由 梦想的初衷 提交于 2019-12-13 04:33:32
问题 Given a string and two characters, I want to find how many times the first character exists on the string, in what position it appears first and create a new string where the second character replaces the first every time it shows up, but I'm having problems with the last part. This is what I have so far: #include <stdio.h> #include <string.h> #include <stdlib.h> main () { char string[10], string1; char c1, c2; int contador, i, l, n, contador2; printf ("Introduza uma string e dois caracteres.

Converting lower & upper case ASCII characters

由 别等时光非礼了梦想. 提交于 2019-12-13 04:32:37
问题 I'm making a program that converts ascii characters 'a' through 'z' and 'A' through 'Z'. (only letters). for example, a+1 = b a+2 = c b+1 = c A+1 = B So the only thing I'm not sure how to do is mapping around. How can I make it so that when checklower/checkupper is true, to basically map around to the lower case letter (example, of z+2 = b). 回答1: The simplest way is probably to use the % modulus operator: int letter_add = ((input.at(i) - 'a' + cmd_int) % 26) + 'a'; You'll need a symmetrical

Chunking English words into graphemes corresponding to distinct sounds

由 旧时模样 提交于 2019-12-13 02:46:53
问题 How to convert english input word into combinations of graphemes? Is there a library or function that does the job? What I'm looking for is an algorithm/implementation that splits orthographic words into segments which map to phonemes. That is, the sequence of letters in a word should be broken in between distinct sounds. To my mind, this would look something like the following: physically --> ph-y-s-i-c-a-ll-y psychology --> ps-y-ch-o-l-o-g-y thrush --> th-r-u-sh bought --> b-ough-t chew -->

PowerShell get-childitem cannot handle filename starting with [ character even with escape character

由 点点圈 提交于 2019-12-13 00:12:45
问题 I have a file in c:\temp directory named as [default].xml. When I issue command: get-childitem "c:\temp`[default].xml" in the powershell console, it returns me nothing. However if I issue this command: get-childitem "c:\temp*default].xml", it works as expected. Why escape character on '[' is not working? 回答1: See get-help about_wildcards The [] are wildcard "globbing" operators. To use get-childitem on files that have those characters, use the -literalpath switch to disable wildcarding of the

ANSI SQL 92: find last occurrence of character

问题 I need a ANSI SQL 92 statement to change all characters following the last '/' character to lower case. On Sybase I would write: update table set col = left(col, len(col)-charindex('/', reverse(col))) || lower(right(col, charindex('/', reverse(col)))) I can find all functions in ANSI SQL 92 but the REVERSE function, that I just use to find the last occurrence of the slash. 来源： https://stackoverflow.com/questions/7241090/ansi-sql-92-find-last-occurrence-of-character

问题 I'm trying to clean up a .CSV file in Excel by getting rid of any non-standard characters. The only characters I care about keeping are A-Z, 0-9, and a few standard punctuation marks. Any other characters, I'd like to delete. I've gotten the following macro to delete an entire row when it finds a cell which contains any characters I haven't specified, but I'm not sure how to get it to actually delete the character itself.
