(can't be modified). In such case, we may need to use STL, but so such header file is included in the given code for STL. In such case, it might seem that, we can't use STL here & we need to take any other way, which is not at all efficient. If you think so, wait a ...
Re: STL <list> declaration in header file Thanks for your fast answer and excuse my uncomplete post! Here are all three files of the testing program, line 29 is marked: test.h --- /* */ #ifndef TEST_HEADER #define TEST_HEADER class xy { public: void getI(void); void setI(int)...
Users who require library facilities for complex arithmetic but want to maintain compatibility with older compilers may use the compatibility complex numbers library whose types are defined in the non-standard header file <complex.h>. Although the header files <complex> and <complex.h> are similar...

File (/Yu) option, the compiler ignores all preprocessor directives (including pragmas) that appear in the source code that will be precompiled. The compilation specified by such preprocessor directives must be the same as the compilation used for the Create Precompiled Header File (/Yc) option....
For instance, the _toupper macro is defined in the header file CTYPE.H, while the function toupper is declared in STDLIB.H. Predefined Constant Many library routines refer to constants that are defined in header files. For instance, the _open routine uses constants such as _O_CREAT, which ...

The standard does not specify which STL header files will be included by which other STL headers. So if you forget to include STL headers explicitly required by your code, it may work because the dependency is brought in via some other header file you included. However, any change / removal...
