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.

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.

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 succesfully:

sh-
4.3$ lci main.lo
16

Program to Make an Array

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

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

Program to Calculate the Factorial of a Number

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

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

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? + - * /
