Can anyone > give a suggestion? C code is usually either valid C++ code or is trivially modifiable to be valid C++ code. Whether such code runs faster when compiled as C or as C++ depends upon the quality of the compiler, not the language. However: C++ has additional features over C. Whether those features make the program faster or slower depends upon how you use them. No language feature is inherently "slow". Even if a particular feature has a performance cost, if it simplifies development then the time saved can be spent optimising other parts of the code. The question isn't which language you would use if you wanted absolutely optimal code (otherwise, everyone would use assembler). The question is which language will produce the best result given the development time available. The answer to that question depends more upon the skill of the programmers than on the language. On one hand, C++ has features which will allow a good programmer to both improve performance and reduce development time simultaneously. On the other hand, not all programmers are good programmers, and C++ provides not-so-good programmers with far greater scope for messing up.
