delimiter

问题 Goal: Take string 'One Two Three' which is stored in EDI and call strtok. strtok should split the string so that ESI points to the rest of the string after some delimiter and the first part of the string before the delimiter is stored in a register. After Call strtok with the delimiter of ' ' the result should be ESI = 'Two Three' and some other register = 'One' Using the code below i can find the index of the first instance of a space ' ' in string stored at EDI. index at the end is stored

问题 Is there any way in Java to use a special delimiter at the start and the end of a String to avoid having to backslash all of the quotes within that String? i.e. not have to do this: String s = "Quote marks like this \" are just the best, here are a few more \" \" \"" 回答1: No, there is no such option. Sorry. 回答2: No - there's nothing like C#'s verbatim string literals or Groovy's slashy strings, for example. On the other hand, it's the kind of feature which may be included in the future. It's

问题 I have some text (meaningful text or arithmetical expression) and I want to split it into words. If I had a single delimiter, I'd use: std::stringstream stringStream(inputString); std::string word; while(std::getline(stringStream, word, delimiter)) { wordVector.push_back(word); } How can I break the string into tokens with several delimiters? 回答1: Assuming one of the delimiters is newline, the following reads the line and further splits it by the delimiters. For this example I've chosen the

问题 I have a dataframe as below. I want to split the last column into 2. Splitting needs to be done based upon the only first : and rest of the columns dont matter. In the new dataframe, there will be 4 columns. 3 rd column will be (a,b,d) while 4th column will be (1,2:3,3:4:4) any suggestions? 4th line of my code doesnt work :(. I am okay with completely new solution or corrections to the line 4 employee <- c('John Doe','Peter Gynn','Jolie Hope') salary <- c(3, 2, 1) df <- data.frame(employee,

问题 How would I read comma delimited doubles with no white space? I tried the following: fscanf(file, "%lf[^,], &x) but it doesn't work. The file will be in the following format: 1.0,2.0,4.0 3.0,6.0,1.0 回答1: Instead of using [^,] regular expression you directly use , . #include <stdio.h> int main(){ FILE *fp; double buff[255]; int i=0; fp = fopen("file.txt", "r"); while(fscanf(fp, "%lf,",&buff[i++])!=EOF){ printf("%0.1lf ", buff[i-1] ); } fclose(fp); } 来源： https://stackoverflow.com/questions

问题 I am hoping that someone will be able to help me out, basically I have a text file that I need to split based on a variable that will be contained within the file….. I have added below an example of how the source file would look… What I need to do is ignore the header and footer and then split the file in to separate files based on the second delimiter so for the first row this would be “1001” the files should group all of the matching references into the file and then apply a header and

问题 I'm looking for a way to split string by multiple delimiters using regex in C++ but without losing the delimiters in output, keeping the delimiters with splitted parts in order, for example: Input aaa,bbb.ccc,ddd-eee; Output aaa , bbb . ccc , ddd - eee ; I've found some solutions for this but all in C# or java, looking for some C++ solution, preferably without using Boost. 回答1: You could build your solution on top of the example for regex_iterator. If, for example, you know your delimiters
