Execute C++ code snippets, directly on the command line.

$ instantcpp 'std::cout << "Hello World!" << std::endl;'
Hello World!

instantcpp gently grabs your naked C++ snippet, lovingly wraps it in a tiny warm blanket of cozy boilerplate code, compiles and executes the whole burrito, and then it even cleans up after itself. How nice! 💝

instantcpp [options] <code>

• --cxx=<value>, --cxx <value>: Use a custom compiler (instead of g++)
• --valgrind: Execute snippet in Valgrind
• --gdb: Execute snippet in GDB
• -c <value>: Add an option to compiler flags. Defaults are -W -Wall -Wextra -Wpedantic -std=c++11 -O0 (fairly many warnings, C++11, no optimization).
• -l <value>: Add an option to linker flags. None by default.
• -i <value>: Add another #include to the wrapper code. See code for defaults.
