问题 Is there a way to format a real number for output such that both the width and decimal parts are left unspecified? This is possible with ifort by just doing the following: write (*, '(F)') num ...but I understand that that usage is a compiler-specific extension. Gfortran does accept the standard-compliant 0-width specifier, but I can't find anything in the standard nor in gfortran's documentation about how to leave the decimal part unspecified. The obvious guess is to just use 0 for that as

问题 I have this Program: #include <stdio.h> #include <string.h> #include <stdlib.h> void main(void) { char *buffer1 = malloc(sizeof(char)); char *buffer2 = malloc(sizeof(char)); strcpy(buffer2, "AA"); printf("before: buffer1 %s\n", buffer1); printf("before: buffer2 %s\n", buffer2); printf("address, buffer1 %p\n", &buffer1); printf("address, buffer2 %p\n", &buffer2); strcpy(buffer1, "BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB"); printf("after: buffer1 %s\n", buffer1); printf("after: buffer2 %s\n", buffer2)

问题 My cell output in Jupyter Notebook is cut off on the left hand side which obscures the leftmost output. For reference (I can't post images yet): https://imgur.com/gallery/rg759nN Any idea how to fix this? EDIT: Thanks to rabbit on below, the problem seems to be caused by using the alternate themes provided by Jupyter Themes 回答1: Found the solution on Jupyter Themes github page: https://github.com/dunovank/jupyter-themes/issues/288 "In the custom.css file, I fixed it by changing both the div

问题 I am attempting to read a .dat file using Java in TextPad. The .dat file has multiple lines of code but each line has separate pieces of information that I need for different methods in my main method and object classes. How do I separate the information provided in the file and input the separate pieces into any of my classes? I know how to read basic input from a .txt file but it is not working with the .dat file. I do not know how to separate data that does not have commas, and I am not

问题 We are writing a Xamarin.Mac application. We need to execute a command like "uptime" and read it's output into an application to parse. Could this be done? In Swift and Objective-C there is NTask, but I don't seem to be able to find any examples in C#. 回答1: Under Mono/Xamarin.Mac, you can the "standard" .Net/C# Process Class as the Process gets mapped to the underlaying OS (OS-X For Mono, MonoMac and Xamarin.Mac, and Mono for *nix). Process p = new Process(); p.StartInfo.UseShellExecute =

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . This is just a quick question. But I am trying to output data to a file, which works fine. However I am also trying to implement a new line at the appropriate point so the data, prints on individual lines. This

问题 I have an array of this weeks, next weeks and the week after's dates holding the date, an opening time and a closing time. For some reason, when the foreach loop reaches the final date, it outputs the array of the final week instead of the final date. Here is the start of the array: $dates = Array ( [0] => Array ( [0] => Array ( [0] => "Mon 23rd June" [1] => "9:00am" [2] => "7:00pm" ) [1] => Array ( [0] => "Tue 24th June" [1] => "9:00am" [2] => "7:00pm" ) ... [1] => Array ( [0] => Array ( [0]

问题 How do you prevent output in the CMD window? I know how to do it for these @echo off timeout /t 3 /nobreak >nul MKDIR Files 2>nul But I was wondering what the general way is for all commands, or how to find out for each command that way I don't have to keep asking. I'm trying to get XCopy to copy silently, that way the screen doesn't get spammed, but I have a feeling I'll need it for other commands too. 回答1: There are 2 output streams: stdout (standard output console) and stderr (standard

问题 In Python, variables have truthy values based on their content. For example: >>> def a(x): ... if x: ... print (True) ... >>> a('') >>> a(0) >>> a('a') True >>> >>> a([]) >>> a([1]) True >>> a([None]) True >>> a([0]) True I also know I can print the truthy value of a comparison without the if operator at all: >>> print (1==1) True >>> print (1<5) True >>> print (5<1) False But how can I print the True / False value of a variable? Currently, I'm doing this: print (not not a) but that looks a
