How can I use c++ 'break' code in nested for loop?

Question

How will be the effect of 'break' statement in nested for loops?

Answer 1

break statement is used to come out from the innermost loop.
say you are using three loop variables like this
for(i=1;i<=10;i++)
{
if(i%2 ==0) break;
cout< for( j=1;j<=10;j++)
{
if(j%2==0) break;
cout< for(k=1;k<=10;k++)
{
if(k%2==0) break;
cout< }

}
}
Now output of this loop is as follow
when i is odd it will enter the j loop otherwise it will exit from the i loop and execute the instruction just after the i loop.
and if it entered in j loop then it will come out from the j loop when it become odd. and same in the case of k.
so output is
1
1
1
because k is break at k=2 then j becomes 2 and it break it and then i become 2 and exit from all loop

Answer 2

if u have break in nested loops,be sure of where u r placing the break.
ex:-
if(x==10 || 20)
{
if(x==10)
{printf("%d",x);
break;
}
break;
if(x==20)
printf("HI");
}
this will break the loop itslef after the 1st print statement.
