using namespace std;

double hey(int x){

if(x==2)

return 1;

int i=0;

if (x%2==0){

while(i<=2){

cout<<(x/2)<<endl;

i++;

break;

}

}

if (x%2==1){

while(i<=2){

i=3*x+1;

cout<<i<<endl;

}

return 1;

}

}

int main()

{

int n;

cout<<"insert a number to check how many steps to reduce down to 2"<<endl;

cin>>n;

cout<<hey(n)<<endl;

return 0;

}

I couldn't

Answer 1

The code will be

#include<iostream>

using namespace std;

double hey(int x) {

int count=0;
while(x!=2){
if(x%2==0)x=x/2;
else x=3*x+1;
count++;
}
return count;
}

int main()
{

int n;
cout << "insert a number to check how many steps to reduce down to 2" << endl;
cin >> n;
cout << hey(n) << endl;
return 0;

}

The output is
