I was working on C++ and encountered following error

"Fatal iostream.h 19: Error directive : Must use C++ for the type iostream"

can anyone tell me what does this mean!

Supposedly that you tried to compile the program with a C compiler (or linker) rather than a C++ one. That's just a guess, though.

no i'm using c++ compiler..

What header files did you include? Did you do something bad like #include <iostream.h> rather than <iostream> ?

i did <iostream>not #include<iostream.h>

i used <stdlib>, <process> amongst others

OK then. A couple other possibilities:

 

Did you name your file "myprogram.c" rather than "myprogram.cc" (or "myprogram.cpp" or "myprogram.c++")? Some compilers know that .c files are to be compiled as if they are written in C rather than C++.

 

Do you have an unterminated extern "C" { (i.e., missing close brace) lurking around somewhere, including in the headers files you #included before the #include <iostream> directive?

no such error done by me.

Do you have #include before <iostream>? Because that wasn't very obvious from your post...

Thanks all for the suggestions but the problem was with the compiler..i changed it and now its working..
