientist/Engineer Exam.
