WebA C++ compiler supporting at least C++11 is required. Compilation can be done by directly including uint128_t.cpp in your compile command, e.g. g++ -std=c++11 main.cpp uint128_t.cpp, or other ways, such as linking the uint128_t.o file, or creating a library, and linking the library in. WebMar 8, 2012 · Add a comment. 5. How to specify 64 bit integers in c. Going against the usual good idea to appending LL. Appending LL to a integer constant will insure the type is at least as wide as long long. If the integer constant is octal or hex, the constant will become unsigned long long if needed. If ones does not care to specify too wide a type, then ...
