i learning std::string , want : input string every second letter make uppercase output new string #include "stdafx.h" #include <iostream> #include <string> using namespace std; int main() { string mystr; getline(cin,mystr); if (mystr.begin() != mystr.end()) { (auto = mystr.begin(); != mystr.end() ; += 2) *it = toupper(*it); } cout << mystr; system("pause"); return 0; } but after input getting error here : it += 2 leads out of bounds, if loop ending condition it != mystr.end() . dereferencing *it = toupper(*it); is undefined behavior. it += 2 never give exact iterator value of mystr.end() have loops termination condition. as comment: so how can fix ? just keep simple , understandable, e.g. using like for (size_t = 0; < mystr.length() ; ++i) { if(i % 2) { // every second letter ... mystr[i] = toupper(mystr[i]); } }

i trying implement iterstitial ads admob. managed displayed in test mode. however, showed blank page "afma_receivemessage not defined" error when running live. i have read many post relating "afma_receivemessage not defined" issue. seemed problem ads has running on separate thread gain network access. however, if move loadad , show methods new thread (like in afma_receivemessage not defined or interstitial admob doesn't work : afma_receivemessage not defined ), complain has run on main thread!! if use runonuithread method, go "afma_receivemessage not defined" problem. i confused conflicting solutions each other. (it has run on uithread while has on separate thread gain network access?) has have working example interstitial ads admob (not in test mode)?
