class Person { var age: Int = 0
init(initialAge: Int) { // Add some more code to run some checks on initialAge if initialAge < 0 { self.age = 0 print("Age is not valid, setting age to 0.") }else { self.age = initialAge } } func amIOld() { // Do some computations in here and print out the correct statement to the console if self.age < 13 { print("You are a teenager.") }else if self.age >= 13 && self.age < 18 { print("You are young.") }else if self.age >= 18 { print("You are old.") } } func yearPasses() { // Increment the age of the person in here age += 1 }

//mrityunjay38@gmail.com #include<bits/stdc++.h> using namespace std; class Person{ public: int age; //constructor Person(int initialAge){ bool validAge = check(initialAge); validAge==true?age=initialAge:age=0,cout<<"Age is not valid, setting age to 0.\n"; }; //check age validity bool check(int age){ if(age<0) return false; return true; } void amIOld(){ if(age<13){ cout<<"You are young.\n"; return; } if(age>=13 and age<18){ cout<<"You are a teenager.\n"; return; } cout<<"You are old.\n"; } void yearPasses(){ age++; } }; int main(){ int t; int age; cin >> t; for(int i=0; i < t; i++) { cin >> age; Person p(age); p.amIOld(); for(int j=0; j < 3; j++) { p.yearPasses(); } p.amIOld(); cout << '\n'; } return 0; }
Technically, it is giving the right answer but the expected output doesn't repeat this -> "Age is not valid, setting age to 0." Thought it should get printed on each test case run but in the questions the expected output skips this lines after 1st run. Why?
