for(string s:x) does it exist?

[uperkurk]

I have a program that reads txt from a file and counts how many words there are. I need to modify it to count how how many occurences of a certain word there is, in Java I'd do something like:

for(string s:x){
//do something
}

How can I do something like this in C++? While the program is reading the file, I need it to add 1 everytime the next word is "SPECIAL".

I'm a bit stuck if I'm honest, don't really know what I should be reading.

a) Yes, if your compiler supports this feature of C++11. (MSVC 11+, GCC 4.6+)
b) No, if your compiler doesn't. (MSVC 10-, GCC 4.5-)

To count how many occurences of S are in X, the C++ solution is to call std::count(X.begin(), X.end(), S)

#include <iostream>
#include <string>
#include <fstream>
#include <iterator>
#include <algorithm>
int main()
{
    std::string word = "SPECIAL";

    std::ifstream file("test.txt");
    std::istream_iterator<std::string> beg(file), end;
    unsigned int cnt = count(beg, end, word);

    std::cout << "the word '" << word << "' found " << cnt << " times\n";
}

Although you can certainly do it the way you describe

#include <iostream>
#include <string>
#include <fstream>
int main()
{
    std::string word = "SPECIAL";
    
    std::ifstream file("test.txt");
    unsigned int cnt = 0;
    for(std::string s; file >> s; ) // While the program is reading the file
        if(s == word) //  everytime the next word is "SPECIAL".
            ++cnt;  // add 1
            
    std::cout << "the word '" << word << "' found " << cnt << " times\n";
}
