break

The break statement forces the loop from which it is called to be exited. If such a loop is contained within another loop, the containing loop will keep iterating. Given the nested loops:

for(int i = 0; i < 5; i++)
{
   for(int j = 0; j < 5; j++)
   {
       cout << i << " " << j << " - ";
       if(i == j)
            break; // breaks only innermost for
   }
   cout << endl;
}

Whenever the condition:

i == j

is met, the break statement is called. As a consequence the inner loop is broken out of, and

cout << endl;

is executed. After that, if the conditional statement:

i < 5

is met, a new iteration of the outer loop takes place, possibly re-entering the inner loop - if the:

j < 5

condition is met.

Example


#include <iostream>
using namespace std;

int main()
{   
    for(int i = 0; i < 5; i++)
    {
        for(int j = 0; j < 5; j++)
        {
             cout << i << " " << j << " - ";
             if(i == j)
                 break; // breaks only innermost for
        }
        cout << endl;
    }
    cout << endl;
}

Output

0 0 -
1 0 - 1 1 -
2 0 - 2 1 - 2 2 -
3 0 - 3 1 - 3 2 - 3 3 -
4 0 - 4 1 - 4 2 - 4 3 - 4 4 -
