boost::array of std::string items in Qt Creator

boost::array is a template class which enables it to be able to be declared for different type of items. There exists an array as a member inside boost:array template class declaration so boost:array also acts a C-array wrapper with fixed number of items inside it.

Following sample project created by qt creator and contains following files:

1- BoostArrayOfStrings.pro
2- main.cpp

BoostArrayOfStrings.pro file contains project configuration.

TEMPLATE = app
CONFIG += console

SOURCES += main.cpp

INCLUDEPATH += /home/tufan/boost_1_55_0

Boost header files and libraries are located under the directory : /home/tufan/boost_1_55_0

main.cpp file contains main method.

#include <boost/array.hpp>
#include <string.h>

using namespace std;

int main()
{
    typedef boost::array<string,3> boostArray;
    boostArray stringArray;

    stringArray[0] = "FirstStringMember";
    stringArray.at(1) = "SecondStringMember";
    stringArray.at(2) = "ThirdStringMember";

    // some common container operations
    cout << "size:     " << stringArray.size() << endl;
    cout << "empty:    " << boolalpha << stringArray.empty() << endl;
    cout << "front:    " << stringArray.front() << endl;
    cout << "back:     " << stringArray.back() << endl;
    cout << "elements:    " << endl;

    for(boostArray::iterator iter(stringArray.begin()); iter != stringArray.end(); ++iter)
    {
        cout << *iter << endl;
    }

    return 0;
}

boost array contains 3 string items. Members of the array are initialized by using array subscript operator and at() function.

size:     3
empty:    false
front:    FirstStringMember
back:     ThirdStringMember
elements:  
FirstStringMember
SecondStringMember
ThirdStringMember
