Can I use standard data types like int, float and char with Vector class?
Java Language FAQsNo. You cannot use them as Vector deals with objects. Standard data types are not objects. However, you can use wrapper classes to convert standard data types to object so that they can be used with Vector. Vector v = new Vector(); // v.add(10); -- cannot be done v.add ( new Integer(10)); // int 10 is converted to object of type Integer class.

How to mix C and C++, C++ FAQ LiteIf you have an individual C function that you want to call, and for some reason you don't have or don't want to #include a C header file in which that function is declared, you can declare the individual C function in your C++ code using the extern "C" syntax. Naturally you need to use the full function prototype:
Related QuestionsHow can I create a C++ function f(int,char,float) that is callable by my C code?
How to mix C and C++, C++ FAQ LiteThe C++ compiler must know that f(int,char,float) is to be called by a C compiler using the extern "C" construct: The extern "C" line tells the compiler that the external information sent to the linker should use C calling conventions and name mangling (e.g., preceded by a single underscore). Since name overloading isn't supported by C, you can't make several overloaded functions simultaneously callable by a C program.
Related QuestionsWhat is the difference between VARCHAR, VARCHAR2 and CHAR data types?
SQL FAQ - Oracle FAQBoth CHAR and VARCHAR2 types are used to store character string values, however, they behave very differently. The VARCHAR type should not be used: CHAR should be used for storing fix length character strings. String values will be space/blank padded before stored on disk. If this type is used to store varibale length strings, it will waste a lot of disk space. SQL> CREATE TABLE char_test (col1 CHAR(10)); Table created. SQL> INSERT INTO char_test VALUES ('qwerty'); 1 row created.
Related QuestionsI want to use a char * pointer to step over some ints. Why doesn't "((int *)p)++;" work?
Frequently Asked Questions: C Language (abridged)In C, a cast operator is a conversion operator, and by definition it yields an rvalue, which cannot be assigned to, or incremented with ++. I have a function which accepts, and is supposed to initialize, a pointer, but the pointer in the caller remains unchanged.
Related QuestionsWhat are the criteria for choosing between short / int / long data types?
Newbie Questions / Answers Updated! , C++ FAQ LiteAnswer: It's usually a good idea to write code that can be ported to a different operating system and/or compiler. After all, if you're successful at what you do, someone else might want to use it somewhere else. This can be a little tricky with built-in types like int and short, since C++ doesn't give guaranteed sizes.

Related QuestionsWhat's the deal on sprintf's return value? Is it an int or a char *?
StdioThe Standard says that it returns an int (the number of characters written, just like printf and fprintf). Once upon a time, in some C libraries, sprintf returned the char * value of its first argument, pointing to the completed result (i.e. analogous to strcpy's return value).
Related QuestionsCan I drop the [] when deleteing array of some built-in type (char, int, etc)?
Freestore management, C++ FAQ LiteSometimes programmers think that the [] in the delete[] p only exists so the compiler will call the appropriate destructors for all elements in the array. Because of this reasoning, they assume that an array of some built-in type such as char or int can be deleted without the []. E.g., they assume the following is valid code: But the above code is wrong, and it can cause a disaster at runtime.
Related QuestionsHow can I convert an INT into CHAR*/STRING or vice versa?
Beginner FAQ - GPWikiThis is something you do a lot in programming and pretty much every language makes it easy to convert between types. You may have already printed integers to the console with COUT or PRINTF, which of course needs to be converted to a string first. Converting numbers to strings is done in a similar way. Boost is a C++ library that can help you with problems like these and many others.
Related QuestionsWhat standard types does C# use?
Andy Mc's C# FAQ for C++ programmersC# supports a very similar range of basic types to C++, including int, long, float, double, char, string, arrays, structs and classes. However, don't assume too much. The names may be familiar, but many of the details are different. For example, a long is 64 bits in C#, whereas in C++ the size of a long depends on the platform (typically 32 bits on a 32-bit platform, 64 bits on a 64-bit platform). Also classes and structs are almost the same in C++ - this is not true for C#.

FAQA lentiviral vector contains the genetic elements that enable a copy of it to be packaged into a viral particle when it is present in a cell line that expresses the other viral particle components, such as the coat proteins (i.e., a "packaging" cell line). For example, a lentiviral vector contains the critical portions of the "long terminal repeat" (LTR) sequences, which are necessary to express the packaged portion of the vector. Standard vectors cannot be packaged into viral particles.
