Java can access derived instance methods faster than C++ can access derived virtual methods due to C++'s extra virtual-table look-up. However, non-virtual methods in C++ do not suffer from v-table performance bottlenecks, and thus exhibit performance similar to Java.
Since C++23, the C++ standard library can now be imported as a module, but must be imported in its entirety rather than importing specific packages of the library like in Java, with import std;, or optionally if requiring the C standard library in the global scope, with import std.compat;.
Syntactically, Pascal is much more ALGOL-like than C. English keywords are retained where C uses punctuation symbols – Pascal has and, or, and mod where C uses &&, ||, and % for example. However, C is more ALGOL-like than Pascal regarding (simple) declarations, retaining the type-name variable-name syntax. For example, C can accept ...

The way to use the page that note 42 refers to to describe that Java is faster than C in some cases is clearly cheat! The only one listed in that page that Java is faster than C is the 240 vs 260/250 fps one -- the Original C Code vs Jake2-0.9.4 JRE1.5 fastjogl/lwjgl. The speed of programs that using OpenGL is largely depended on OpenGL.
Java is explicit about extending classes and implementing interfaces, while C# infers this from the kind of types a new class/interface derives from. C# supports more features than Java, which to some extent is also evident in the syntax that specifies more keywords and more grammar rules than Java.
