Y have error for test 3, 4 and i don't know for why?

Question

Admission to the pool is free for children under 7 years of age.
The given program takes age as an input.

Task
Complete the code to output "free" if the child's age is less than 7.

Sample Input
6

Sample Output
free

Answer 1

You are comparing the input age to itself age. This will produce "free" for any input.
if (age<=6){cout<<"free"<<endl;}
else if (age>6){cout<< ""<<endl;}

Now comparing to 6.

Answer 2

My code : #include <iostream>
using namespace std;

int main() {
int age;
cin >> age;

// your code goes here
if (age<=age){cout<<"free"<<endl;
}
else if (age>age){cout<< ""<<endl;}
return 0;
}

Answer 3

Thank's

Answer 4

#include <iostream>

int main() {
int age;
std::cin >> age;

// your code goes here
if (age <= 7){
std::cout << "free";
}
else if (age > 7){
std::cout << "";
}

return 0;
}
// FZ

Answer 5

#include <iostream>
using namespace std;

int main() {
int age;
cin >> age;

// your code goes here
if (age<=7){cout<<"free"<<endl;
}
else if (age>7){cout<< ""<<endl;}
return 0;
}

Good Luck

Answer 6

#include <iostream>

return 0;
}

Answer 7

int age;
cin >> age;

// your code goes here
if (age <= 7){
cout<<"free";
}else if (age > 7){
cout<<"";
}

this one works
