Using break we can leave a loop even if the condition for its end is not fulfilled. It can be used to end an infinite loop, or to force it to end before its natural end. For example, we are going to stop the count down before its natural end (maybe because of an engine check failure?):// break loop example#include <iostream>using namespace std;int main (){ int n; for (n=10; n>0; n--) { cout << n << ", "; if (n==3) { cout << "countdown aborted!"; break; } } return 0;} 10, 9, 8, 7, 6, 5, 4, 3, countdown aborted!
