Question 4 Why are typedef statements useful? Group of answer choices A typedef statement is a new style statement.  It comes with a lot of new C++ library features. A typedef statement is an old style statement.  It allows us to access old programs without any  problem. A typedef statement allows for flexibility when the data type for an item needs to be modified for a program depending on the application. The data type may simply be modified in the typedef statement rather than in the entire program. A typedef statement allows for anonymousness when the programmer does not want to reveal the data type for an item to anyone. A typedef statement allows a consistent data type for a program. This will not allow  any data type change.
