我想要使​​用boost数组

但是我收到了这个错误:

错误:'array':模糊符号

这是我的代码:

#include <iostream>
#include <boost/array.hpp>
#include <boost/regex.hpp>

using namespace boost;

using namespace std;



int main(int argc, char* argv[])
{
    array<int, 10> a{3};

    cout << "a[0]= " << a[0];

    return 0;
}

当我包含boost库时会出现此错误

任何的想法 ？

我正在尝试使用工作代码来替换行的文本.使用boost_1_64_0.

getline (ifs, line);
cout << line << endl;

// 1.
boost::replace_all(line, "abc", "hij");
boost::replace_all(line, "def", "klm");

// 2.
line = boost::replace_all_copy
boost::replace_all_copy<string>
(
 ("abc def abc def", "abc", "hij")
 ,  "def"
 ,  "klm"
);

我收到这些错误:

main.cpp||In function 'int main()':|

我有一个普通的指针char *,如何转换char *为boost::shared_ptr？

char *str = "abcdfg";
boost::shared_ptr<char> ss = ?(str);

我试图用rhapsody定义一个指向我结构的智能指针,我已经包含了头文件"memory".但我有上面的错误

 typedef std::shared_ptr<my_structure> %s;
