C++ cin questions
- by Kim
This seems to be weird:
int main(int argc, char* argv[]) {
cout << "function main() .." << '\n';
char ch = 0;
double number_value=1.1;
cin >> ch;
cin.putback(ch);
cin >> number_value;
cout << "1 .. " << " " << cin.good() << " " << number_value << '\n';
cin >> number_value;
cout << "2 .. " << " " << cin.good() << " " << number_value << '\n';
return 0;
}
If I input the following:
7a 1
I get the following:
function main() ..
7a 1
1 .. 1 7
2 .. 0 0
I understand the:
1 .. 1 7
but why the variable number_value is 0.
cin.good() shows failure so nothing would have read and the value in number_value from the previous assignment would remain. I expect the value of 7.
