Why when you change the order of curly braces affects the result of if and else statement? Check the code below and explain why

Question

int age = 17;
if (age > 14) {
if(age > 18) {
Console.WriteLine("Adult");}} // i placed curly braces here and the answer differ with the code below! Why please help here am stuck!

else {
Console.WriteLine("Teenager");}
// NO OUTPUT

int age = 17;
if (age > 14) {
if(age > 18) {
Console.WriteLine("Adult");}

else {
Console.WriteLine("Teenager");}} // i placed curly braces here and results differ with the above!

//OUTPUT TEENAGER

Answer 1

After age>14 is satisfied, age>18 is not satisfied.

Answer 2

Ok. I see. It is currect. First example You close 2 } curlybrances, so... You exit out of 2 IFs. Thus the ELSE is executing somethin <= 14 that is why "no outputs"

Of course the second example is more currect than first about our human logic.
