My solution:

#include

// Define needs_water() here:
std::string needs_water(int days, bool is_succulent)
{
std::string watering;

if (days > 3 && is_succulent == false)
{
watering = “Time to water the plant.”;
}
else if (days <= 12 && is_succulent == true)
{
watering = “Don’t water the plant!”;
}
else if (days >= 13 && is_succulent == true)
{
watering = “Go ahead and give the plant a little water.”;
}
else
{
watering = “Don’t water the plant!”;
}

return watering;
}

int main()
{
std::cout << needs_water(1, true) << “\n”;
}

Maybe someone knows a better solution?

It does’t matter if I put the int value first and then the bool and viceversa right? I think codecademy needs my code to match theirs in order for me to continue. I was doing the bool first then the int and It was giving me an error. Of course I made the that the passed parameters were in the same order as in the fuction itself.

This still worked :slight_smile:

std::string needs_water(int days, bool is_succulent) {
  if (is_succulent == false && days > 3) {
    return "Time to water the plant.";
  } else if (is_succulent == true && days <= 12) {
    return "Dont water the plant!";
  } else if (is_succulent == true && days >= 13) {
    return "Go ahead and give the plant a little water.";
  } else {
    return "Dont water the plant!";
  }
}

int main() {
  
  std::cout << needs_water(10, false) << "\n";
  
}
std::string needs_water(int days, bool is_succulent) {
  
  if (is_succulent == false && days > 3) {
    return "Time to water the plant.";
  } else if (days <= 12) {
    return "Don't water the plant!";
  } else if (days >= 13) {
    return "Go ahead and give the plant a little water.";
  } else { 
    return "Don't water the plant!";
  }
 
}

Because of the nature of the cases, you don’t need to include the boolean values for the last 3 cases. There is only one condition with the false bool, so as long as it’s first everything is okay.

Hey guys, just wanted to offer a tip:
“is_succulent == true” is the same a “is_succulent” and “is_succulent == false” is the same as “!is_succulent”

That is what I did:

std::string needs_water(int days, bool is_succulent){

if (is_succulent == false && days > 3){

return "Time to water the plant.";}

if (is_succulent == true && days >= 13){

return "Go ahead and give the plant a little water.";}

return “Don’t water the plant!”;

}
