data input. scanf will automatically process the data according to the input format. You can use % f (normal mode), % e/% E (exponential mode), or % g/% G (automatically selected) for output ). 10. Floating Point parameter pressure stack rules: float (4 bytes) type extended to double (8 bytes) into the stack. Therefore, float (% f) and double (% lf) must be distinguished during input, while % f can be used for output. The printf function outputs the float (extended to double) and double data pu

This article mainly introduces how to use Python to determine the type of operating system code. it is often used to compile cross-platform programs. For more information, see cross-platform scripts, however, due to the differences between different platforms, we have to obtain the platform (operating system type) curr
