How can I load a txt file into a hashing table in C++?

include <iostream>

#include <string>

#include <fstream>

#include <map>

using std::cout;

using std::string;

using std::ifstream;

using std::map;

int main()

{

map<int, string> table;

int t = 0;

string s;

ifstream file("filename.txt");

while(file >> t && getline(file, s))

table[t] = s;

map<int, string>::const_iterator iter = table.begin();

for(; iter != table.end(); ++iter)

cout << iter->first << iter->second << "\n";

}

Is not really a Hash table, a map is implemented using a red black tree, but if you have a hash table in your implementation, it can be almost the same

see unordered_map

the place is the txt document coming from? If that's from the server, then Adz is right, AJAX is a thank you to bypass - the document can in basic terms be served via way of the conventional webserver in keeping with an AJAX request. If that's on yet another server, you are able to run into the browser's go-website scripting risk-free practices. If the document is on the customer's close by gadget, it is not accessible. Javascript does not have get right of entry to to the close by filesystem, for risk-free practices motives.
