spaces

问题 See this main : int main(void) { int i; int ch; char str[512]; fgets(str, sizeof str, stdin); for (i = 0; i <= (strlen(str)); i++) { if (str[i] != '\0' && str[i] != '\n') { int num = atoi(&str[i]); printf("%d\n", num); } } return 0; } I want to get line with numbers from user and get all the numbers without any spaces or tabs . For example: The input 1 2 3 . But in this case this the output: 1 2 2 3 3 So why i received 2 and 3 twice? 回答1: Here's how I would do it: char line[256]; if (fgets

问题 Somebody came up with the brilliant idea of putting spaces in a filename. I need to do scp from python using that filename, which is problematic because the shell parses the command, and scp has also some quircks regarding spaces. This is my test code: import subprocess import shlex def split_it(command): return shlex.split(command) #return command.split(" ") def upload_file(localfile, host, mypath): command = split_it('scp {} {}:"{}"'.format(localfile, host, mypath)) print(command) res =

问题 Downloaded Qt and Qt Creator. In Qt Creator I can run example programs. Created new project - Qt empty project. Added new cpp-file with code example from Qt site - first one.

问题 I need to write a regular expression for taking input like this 23,456,22,1,32767 i.e. No commas allowed at the start or end. Spaces may come before and/or start of comma for e.g. 23, 45,56 ,67 etc. Ranges of each number should be 0-32767. Currently I am using regular expression like this [0-9]+(,[0-9]+)* . This allows for numbers separated by commas only ( not allowing spaces at all), and it does not check for the range of number. 回答1: It's probably wise to do it in two steps. First check

问题 Using python and argparse, the user could input a file name with -d as the flag. parser.add_argument("-d", "--dmp", default=None) However, this failed when the path included spaces. E.g. -d C:\SMTHNG\Name with spaces\MORE\file.csv NOTE: the spaces would cause an error (flag only takes in 'C:SMTHNG\Name' as input). error: unrecognized arguments: with spaces\MORE\file.csv Took me longer than it should have to find the solution to this problem... (did not find a Q&A for it so I'm making my own
