问题 Is windows command line prompt similar to o/s interpreter? that mean o/s interpreter is command interpreter. command interpreter Is cmd also the interface of the command interpreter? 回答1: Yes. OS/2 is the same as Win NT 4 CMD.exe. In Windows 2000 it was upgraded and this is the current feature version. All references in help to new behaviour is the differences between OS/2-NT4 and Windows 2000. CMD.exe was written by a IBM engineer. She added scripting features common on IBM mainframes to the

问题 What are the relative strenghts and weaknesses of compiled and interpreted languages? Why? 回答1: Neither approach has a clear advantage over the other - if one approach was always better, chances are that we'd start using it everywhere! Generally speaking , compilers offer the following advantages: Because they can see all the code up-front, they can perform a number of analyses and optimizations when generating code that makes the final version of the code executed faster than just

问题 Yes, I use F12 in the browser all the time to test out Javascript snippets with the console. I'm tired of that (for the moment anyway). I've read that in Visual Studio you can use the immediate window to run Javascript interactively.. I've haven't tried it that hard. I think when I did it told me it can't evaluate while in design mode... ugh, what a pain. I do like to use Visual Studio Code (sublime text historically) sometimes to just mess around with syntax of snippets. Would also be nice

问题 I've a DLL that embeds Python interpreter using the C/Python API. The DLL works fine if called one time, but if the DLL is called twice, the code cracks and my program catch memory error. The C code calling DLL is simple and the call to DLL function(Which calls Python interpreter) is done one time, if the second call(In the code) is not commented the code cracks and this happens only if "Numpy" is called in the Python code. #include <stdio.h> #include <conio.h> #include <math.h> #include <dll

Why does Java have much better performance compared to other interpreted languages like Python? I know this probably has something to

问题 I'm writing an interpreter for a game. User enters its move to the interpreter and program executes that move. Now I want to implement a time limit for each decision. Player shouldn't be able to think more than 30 seconds to write a move and press enter. call_with_time_limit seemed relevant but it doesnt work properly as such: call_with_time_limit( 30, read(X) ), Problem, write(Problem). In this case, it waits for input, and when input is entered, timer starts afterwards. But I want the timer

问题 I just downloaded GNU emacs23.4, and I already have python3.2 installed in Windows7. I have been using Python IDLE to edit python files. The problem is that I can edit python files with Emacs but I do not know how to run python interpreter in Emacs. When i click on "switch to interpreter", then it says "Searching for program: no such file or directory, python" Someone says i need to make some change on .emacs file, but i do not know where to look for. And I am very unexperienced and just
