So I have a function that keeps skipping over the first getline and straight to the second one. I tried to clear the buffer but still no luck, what's going on?
void getData(char* strA, char* strB)
{
cout << "Enter String 1: "; // Shows this line
cin.clear();
cin.getline(strA, 50); // 50 is the character limit, Skipping Input
cout << endl << "Enter String 2: "; // Showing This Line
cin.clear();
cin.getline(strB, 50); // Jumps Straight to this line
}
Make sure you didn't use cin >> str
. before calling the function. If you use cin >> str
and then want to use getline(cin, str)
, you must call cin.ignore()
before.
string str;
cin >> str;
cin.ignore(); // ignores \n that cin >> str has lefted (if user pressed enter key)
getline(cin, str);
In case of using c-strings:
char buff[50];
cin.get(buff, 50, ' ');
cin.ignore();
cin.getline(buff, 50);
ADD: Your wrong is not probably in the function itself, but rather before calling the function. The stream cin
have to read only a new line character \n'
in first cin.getline
.
