Try #include . –Null Nov 26 '14 at 20:36 2 iostream is a C++ header, not C... and for printf you need stdio.h. –Dmitri Nov 26 '14 at 20:38 @Dmitri It's iostream.h which is indicative of a Turbo C/C++ compiler. –user3920237 Nov 26 '14 at 20:47 @remyabel i stored the program in c extension. –arunwebber Nov 26 '14 at 20:48 1 void main() is illegal in C++ and undefined behavior in C. –Keith Thompson Nov 26 '14 at 21:28 | show 3 more comments 1 Answer 1 act

Matthias Blaickner To: cygwin at cygwin dot com Date: Thu, 7 Dec 2006 05:01:54 -0800 (PST) Subject: iostream Hi everybody I have https://cygwin.com/ml/cygwin/2006-12/msg00283.html problems with cygwin supporting iostream.h I use g++ as compiler and I'm https://bytes.com/topic/c/answers/141001-iostream-under-cygwin told to remove the .h suffix from the header. doing so results in error messages about unknown functions. the test programm is: #include main() { cout << "He's not the Messiah. He's a very naughty boy" << endl; } resulting in: In file included from no such /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/backward/iostream.h:31, from test.cc:1: /usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the header for the header for C++ includes, or instead of the deprecated header . To disable this warning use -Wno-deprecated. no such file test.cc:5:2: warning: no newline at end of file using returns: test.cc: In function `int main()': test.cc:4: error: `cout' undeclared (first use this function) test.cc:4: error: (Each undeclared identifier is reported only once for each function it appears in.) test.cc:4: error: `endl' undeclared (first use this function) test.cc:5:2: warning: no newline at end of file I really searched the mailing list, the web etc. the advice below doesn't help me since I Do use g++ and a cc-suffix. thanks for any advise matthias I believe this is in the gcc FAQ.

I am trying to insure that I have a reasonable development environment, and that things are working properly, by trying to compile and run the following classic program. $ cat hellow.cpp #include int main (int argc, char *argv[]) { cout << "Hello, world" << endl; } However, when I try to compile, I get $ g++ hellow.cpp hellow.cpp: In function `int main(int, char**)': hellow.cpp:4: error: `cout' undeclared (first use this function) hellow.cpp:4: error: (Each undeclared identifier is reported only once for each function it appears in.) hellow.cpp:4: error: `endl' undeclared (first use this function) In trying to get more comprehensive infomation, I tried the command shown below with its output. If I'm doing something pathetically stupid, do not hesitate to tell me so --- I've been doing Java for a few years, and I may have forgotten something really important. :-) Thanks in advance for any help. - Jerry Oberle $ g++ -v -H hellow.cpp Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/specs Configured with: /gcc/gcc-3.3.3-3/configure --verbose --prefix=/usr --exec-prefi x=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/s hare/man --infodir=/usr/share/info --enable-languages=c,ada,c++,d,f77,java,objc, pascal --enable-nls --without-included-gettext --enable-libgcj --with-system-zli b --enable-interpreter --enable-threads=posix --enable-java-gc=boehm --enable-sj lj-exceptions --disable-version-specific-runtime-libs --disable-win32-registry Thread model: posix gcc version 3.3.3 (cygwin special) /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/cc1plus.exe -quiet -v -D__GNUC__=3 -D__GN UC_MINOR__=3 -D__GNUC_PATCHLEVEL__=3 -H -D__CYGWIN32__ -D__CYGWIN__ -Dunix -D__u nix__ -D__unix -idirafter /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/../../../../incl ude/w32api -idirafter /usr/l
