C++ str.find(str2) seems to be not working



right now I'm working on a program but I've run into this issue. Disclaimer; I'm not that experienced with c++ yet.
For my program I'm taking a user input, and comparing a string to that. If the userinput contains, key word here, contains. Doesn't have to equal but contain, the program should return a string. Now I've looked up this issue on the Web and the best way to do this seems by using str.find(str2) now as I understand by reading it, str2 should be the substring looked for in str, but I can't get that to work. So I reversed them str2.find(str). But this only gives of a result if the string is exactly equal. Am I doing anything wrong in my setup maby?


str.find(str2)


str2.find(str)


#include <iostream>
#include <string>

using namespace std;
int main()

string Userinput;
string str2 = "He";
cin >> Userinput;
std::size_t found = str2.find(Userinput);
if (found!=std::string::npos)

std::cout << "found it!" << str2 << 'n';

return 0



I'm looking for any help! Thanks in advance!



I'm sorry for the typos, I'm typing on my phone, I'll check again but I think I fixed them but when my input is He, it says found. When my input is Hello it returns nothing





Your description mentions str and str2, while your code uses str2, userinput, and afk. Can you make them match so it makes sense? You might also read through Minimal, Complete, and Verifiable example and fix your example so it shows the values of the variables you're using and how you're using them.

Show how you read user input. Is there a newline on the end?

Your code is still not complete. Also, what input do you use?

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]&g
