Why is there no output for the second or third ifs?

Question

when I change age to other numbers that should change the output, it just says no output

static void Main(string[] args)
{
int age =16;
if(age > 16){
if(age < 18){

Console.WriteLine("adult.");

}
else {
if(age<16){
if(age>12){
Console.WriteLine("teen");
}
}
}
}
else {
if(age<12){

Console.WriteLine("kid");

}
}
}
}
}

Answer 1

no. those are for the beginning of the code

Answer 2

1) Its good practice set the language name like tag of your question

2) Its MORE good practice save your code on SL code playground and post in Q&A a link to it and not copy/paste your code

3) Seem to me that with age=16 no code its runned

4) You know that can use logical AND and OR if your condition for check multiple conditions? Example:

if(age>16 && age<18){
/* this code will run only if age its 17 */
.......
}
