C is faster than c++
WebBoth can be combined on today’s modern SIMD CPUs with multiple cores. In theory, either of these should be faster than single-thread serial calculation. In practice, however, there is a certain amount of overhead involved in setting up either kind of parallelism. WebOf course, C# (or Java, or VB) is usually faster to produce viable and robust solution than is C++ (if only because C++ has complex semantics, and C++ standard library, while interesting and powerful, is quite poor when compared with the full scope of the standard library from .NET or Java), so usually, the difference between C++ and .NET or Java …
