RE: [Dev-C++] Why does this work???

[Ioannis V. <no...@ho...>]

The code is not portable. It doesn't compile in C++ mode:
 
temp.cpp: In function `int main()':
temp.cpp:4: `strcmp' undeclared (first use this function)
temp.cpp:4: (Each undeclared identifier is reported only once for each
function 
   it appears in.)
temp.cpp:4: warning: unused variable `int i'
> Execution finished.

Subject: [Dev-C++] Why does this work???


Hi all,
In the two books I have, it says that in order to use the C-Style
function strcmp, I need to #include <string.h>. I tried the following in
compilers including DevC++ and it works.......?
//no includes.....
int main()
{
    char a[] = "Hello";
   int i = strcmp(a, "There");
    return 0;
}
 
To better show you, I didn't use any #include. Anyone has any idea as to
why this program compiles? If iostream.h is added and if you cout<<i
then it shows the returned value.
 
Thanks for your feedback.
