That subset could be compiled with both of those C and C++ compilers, and when compiled as C++ is better style checked than “pure C.”
Comparing the overall performance of a set-sized array allotted over the stack from a vector with its features over the free retail outlet is bogus.
: a sort that behaves around like an built-in sort like int, but perhaps without having a == operator. See also common type
p can be a Shared_ptr, but very little about its sharedness is used listed here and passing it by value is usually a silent pessimization;
Regular styles for example vector could be modified to perform bounds-checks under the bounds profile (in a suitable way, for example by including contracts), or used with at().
