Foreach循环在C ++中相当于C＃ [英] Foreach loop in C++ equivalent of C#

问题描述

如何将此代码转换为C ++？

How would I convert this code to C++?

string[] strarr = {"ram","mohan","sita"};    
foreach(string str in strarr) {
  listbox.items.add(str);
}

推荐答案

Using standard library alone:

std::string strarr[] = {"ram", "mohan", "sita"};
for(int i = 0; i < 3; ++i) {
  listbox.items.add(strarr[i]);
}

或

std::string strarr[] = {"ram", "mohan", "sita"};
std::vector<std::string> strvec(strarr, strarr + 3);
std::vector<std::string>::iterator itr = strvec.begin();
while(itr != strvec.end()) {
  listbox.items.add(*itr);
  ++itr;
}

使用批注：

boost::array<std::string, 3> strarr = {"ram", "mohan", "sita"};
BOOST_FOREACH(std::string & str, strarr) {
  listbox.items.add(str);
}

---

C++11 ：

std::array<std::string, 3> strarr = {"ram", "mohan", "sita"};
for(std::string & str : strarr) {
  listbox.items.add(str);
}
