Many embedded projects still use older (and outdated) environments that don't allow developers to use a new C++ standard. This is a mistake. Not only do programmers miss out on the newly added features, but C++11 also fundamentally improved several aspects.<\/strong><\/p>\n

<\/p>\n

Since version 11, things have been happening again in the world of C++. While the further development of the standard was largely ignored by embedded developers for a long time, version 11 of C++ has given the programming language renewed momentum and a number of new features that are worth taking a closer look at.<\/p>\n

One example that is often used is the new null pointer \u2013 <\/strong>nullptr.<\/strong><\/p>\n

Example:<\/p>\n

void doSomething(char * pc) { cout << "char*" << endl; } void doSomething(int i) { cout << "int" << endl; }<\/pre>\n
Age Code:<\/p>\n
void testNullPtr(void) { doSomething(NULL);    doSomething(0); }<\/pre>\n
Both calls result in `doSomething(int i)`, even though the first version appears to have passed a pointer. The implicit type adjustments result in a conversion to an integer.<\/p>\n
A cast is required for the correct call:<\/p>\n
void testNullPtr(void) { doSomething(static_cast (NULL)); doSomething(0); }<\/pre>\n
It's different in C++ from version 11 onwards:<\/p>\n
void testNullPtr(void) { doSomething(nullptr); doSomething(0); }<\/pre>\n
The "real" null pointer now tells the compiler what to do.<\/p>\n
Elsewhere, greater emphasis was placed on safe programming. Type-safe enumerations (enums) and the new smart pointers are worth mentioning. The introduction of RValue references simplifies the handling of temporary objects.<\/p>\n
Many small improvements make the developer's daily work easier.<\/h4>\n
This includes the automatic for loop<\/strong> (called a foreach loop in other programming languages) as well as the automatic type detection of variables<\/strong>. This was further improved in version 14 (especially regarding templates). Incidentally, if you're still using an older compiler, that's a good reason to skip version 11 and go straight to C++14.<\/p>\n
Another noteworthy innovation is the Lambda functions<\/strong>, These functions operate flexibly and anonymously. They allow you to complete small tasks directly on-site without having to write an additional function. Furthermore, they are very useful when it comes to adjusting the parameters passed to function calls.<\/p>\n
In addition to the language extensions, the standard library was also improved and expanded. Among other things, it now includes, for the first time... Classes for multithreading<\/strong>.<\/p>\n
Even though many innovations of the C++ language are only of limited use for many embedded projects, the newer C++ versions bring so many improvements and simplifications to everyday development that switching is worthwhile.<\/p>\n
