   • What is the C++ equivalent of C language's scanf("%*c")?

     Top Answer

     Answered Jan 26, 2022 · 3 votes

     In C scanf("%[^\n]%*c"); would remove all the redundant characters like spaces, newline, alphaNumerics form the buffer before/ after taking another input.

     This is amiss in so many ways.

     • "%[^\n]%*c" scans 1 or more non- '\n' (Attempting to save them) and then 1 '\n' . There must exist a leading non- '\n' else the scanning stops. There is nothing special about spaces and alphanumeric - just '\n' and non- '\n' .
     • Undefined behavior: "%[^\n]" lacks a matching pointer to save the input. Even with a matching char * , it lacks a width and is prone to buffer overflow. It is worse than gets().
     • With an input of only "\n" , nothing is consumed, nothing is saved. scanf("%[^\n]%*c"); fails to consume anything if the first character is a '\n' . Without checking the return value, the calling code does not know if anything was read. The matching char * , if it was there, is unchanged or potentially indeterminate.

     Do not use scanf("%[^\n]%*c"); or its C++ equivalent std::scanf("%[^\n]%*c");

     OP's update to scanf("%d%*[^\n]%*c", &num); is still faulty and should not be used in robust code.

     • It risks undefined behavior due to int overflow. It does not check the return value.
     • It does not consume the rest of the line when the numeric text is followed by a '\n' . That '\n' remains in stdin .

     A better C approach begins with fgets() and checking return values.

   • What is IDE of C Language?

     Top Answer

     Answered Mar 14, 2021 · 2 votes

     You need a C compiler to compile and link your C code to a native executable. But that is all you need.

     In this respect1, the difference between C and Java is that the Java compilers compile to bytecodes, not to native code. Bytecodes are not directly executable. To execute the bytecodes you need either a JDK or a JRE2. (It is also possible to generate an executable from Java bytecodes using jlink for example, but that has an embedded JRE.)

     The java executable provided by a standard JRE or JDK starts and runs a Java virtual machine (JVM). The functionality of a JVM typicallly includes:

     • a bytecode loader and verifier,
     • a bytecode interpreter, and
     • a Just-in-time (JIT) compiler that compiles bytecodes to platform native code ... as required.

     This (e.g. the java command) is implemented as a native application. Existing implementations are coded in C and C++, but that is not an absolute requirement.

     You don't absolutely require an IDE for either C or Java. Both can be developed using a simple text editor, and compiled from the command prompt. An IDE is "nice to have" ...

     1 - There are of course many other differences. 2 - JRE and JDK are names for the two different kinds of Java distribution. A JRE consists of the tools and libraries for running Java applications. A JRE adds development tools; e.g. compilers, packagers, debuggers and so on. (But not an IDE.)

   • What is stdin in C language?

     Top Answer

     Answered Jun 09, 2016 · 7 votes

     No, stdin is not "a memory address".

     It's an I/O stream, basically an operating-system level abstraction that allows data to be read (or written, in the case of stdout).

     You need to use the proper stream-oriented I/O functions to read from the stream.

     Of course you can read from RAM too, so it's best to write your own function to require a function that reads a character, then you can adapt that function to either read from RAM or from stdin.

     Something like:

     int my_scanf(int (*getchar_callback)(void *state), void *state, const char *fmt, ...);-

     Is usually reasonable. The state pointer is some user-defined state that is required by the getchar_callback() function, and passed to it by my_scanf().

   • what is (*this) in c language?

     Top Answer

     Answered Oct 04, 2015 · 4 votes

     In C, this is a normal parameter name, no different from any other name.

     You're probably using a C++ compiler, where this is a keyword and will give an error when used as a parameter.
