Question

Using the iostream, fstream, vector and string headings in C++, can sombody show me a sample code for reading in a file name, opening that file, and then read in every word from the file and store them in a vector of strings and print out the size of the vector aka the total number of words in the story?

Answer 1

main.cpp

#include<iostream>
#include<fstream>
#include<vector>
using namespace std;
int main()
{
string s; //string for storing file name
vector<string> v; //for storing words in the file
cout<<"Enter file name: "; //prompting user to enter file name
cin>>s; //user entering file name
ifstream in(s); //opening the file entered by the user
while(!in.eof()) //reading file till we eof(end of file)
{
string temp; //for storing a word in file
in>>temp; //reading a word from file
v.push_back(s); //pushing that word in the vector
}
in.close(); //closing the file
cout<<v.size(); //displaying the number of words
return 0;
}
