The question requires writing a while loop statement. Each loop reads two ints and pushes them into the vector. When '|' is entered, the program ends.
The problem now is that the question requires the input of two different types. character

#include  using namespace std; int main() { int num_1, num_2; char stop; while (cin >> stop) { if (stop == '|') { break; } else { cin >> num_1 >> num_2; cout << num_1 << " " << num_2 << endl; } } return 0; }

The above program is a solution I can think of. At this time, you can use | to end the loop, but there is a problem here. The input stream object will discard the first number read (because 1 is not a char type)

input: 123 56 output: 23 56

Do you have any other solutions? Thank you~~~
