    Dev C++ and Strings

    I am using dev c++ and it doesnt like strings for me like:
    PHP Code:
    #include <string>

    ....


    string word;
    word "hi"
    I get alot of errors with code similar to that. Anyone else have these problems ?

    Code:
    #include <string>
    
    ....
    
    std::string word;
    word = "hi";
    If that doesn't work then post more code, preferably a complete compilable program that we can work with and figure out your problem in a way that is better than guessing.

    another option!!

    Code:
    #include <string>
    using namespace std;
    ....
    
    string word;
    word = "hi";

    or even....

    Code:
    #include <string>
    using std::string;
    ....
    
    string word;
    word = "hi";

    Although it's been a while since I've used Dev....there are a couple of things that I think might help your malaise...

    First, try using namespace std;...
    Second, append a '.h' to the end of your #include string file
    i.e. #include <string.h>

    This might help, hope it does.

    <<

    There is no need for using namespace std; if you have a .h at the end.

    May be some other mistakes. my compiler works fine with that code. my soft is also Dev-C++, version 4.9.3.0

    PHP Code:
    #include <iostream>
    #include <string>

    void main()
    {
      
    string word;
      
    word="Hello World~";
      
    cout << word << endl;
      
    cin >> "what";

    Never end on learning~
