i want to creat a program that can print my name in "*" (stars) but i have no idea on how to start it.. or what do to.. im still a newbie.. all i have created ever as a cal..(for thouse who know) and how i want to creat a program that can print out my name in * . also if i do i want to understand itz functions.. would anyone mind telling me how to start this.. or how to learn how to do this.. thanx (great knowledge for a stupid kid.)
ok this code will probly be pretty hard to understand but I will try, first you need to understand boolean algebra:
#include <stdio.h>
long charset[24];
/*
*** **** *** **** ***** ***** *** * * *** * * * *
* * * * * * * * * * * * * * * * * * *
***** **** * * * *** *** * ***** * * ** *
* * * * * * * * * * * ** * * * * * * * *
* * **** *** **** ***** * *** * * *** *** * * *****
* *
** **
* * *
* *
* *

ok each letter is defined as a number, using long variables you have 32 distinct bits in it, to test for each one you can get the number and do
num & value
where num is the number definition and value is say 4 to test the 3rd bit from the right.
to create a new letter, type in the letter as you want it to look like, like I have done at the top and type a * as 1 and a space as 0, and start from the bottom right and go backwards so
A = 1000110001111111000101110
A to M are already done.
Ok now to explain the code, the function printchars checks how many letters it gets passed, it then analyses 1 letter at a time
it minus's 65 off the letter so that A will equal 0, B equals 1, etc
it then looks at the definition for the specific letter defined in charset and tests each bit in the integer starting from bit 1 and stops at bit 25 which is defined by 2nd for statement (33554431 is the maximum value that a character could have using a 5x5 structure. if a value is read then it will print a * in the correct position.
Hope this helps if ya need any more help or explanation just let me know and I will comment the code.
Enjoy

errr well first off all thanx for yoru reply second im to stupid and the code is to advanced for me hehe.... is there another way on how to creat it more lipler.....thanx
you could probably hardcode it like this
Code:cout<<"****"; cout<<"* *"; cout<<"* *"; cout<<"****"; cout<<"* *"; cout<<"* *"; cout<<"* *";
-
i think "ihsir" is missing "endl;"
