only able to enter input after first prompt, then program finishes c++ -


so i'm trying put program project, , it's behaving strangely me. here's example of happens in console:

compute completion time current time , waiting period

current time:

enter 24 hour time in format hh:mm 12:50
waiting time:
enter 24 hour time in format hh:mm completion time in 24 hour format:
4644952:4198980
enter y or y continue, other halts
process returned 0 (0x0) execution time : 3.927 s
press key continue.

the part in bold part input , runs through cout statements without letting me input second pieces of data. outputs garbage number calculation function. here code:

#include <iostream> using namespace std; void getendtime(int c_hours, int c_minutes, int w_hours, int w_minutes, int& e_hours, int& e_minutes); void getcurrenttime(int& c_hours, int& c_minutes); void getwaitingtime(int& w_hours, int& w_minutes); void runloop(); int main() {     char select;     cout << "compute completion time current time , waiting period \n";     {         runloop();         cout << "enter y or y continue, other halts";         cin >> select;     } while (select == 'y' || select == 'y');     return 0; } void runloop() {     int current_hours, current_minutes, waiting_hours, waiting_minutes;     int end_hours, end_minutes;     getcurrenttime(current_hours, current_minutes);     getwaitingtime(waiting_hours, waiting_minutes);     getendtime(current_hours, current_minutes, waiting_hours, waiting_minutes, end_hours, end_minutes);     cout << "completion time in 24 hour format:\n" << end_hours << ":" << end_minutes << endl;     } void getcurrenttime(int& c_hours, int& c_minutes) {     cout << "current time:\n"     << "enter 24 hour time in format hh:mm ";     cin >> c_hours >> c_minutes;  } void getwaitingtime(int& w_hours, int& w_minutes) {     cout << "waiting time:\n"     << "enter 24 hour time in format hh:mm ";     cin >> w_hours >> w_minutes; } void getendtime(int c_hours, int c_minutes, int w_hours, int w_minutes, int& e_hours, int& e_minutes) {     if ((c_hours + w_hours) >= 24) {         e_hours = (c_hours + w_hours - 24);     }     else {         e_hours = (c_hours + w_hours);     }     if ((c_minutes + w_minutes) >= 60) {         e_hours += 1;         e_minutes = (c_minutes + w_minutes) - 60;     }     else {         e_minutes = c_minutes + w_minutes;     }     return; }

i pretty new apologize if there obvious missing. i'm hoping 1 of can me out here, i'm totally stumped why not working! thanks!

the problem having cin entering error state , every subsequent call cin automatically fail , program continue on. when time in:

void getcurrenttime(int& c_hours, int& c_minutes) {     cout << "current time:\n"     << "enter 24 hour time in format hh:mm ";     cin >> c_hours >> c_minutes;  }

you not eating : exist in 12:50. such tries insert : minutes , fails.

what need call cin.get() eat : , minutes.

void getcurrenttime(int& c_hours, int& c_minutes) {     cout << "current time:\n"     << "enter 24 hour time in format hh:mm ";     cin >> c_hours;     cin.get(); // eats :     cin >> c_minutes;  }
