// When you need to check some value
//  a conditional statement might help you

int valueToCheck = 2 + 2;
if (valueToCheck == 4)
{
  printline("Yay! 2 + 2 = 4");
}

// Conditional statement uses condition in parenthesis
//  after `if` keyword and executes command(s) after
//  if condition turns out to be true

// Otherwise, to execute block when condition turns
//  out to be false, you can use `else` keyword:

int age = 30;

if (age <= 20)
  printline("You're too young");
else
{
  age = 20;
  printline("You look too young!");
}

// NOTE: If you need to execute only one statement
//  inside `if` or `else` block, then the curly
//  braces can be omitted.
