What is the break keyword in C++?

Overview

The break keyword in C++ is used to break out of a switch block. This stops the execution of subsequent code inside the block. When a match is found in the switch block, the job is done. Therefore, there’s no need for more testing.

Note: The switch statements are a block of code that act like an if-else-if statement.

The break keyword saves a lot of time for execution. This is because it ignores the execution of the subsequent code in the switch block when a match is found.

#include <iostream>
using namespace std;
int main() {
  int month = 5;
  switch (month) {
  case 1:
    cout << "January";
    break;
  case 2:
    cout << "Februray";
    break;
  case 3:
    cout << "March";
    break;
  case 4:
    cout << "April";
    break;
  case 5:
    cout << "May";
    break;
  case 6:
    cout << "June";
   break;
  case 7:
    cout << "July";
    break;
  case 8:
    cout << "August";
    break;
  case 9:
    cout << "Septembe";
   break;
  case 10:
    cout << "October";
    break;
  case 11:
    cout << "November";
   break;
   case 12:
    cout << "December";
    break;
  }
  return 0;
}
