How would I convert this code to C++?
string[] strarr = {"ram","mohan","sita"}; foreach(string str in strarr) { listbox.items.add(str); }
The every() function is a good alternative to forEach, let us see an example with a test implementation, and then let's return out of the every() function when a certain condition meet.
How foreach loop works? The in keyword used along with foreach loop is used to iterate over the iterable-item . The in keyword selects an item from the iterable-item on each iteration and store it in the variable element . On first iteration, the first item of iterable-item is stored in element.
The continue statement in C language is used to bring the program control to the beginning of the loop. The continue statement skips some lines of code inside the loop and continues with the next iteration.
Working of the foreach loop in C++ So basically a for-each loop iterates over the elements of arrays, vectors, or any other data sets. It assigns the value of the current element to the variable iterator declared inside the loop.
std::array<std::string, 3> strarr = {"ram", "mohan", "sita"}; for(const std::string& str : strarr) { listbox.items.add(str); }
std::string strarr[] = {"ram", "mohan", "sita"}; for(int i = 0; i < 3; ++i) { listbox.items.add(strarr[i]); }
or
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; }
boost::array<std::string, 3> strarr = {"ram", "mohan", "sita"}; BOOST_FOREACH(std::string & str, strarr) { listbox.items.add(str); }
