Breaking out of nested loops in C++ [duplicate]

Answer 1

For example

for ( int i = 0; i < m; i++ ) 
{
    bool exit = false;

    for ( int j = 0; !exit && j < n; j++ ) 
    {
         if ( ( exit = some condition ) ) 
         {
             // Do something and break...
         }
    }

    if ( exit ) break;
}

Or

bool exit = false;

for ( int i = 0; !exit && i < m; i++ ) 
{
    for ( int j = 0; !exit && j < n; j++ ) 
    {
         if ( ( exit = some condition ) ) 
         {
             // Do something and break...
         }
    }
}
