There are a very large number of legal C programs which cannot be compiled as C++. There are C and C++ programs which will operate differently, depending upon whether you are compiling as C or C++. Trivial examples: /* Perfectly legal C, but not legal C++ */ /* Hint: just changing the variable names to non C++ keywords is not enough to fix this program to make it legal C++ */ #include <stdlib.h> int main(void) { int *new = malloc(5); int delete = 0; return delete; } /* Legal in C and C++, but answers are different: */ #include <stdio.h> int main(void) { printf("sizeof the letter 'a' is %d\n", sizeof('a')); return 0; } >You will be able to write your chess program in C, compile it with a C++ >compiler, and get exactly the same performance. > >If you use C++ features, your performance will decrease depending on which >features you use and how often you use them.
