The discussion centers on the use of cin.ignore() in C++ to manage input when switching from numeric input to string input. Users reported that after using cin.ignore(), the program incorrectly reads input, specifically capturing only part of the string. The solution presented involves removing cin.ignore() before the getline() function, which resolved the issue of capturing the entire input string correctly. This adjustment ensures that the input buffer is properly managed between different types of input.

if(count%2==0){ //for user 1
cout<<"User 1"<<endl;
cout << "Please enter your move: ";
cin.ignore();
getline(cin,str);
//do something
}
else if (count%2!=0){ //for user 2
cout<<"User 2"<<endl;
cout << "Please enter your move: ";
cin.ignore();
getline(cin,str);
//do something
}Before this part, I was getting numbers elsewhere using cin. And I add cin.ignore after that and I deleted cin.ignore before getline and it fixed. I'm just seeing your answer, but thank you anyway.Joshy said:
