Multiple if statements

OO7 (2)
Im trying to create a simple age calculator that has cout of custom messages, Im trying to use multiple "if" statements. It often shows nothing in the console when i run it. why is that so? I believe i covered most of the ages, do i need an else statement?

Where is ages of 15 and 19 for these? You are just applying lower than/higher than... Hint given

Your program is good.but try using a series of IF...ELSE statement instead of IF only.
e.g
if(age>1&&<15)
{cout<<"......."};
else is(...)
{"....."};
//continue using else if until the last expression then you can use single else

If you use else as Aminu Bishir suggested you can simplify the conditions. As long as the ages always increase you only need to test the upper bound.

        cout<<"You're a child!";
    } else if(age<19) { // no need to check lower bound as already handled
        cout<<"You're a teenager!";
    } else if(age<30){

    // And what about "people" 400 and older??

Thank you all for your insight, i made the program work thanks to your help, and @andy westken i added 400 incase someone wanted to be silly.

i added 400 incase someone wanted to be silly.

I guessed that. But what if they said they were 2000 years old?
