So far, we haven’t really had to deal with logic, have we?

Logic is about evaluating the truth and falsehood of a statement.

In programming, it is important to do some things based on whether or not certain conditions hold (that is, evaluate to true).

A good example is describing the price of a book. If the price is greater than 200 rupees, you might want to say “expensive” and otherwise you might want to say “not expensive”. In Vaklipi, let’s say the book’s price is referred to by the variable p, you can say the following:

If p is greater than 200, say “expensive” else say “not expensive”.

program | run() | |

p is 150. If p is greater than 200, say “expensive” else say “not expensive”. | not expensive |

We can also say things like:

Say “boo” if 10 plus 2 is greater than 3.

Here below is a set of examples in English:

com.aiaioo.VaklipiOutputFixture | ||

program | run() | |

Say “boo” if 10 plus 2 is greater than 3. | boo | |

x = 2. y is 3. If x is less than y, print y else print x. | 3.0 | |

x = 2. y is 3. If x is more than y, max is x else max is y. Say max. | 3.0 |

Now, if you were talking Hindi, you would say something like:

अगर ३ का मान २ से ज्यादा है तो ३ बोलो. (If 3 is greater than 2, say 3)

program | run() | |

अगर ३ का मान २ से ज्यादा है तो ३ बोलो. | 3.0 |
