MODIFYING CODE USING C++

Here is what I have to do: Read some text into a vector, storing each word in the input as an element in the vector. Transform each word into uppercase letters. Print the transformed elements from the vector, printing eight words to a line.

Here is what I have so far. But I cannot get the program to stop. I am trying to get the program to terminate after a user inputs DONE.

#include #include #include #include #include using std::cin; using std::cout; using std::endl; using std::istringstream; using std::string; using std::vector;

using namespace std;

int main() { string s; vectorv; cout << "Please enter amount needed for string: "; int amount; cin >> amount; for(int i = 0; i < amount; i++) while (true) { cin >> s; if (s == "DONE") break; v.push_back(s); } for(int i = 0; i < v.size(); ++i) { for(int j = 0; j < v[i].size(); ++j) { if(islower(v[i][j])) { v[i][j] = toupper(v[i][j]); } } } for(int i = 0; i < v.size(); ++i) { cout << v[i] << " "; } return 0; }
