Conditionals & Logic
Else If

So what happens if you want more than two possible outcomes?

This is where else if comes in!

if (condition) {

  some code

} else if (condition) {

  some code

} else {

  some code

}

The else if statement always comes after the if statement and before the else statement. The else if statement also takes a condition.

And you can have more than one of them! Here’s an example with three of them:

if (grade == 9) {

  std::cout << "Freshman\n";

} 
else if (grade == 10) {

  std::cout << "Sophomore\n";

}
else if (grade == 11) {

  std::cout << "Junior\n";

} 
else if (grade == 12) {

  std::cout << "Senior\n";

}
else {

  std::cout << "Super Senior\n";

}

Instructions

1.

In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution.

Write an if, else if, else statement that:

  • If ph is greater than 7, output “Basic”.
  • If ph is less than 7, output “Acidic”.
  • If neither, output “Neutral”.

Remember to take a look at the hint if you are stuck.
