increment

问题 I am currently stuck with my RPS program in that it will not properly store the number of times the user loses, or ties with the computer. For instance, when I run the program and enter "q" to quit I get the following output: Enter R, P, S, or Q (for quit) q You won 0 times, while the computer beat you 1900022269 times. You both tied 3 times. Thank you for playing! Note that I have played several games instead of running and quitting and have also gotten bad values for "l" and "t". It seems

问题 I have a directory with 264420 files $ find /Users/Username -type f | wc -l 264420 I'm trying to count the file number recursively in Node.js with simple counter++ The issue is that counter++ gives incorrect number of files, while array.push(file) with array.length in the end working just fine and gives back correct amount of files - 264420 $ node total-files.js 114 'total_files_count' 264420 'total_files_array_count' The simplified script looks like the following: const fs = require('fs')

问题 Consider the following code, in C++: #include <cstdlib> std::size_t count(std::size_t n) { std::size_t i = 0; while (i < n) { asm volatile("": : :"memory"); ++i; } return i; } int main(int argc, char* argv[]) { return count(argc > 1 ? std::atoll(argv[1]) : 1); } It is just a loop that is incrementing its value, and returns it at the end. The asm volatile prevents the loop from being optimized away. We compile it under g++ 8.1 and clang++ 5.0 with the arguments -Wall -Wextra -std=c++11 -g -O3

问题 i have a table with some rows. idClient, name, adress,country,... i want to know how i can do an insert into this table with auto increment my idClient in my sql request..?

问题 I am reading in data from an XML file. Due to an error at the source it is one day out, so after loading into the database I use this SQL statement to increment the date. UPDATE 2011_electricity SET DATE = DATE_ADD( DATE, INTERVAL 1 DAY ) Last week it worked fine, however now I get an error: MySQL said: #1062 - Duplicate entry '2011-07-20' for key 1 I have one primary key on the data field. This is how the database looks: date energy daynum 2011-06-29 0.05 4197 2011-07-19 0.20 4219 2011-07-20

问题 I am trying to use the Ruby Sequel gem for DB operations. I am stuck for incrementing and decrementing values. The doc says that this should work, even though it seems very strange for me to be able to add a number and a symbol. 2.0.0-p247 :019 > require 'sequel' => true 2.0.0-p247 :020 > s = Sequel.connect('sqlite://db.sqlite') => #<Sequel::SQLite::Database: "sqlite://db.sqlite"> 2.0.0-p247 :021 > s[:query_volume].update_sql(:queries => 3) => "UPDATE `query_volume` SET `queries` = 3" 2.0.0

问题 why is the variable "number" not increasing when the FOR loop goes over it again? setLocal EnableDelayedExpansion for /f "tokens=* delims= " %%a in (input.txt) do ( set /a N+=1 set /a number=!number!+1 echo %%a !number!.jpg >output.txt ) 回答1: OK, try this please: @echo off &setLocal EnableDelayedExpansion (for /f "tokens=* delims= " %%a in (input.txt) do ( set /a N+=1 set /a number=!number!+1 echo %%a !number!.jpg ))>output.txt In case of redirection you need >>output.txt or a code block

问题 what is wrong with this code? $core->query("UPDATE games SET hits = hits + 1 WHERE id=".intval($id).";"); hits incerements by 2 and sometimes by 3! I mean for example hits = 3; when I call this function, hits will be 5 and sometimes 6! (add 2 and 3 instead 1). mysql table type is MyISAM. query function is: function query($query) { $this->error=""; $this->result=@$this->link->query($query); if(!$this->result) { $this->error=@$this->link->error; return FALSE; } return $this->result; } link is:
