  Faster than C

Judging the performance of programming languages,usually C is called the leader,though Fortran is often faster.New programming languages commonly use C as their referenceand they are really proud to be only so much slower than C.Few language designer try to beat C.What does it take for a language to be faster than C?Better Aliasing InformationAliasing describes the fact that two references might point to the same memory location.For example, consider the canonical memory copy:void* memcopy(void* dst, const void* src, size_t count) { while (count--) *dst++ = *src++; return dst;}Depending on...

  The ugliest C feature:

<tgmath.h> is a header provided by the standard C library,introduced in C99 to allow easier porting of Fortran numerical software to C.Fortran, unlike C, provides “intrinsic functions”, which are a part of the language and behave more likeoperators. While ordinary (“external”) functions behave similarly to C functions with respect to types(the types of arguments and parameters must match and the restult type is fixed), intrinsic functions accept arguments of several types and their return type may depend on the type of their arguments.For example Fortran 77 provid...
