Hello all,
Given below is the C++ program and the C-Build (compiler o/p) for the same.
Loop.cpp
--------
#include<iostream.h>
int main() {
return 0;
}
C-Build Output:
--------------
make -k all
gcc -g -c loop.cpp
In file included from /usr/include/c++/3.2.2/backward/iostream.h:31,
from loop.cpp:1:
/usr/include/c++/3.2.2/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 <X> header for the <X.h>
header for C++ includes, or <sstream> instead of the deprecated header
<strstream.h>. To disable this warning use -Wno-deprecated.

make: *** [loop] Error 1
make: Target `all' not remade because of errors.
------------------------------------------------------------ -------------------
Someone help me to come out this basic stuff..
Thanks in advance.

See your other thread, and btw. one thread should be enough for the same
problem! (C++-Project vs. C-Project)

^^^^^^^^^^^^
This form is deprecated (as the warning below says), and the
extensionless headers should be used now. For std-C headers like stdio.h
there is an extensionless equivalent with a 'c'-prefix, if you really
need C headers in C++.
#include <iostream>
and/or
#include <cstdio>
