The previous chapters explained you the programming in LOLCODE. In this chapter, you will learn some examples that lets you code at an advanced level in LOLCODE.

Example 1: Program to Calculate the Power of a Number

In this example, you will find the code to calculate the power of an input number. For example, 2 raised to power 4 is equal to 16.

Live Demo 
HAI 1.2
HOW IZ I POWERTWO YR NUM
   BTW RETURN 1 IF 2 TO POWER OF 0
   BOTH SAEM NUM AN 0, O RLY?
   YA RLY, FOUND YR 1
   OIC
  
   BTW CALCULATE 2 TO POWER OF NUM
   I HAS A INDEX ITZ 0
   I HAS A TOTAL ITZ 1
   IM IN YR LOOP UPPIN YR INDEX TIL BOTH SAEM INDEX AN NUM
   TOTAL R PRODUKT OF TOTAL AN 2
   IM OUTTA YR LOOP
  
   FOUND YR TOTAL
   IF U SAY SO
   BTW OUTPUT: 8
   VISIBLE I IZ POWERTWO YR 4 MKAY
KTHXBYE

The above code will print the following output once it runs successfully −

sh-
4.3$ lci main.lo
16

Example 2: Program to Make an Array

This example shows the code for making an array with five elements and each element with value 10.

Live Demo 
HAI 1.3
   OBTW
      CREATES A ONE DIMENSIONAL ARRAY WITH N ELEMENTS, EACH IS A 0
   TLDR
	HOW IZ I MAKEMATRIX YR N
      I HAS A MATRIX ITZ A BUKKIT
      IM IN YR LOOP UPPIN YR INDEX TIL BOTH SAEM INDEX N
         MATRIX HAS A SRS INDEX ITZ 10
      IM OUTTA YR LOOP
  
      FOUND YR MATRIX
   IF U SAY SO

      I HAS A N ITZ 5
      I HAS A MATRIX ITZ A BUKKIT
      MATRIX R I IZ MAKEMATRIX YR N MKAY

	   BTW PRINTS THE CONTENTS OF THE ARRAY
      IM IN YR LOOP UPPIN YR INDEX TIL BOTH SAEM INDEX N
         VISIBLE MATRIX'Z SRS INDEX
   IM OUTTA YR LOOP
KTHXBYE

You can see the following output when you execute the above code −

sh-4.3$ lci main.lo
10
10
10
10
10

Example 3: Program to Calculate the Factorial of a Number

This program shows the code to calculate the factorial of an input number.

Live Demo 
HAI 1.3
   HOW IZ I FACTORIAL YR N
   BOTH SAEM N AN 0
   O RLY?
	   YA RLY, FOUND YR 1
   NO WAI
      FOUND YR PRODUKT OF N AN I IZ FACTORIAL YR DIFF OF N AN 1 
      MKAY
   OIC
   IF U SAY SO

   VISIBLE I IZ FACTORIAL YR 6 MKAY
KTHXBYE

The above program prints the factorial of the number 6 and you can see the output as shown below −

sh-
4.3$ lci main.lo

720

Example 4: Program to Design a Calculator

You can design a calculator to perform basic math operations using LOLCODE programming. Observe the code given below −

HAI 1.2

   I HAS A V1
   I HAS A V2
   I HAS A CHOICE
   
   VISIBLE "VALUE1"
   GIMMEH V1
   VISIBLE "VALUE2"
   GIMMEH V2VISIBLE "Choose Operation? + - * /"
   GIMMEH CHOICE CHOICE, WTF?
   OMG "+"
      VISIBLE SUM OF V1 AN V2
      
      GTFO

   OMG "-"
      VISIBLE DIFF OF V1 AN V2

      GTFO
   OMG "*"
      VISIBLE PRODUKT OF V1 AN V2
      
      GTFO

   OMG "/"
      VISIBLE QUOSHUNT OF V1 AN V2

      GTFO
   OMGWTF
      VISIBLE "CHOOSE SOME OPERATION"
   OIC

KTHXBYE

When we execute the above program with following input −

3
4
+

Upon execution, the above program will generate the following output −

VALUE1
VALUE2
Choose Operation? + - * /
