Answer 1

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

char string[128];

do {

cin.getline(string, sizeof(string), '0');

cout << endl;

for (int i = 0; i < sizeof(string); i++){

if (string[i] == '-1') {

getch();

return 0;

}

}

} while (true);

cout << endl;

getch();

return 0;

}
