 Posted: Wed Oct 29, 2008 4:47 pm Post subject: Simple Java program? (Loops)? |
 |
|
I need to create this using loops:
(The underlines are spaces)
____*
___***
__*****
_*******
*********
*********
_*******
__*****
___***
____*
Can anyone do it and post the source code? 
Here is a chart in case you don’t feel like counting:
Row Spaces Stars
1 4 1
2 3 3
3 2 5
4 1 7
5 0 9
6 0 9
7 1 7
8 2 5
9 3 3
10 4 1

Not your personal homework-monkeys. Try learning something.

why not do it in batch o.o
:start
echo ____*

Your program prints it repeatedly, thats not what he wants. He wants to print it once using loops, duh.
for(int i; i < 1; i++) {
System.out.println("____*");
System.out.println("echo ___***");
System.out.println("echo __*****");
System.out.println("echo _*******");
System.out.println("echo *********");
System.out.println("echo *********");
System.out.println("echo _*******");
System.out.println("echo __*****");
System.out.println("echo ___***");
System.out.println("echo ____* ");
}

Single look at your chart for patterns the answers of stars are always odd.. and the counter could start at X.. so just start it at 4 now you understand the pattern
you will be going to use 2 for loops to make it look good.. with one counting down and other counting up
or you could use one while loop with a boolean and add a if statements if(counter == 0) then
boolean = true;
if(boolean) then
counter++
counterVal-= 2;
else
counter--;
counterVal+=2;
I'm 100% sure the teacher wants you to use a algorithm to solve this not just echo it out.. or u will get a low joe..
Anyways if you can't do this in a algorithm then u shouldnt be programming

| Code: | #include <iostream>
const int width_max = 10;
int width = 10;
int count = 0;
int main(){
do{
int difference = (width / 2) - 1;
for(int i = 0; i < difference; i++){
std::cout << " ";
}width--;
for(int i = 0; i < (width_max - width); i++){
std::cout << "*";
}std::cout << "\n";
}while(width > 0);
return 0;
} |
I then realized I had not taken fractions into account, and that I was doing it a stupid way to begin with, got bored, and stopped. Don't feel like actually thinking for a few minutes now. 
edit: Figured it out woop.
| Code: | #include <iostream>
int main()
{
int size, count = 0;
std::cin >> size;
for (int i = 0; size > i; count++, size--){
for (int i = 0; size > i; i++){
std::cout << " ";
}
for (int i = 0; (2 * count) >= i; i++){
std::cout << "*";
}std::cout << "\n";
}
return 0;

That's not Java, but thanks for trying anyway.

Now this is spoon feeding. He's given you the code, now just convert it.
Surely you can tell where the loops are in that code etc.

I think you are missing the last half (this broke my head..., but with the help of your code, i figured it out at last...))
| Code: | #include <iostream>
int main()
{
int size, count = 0;
std::cin >> size;
for (int i = 0; size > i; count++, size--){
for (int i = 0; size > i; i++){
std::cout << " ";
}
for (int i = 0; (2 * count) >= i; i++){
std::cout << "*";
}std::cout << "\n";
}
count--;
for (int i = count; size < i; size++, count--){
for (int i = 0; size+2 > i; i++){
std::cout << " ";
}
for (int i = 0; (count * 2 -1) > i; i++){
std::cout << "*";
}std::cout << "\n";
}
std::cin.sync();
std::cin.ignore();
return 0;

Here's my old code, maybe someone of you recognizes it :D
| Code: | import java.util.Random;
import java.io.*;
class printtt {
public static void main(String[] args) {
/* Let's do one randomly */
Random generator = new Random();
int rand = generator.nextInt(50);
rand += 50;
/* And one by user input */
System.out.print("Width: "); /* Get the width */
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String wid[] = {null, "\u0049", "\u0044\u0049\u0044\u004E\u0027\u0054", "\u004D\u0041\u004B\u0045", "\u0054\u0048\u0049\u0053", "\u004D\u0059\u0053\u0045\u004C\u0046"};
try {
wid[0] = br.readLine();
} catch (IOException ioe) {
System.out.println("Error");
}
/* DO THE PRINTING */
for( int i = 0; i<rand; ++i) { int j = generator.nextInt(5) + 1; System.out.println(wid[j]); }
}
} |
/me waits some random stupid kid (hackersrule or something) who knows nothing to derep me with a reason "he did someone's homework!" :)
