best practice to leave a nested loop

Valerie Meunier

in order to leave a nested for- loop, what's the best metnod? (goto or break?)

Thanks.

for (int i = 1; i <= 8; i++)
for (int j = 9; j >0; j--)
for (int k = 1; k <= 7; k+=2)

{
prod = i * j * k;
if (prod > 100)
break;

}
}
}

}

Accepted answer
break is best. goto is good if you are not using in lot of places.

I think goto will be better.
for(int 1=0; i<1000; i++)
{
for(int j=0; j<1000; j++)
{
if (condition) {
goto end;
}
}
}

goto statement just jump out of a nested loop to a labelled statement so there is minimal code approach.

break statement leaves only the current loop so for nested loop, break should execute in every loop. Takes extra code.

goto statement leaves the nested loop easily than break statement.

Sample code for break statement:
for ( int i=1; i<=9; i++){
bool b= false;
for(int j=1;j<=9;j++){
int prod=i*j;
if(prod>=20)
{
b=true;
break;
}
Console.WriteLine("{0}", prod);
}
if(b){
break;
}
}
Console.WriteLine("End");
Sample code for goto statement:
for(int i=1;i<=9;i++){
for(int j=1;j<=9;j++){
int prod = i*j;
if(prod >=20)
{
goto LabelEnd;
}
Console.Write("{0}", prod);
}
}
LabelEnd:
Console.WriteLine("End");
