Why does C# allow {} code blocks without a preceding statement?
...
And in C++, because of RAII instead of GC, it is far more useful.

How to repeat a string a variable number of times in C++?
... want to insert 'n' spaces (or any string) at the beginning of a string in C++. Is there any direct way to do this using either std::strings or char* strings?
...
Are typedef and #define the same in c?
...ound types (like structs and function pointers) readable and handlable (in C++ there are even situations where you must typedef a type).
For (3): You should always prefer language features over preprocessor macros when that's possible! So always use typedefs for types, and constant values for const...

Convert to absolute value in Objective-C
...re present both in Objective-C and plain C (and are generally available in C++ programs too.)
(Alas, there is no habs(short) function. Or scabs(signed char) for that matter...)
Apple's and GNU's Objective-C headers also include an ABS() macro which is type-agnostic. I don't recommend using ABS()...
Restore the state of std::cout after manipulating it
...
@ChrisJester-Young, actually good C++ is RAII, especially in a case like this one!

Why aren't variables declared in “try” in scope in “catch” or “finally”?
...
EDIT: I guess every rule does have an exception. The following is valid C++:
int f() { return 0; }
void main()
{
int y = 0;
if (int x = f())
{
cout << x;
}
else
{
cout << x;
}
}
The scope of x is the conditional, the then clause and th...
What is the canonical way to check for errors using the CUDA runtime API?
...ccasionally we may wish to report and recover from an error condition in a C++ context as part of a larger application.
Here's a reasonably terse way to do that by throwing a C++ exception derived from std::runtime_error using thrust::system_error:
#include <thrust/system_error.h>
#include &...
Why can't my program compile under Windows 7 in French? [closed]
.... African variants of French are out because they are too poor to afford a C++ compiler, however you could use C instead.
Then there are other syntax errors in your program:
You forgot to translate some keywords.
Beware that the compiler and the documentation don't always use the same translation...
How do you disable the unused variable warnings coming out of gcc in 3rd party code I do not wish to
...u need to use this function as a handler - which (imho) is quite common in C++ Boost library. Then you need the second formal parameter version, so the function's signature is the same as the template the handler requires, otherwise the compilation would fail. But you don't really need it in the fun...
