help, gcc, ?cout error?

[Tom Barron]

Hi, Jesse.  I pasted your code into a file called jesse.cpp on my
system.  Watch this:

$ gcc jesse.cpp
/tmp/ccyMXXQa.o: In function `main':
/tmp/ccyMXXQa.o(.text+0x25): undefined reference to `cout'
/tmp/ccyMXXQa.o(.text+0x2a): undefined reference to
`ostream::operator<<(int)'
collect2: ld returned 1 exit status
$ g++ jesse.cpp
$ a.out
5$ 

The problem is that cout and iostream.h are part of C++, but gcc only
handles C.  To compile C++ code, you need to invoke the compiler as g++.

To get a newline on the end of your output, you might want to do

     cout << a << endl;

hth...
