c++ - . c vs . cc vs. . cpp vs . hpp vs . h vs . cxx - Stack Overflow Historically, the first extensions used for C++ were c and h, exactly like for C This caused practical problems, especially the c which didn't allow build systems to easily differentiate C++ and C files Unix, on which C++ has been developed, has case sensitive file systems So some used C for C++ files
Difference between and in C? - Stack Overflow In early C, the operator did not exist, and because of that was used for this purpose One way to explain it is that you could imagine that is the same thing as applying on each individual bit in the operands Also note that has lower precedence than , even though intuition says that it should be the other way around
C++ code file extension? What is the difference between . cc and . cpp Note the C - case matters in GCC, c is a C file whereas C is a C++ file (if you let the compiler decide what it is compiling that is) GCC also supports other suffixes to indicate special handling, for example a ii file will be compiled as C++, but not pre-processed (intended for separately pre-processed code)
The Definitive C Book Guide and List - Stack Overflow Books that are deemed satisfactory by the C community here will stick around on the list; the rest will be regularly removed For books that have reviews by the Association of C and C++ Users (ACCU), a link to those reviews should be added along with the book See also: Other C-related resources in the c tag wiki
c - What do 0LL or 0x0UL mean? - Stack Overflow These are constants in C and C++ The suffix LL means the constant is of type long long, and UL means unsigned long In general, each L or l represents a long and each U or u represents an unsigned So, e g 1uLL means the constant 1 with type unsigned long long This also applies to floating point numbers:
c - What is the behavior of integer division? - Stack Overflow From the ANSI C draft (3 3 5): If either operand is negative, whether the result of the operator is the largest integer less than the algebraic quotient or the smallest integer greater than the algebraic quotient is implementation-defined, as is the sign of the result of the % operator
