The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.
For these reasons, for C++ code to call a C function foo(), the C++ code must prototype foo() with extern "C". Likewise, for C code to call a C++ function bar(), the C++ code for bar() must be declared with extern "C". A common practice for header files to maintain both C and C++ compatibility is to make its declaration be extern "C" for the ...
Visual Studio Code, commonly referred to as VS Code, [9] is an integrated development environment developed by Microsoft for Windows, Linux, macOS and web browsers. [ 10 ] [ 11 ] Features include support for debugging , syntax highlighting , intelligent code completion , snippets , code refactoring , and embedded version control with Git .
The parse tree is also more suitable for supporting automated code refactoring, as it directly represents the original source code. Clang compiles only C-like languages, such as C, C++, Objective-C, and Objective-C++. In many cases, Clang can replace GCC as needed, with no other effects on the toolchain as a whole.
For the purposes of these tables, a, b, and c represent valid values (literals, values from variables, or return value), object names, or lvalues, as appropriate.R, S and T stand for any type(s), and K for a class type or enumerated type.
C is a fairly small language, with only a handful of statements, and without too many features that generate extensive target code – it is comprehensible. C has direct control over memory allocation and deallocation, which gives reasonable efficiency and predictable timing to memory-handling operations, without any concerns for sporadic stop ...

Most C code can easily be made to compile correctly in C++ but there are a few differences that cause some valid C code to be invalid or behave differently in C++. For example, C allows implicit conversion from void * to other pointer types but C++ does not (for type safety reasons).
