if i text 21 it stacks. program says you are a child. you are a teenager. you are adult. how can i delete this "stack". #include <iostream> using namespace std; int main() { int age; cin>>age; if (age>=14){ cout<<"You're a Teenager"<<endl; } if (age>=18){ cout<<"You're adult"<<endl; } if (age>=0){ cout<<"You're a Child"<<endl; } else{ cout<<"Are u stupid ?"<<endl; } return 0; }

Answer 1

Hi Peter,

If you input age as 21, let's go through it step by step.

Is 21 greater than or equal to 14? Yes.
cout <<

Is 21 greater than or equal to 18? Yes.
cout <<

Is 21 greater than or equal to 0? Yes.
cout <<

This is your problem.

The best way I could recommend a fix for this is to nestle the if-else statements, like this:

if (age >= 18)
{
cout <<
}
else
{
if (age >= 14)
{
cout <<
}
else
{
if (age >= 0)
{
cout <<
}
else
{
cout <<
}
}
}

Thanks for your question!

Answer 2

Thank you! it worked as you said. But i found another answer: I could always after an if- Loop write break; ;)

Answer 3

You don't need to nest them like that. You can just do:

if (condition) { }
else if (condition) { }
else { }

Answer 4

If you solve problem via break; you should write expressions in the correct order.
