Which is

问题 I'm trying to convert a char * to uppercase in c, but the function toupper() doesn't work here.

问题 I have a large file where each line contains space-separated integers. The task is to sparse this file line-by-line. For the string to int conversion I have three solutions: static int stringToIntV1(const string& str) { return (atoi(str.c_str())); } However, if I pass a malformed string, it doesn't produce any error. For instance the string "123error" is converted to 123. Second solution: static int stringToIntV2(const string& str) { int result; istringstream myStream(str); if (myStream >>

How can I speed this loop up? Is there a class for replacing multiple terms at at time?

问题 The loop: var pattern = _dict[key]; string before; do { before = pattern; foreach (var pair in _dict) if (key != pair.Key) pattern = pattern.Replace(string.Concat("{", pair.Key, "}"), string.Concat("(", pair.Value, ")")); } while (pattern != before); return pattern; It just does a repeated find-and-replace on a bunch of keys. The dictionary is just <string,string> . I can see 2 improvements to this. Every time we do pattern.Replace it searches from the beginning of the string again. It would

问题 Is there an easy way to convert a string from csv format into a string[] or list? I can guarantee that there are no commas in the data. 回答1: string[] splitString = origString.Split(','); (Following comment not added by original answerer) Please keep in mind that this answer addresses the SPECIFIC case where there are guaranteed to be NO commas in the data. 回答2: String.Split is just not going to cut it, but a Regex.Split may - Try this one: using System.Text.RegularExpressions; string[] line;

Python convert a str to path type?

偶尔善良 提交于 2020-01-22 18:03:33
问题 I am trying to interface with some existing code that saves a configuration, and expects a file path that is of type 'path.path'. The code is expecting that the file path is returned from a pygtk browser window (via another function). I want to call the save_config function elsewhere in my code with a file path based on different inputs, constructed from string elements. When I try to run the code, I am able to construct the file path correctly, but it is a string type, and the save function

I know that Java can't handle this: Integer.parseInt("0x64") Instead you have to do this: Integer.parseInt("64", 16) Is there something built into Java that can automatically parse integer strings for me using the standard prefixes for hex, octal, and lack of prefix for decimal (so that I don't have to strip off the prefix and explicitly set the base)? 回答1:
