For the superfastcode C++ project, open the module.cpp file in the code editor. In the module.cpp file, paste the following code: C++ Copy #include <Windows.h> #include <cmath> const double e = 2.7182818284590452353602874713527; double sinh_impl(double x) { return (1 - pow(e, (-2 ...
print(double(1) + 3) # will print 5 函数可以有很多参数,也可以一个参数都没有。 但是调用函数时需要提供的参数需要与定义函数时要求的参数数量相同。 def f(x, y, z): return x + y + z print(f(1, 3, 2)) # returns 6 ...
