hello
Can u help me ?
write an java program that outputs the following pattern. The program shuold prompt the user an odd number of lines (limit 1 to 11) .
For example, if the user prompt the number of the lines is 9, then the output should be:
+
++
+++
++++
+++++
++++
+++
++

Jump to PostYou should find a formula for computing the withe spaces for each line and add it to the code.
Something like:
- for the longest line you need 7 "+" signs
- then for the first line you need 1 "+" sign and 3 spaces in the right side
- for the …

I tried this one, but there is some thing wrong >!
package javaapplication3;
import java.util.Scanner;
public class main {
public static void main(String[] args) {
Scanner read= new Scanner(System.in);
int count,i,number;
System.out.print("Enter the number: ");
number= read.nextInt();
if (number%2==0)
System.out.println(" Plz enter an odd number");
else
System.out.println(" The number is odd ");
count=1;
while (count<= number)
{
i=1;
while(i<=count)
{
System.out.print(count);
i=i+1;
}
System.out.println();
count=count+1;
}
count=(number-1);
while (count<=(number-1))
{
i=1;
while(i<=count)
{
System.out.print(count);
i=i+1;
}
System.out.println();
count=count-1;
}
}
}

while (count > 0){ // go backward
i=1;

// System.out.print(count);
System.out.print("+");
i=i+1;
}
System.out.println();
count=count-1;
}
}
anyway I hope I didn't just served the code to you and that you will understand what's modified

hi ,
I understand it ,, but if I want the pattern like this
...............+
.............+++
..........+++++
........+++++++
......... +++++
............+++
..............+
hoW i will do it ...?
WITHOUT THE DOTS.
Thanks So Much 4 helpinG ..
=)

You should find a formula for computing the withe spaces for each line and add it to the code.
Something like:
of course in your code, inside while loops you will use:
int space_characters = (number + 1) / 2 - count;
int plus_characters = count * 2 -1;
for (int k = 0; k < space_characters; k++)
System.out.println(" ");
for (int k = 0; k < plus_characters; k++)
System.out.println("+");or something like that ...
though you might not get the same pattern on screen because the width of the " " sign might be smaller than the one of the "+"
emm
how I do it ?
Plz , help me ...
I did not know how to do it . . ?
Try this:
public static void main(String[] args) {
Scanner read= new Scanner(System.in);
int count,i,number;
System.out.print("Enter the number: ");
number= read.nextInt();
if (number%2==0){
System.out.println(" Plz enter an odd number");
// here you should read the number again until it's odd or
// use System.exit() to exit the program
}
else
System.out.println(" The number is odd ");
count=1;
//while (count<= number){
while (count<= (number/2)+1){ // loop until you get to the middle number
int space_characters = (number + 1) / 2 - count;
int plus_characters = count * 2 -1;
for (int k = 0; k < space_characters; k++)
System.out.print(" ");
for (int k = 0; k < plus_characters; k++)
System.out.print("+");
}
System.out.println();
count=count+1;
}
//count=(number-1); // this will go into an infinite loop
//while (count<=(number-1)){ //since the counter will be always
// smaller then (number-1)
count = (number/2); // now starting from the middle
while (count > 0){ // go backward
int space_characters = (number + 1) / 2 - count;
int plus_characters = count * 2 -1;
for (int k = 0; k < space_characters; k++)
System.out.print(" ");
for (int k = 0; k < plus_characters; k++)
System.out.print("+");
}
System.out.println();
count=count-1;
}
}the firs part it give this pattern and the run does not stop .. !
+
+
+
and when i put the second part , it gives me an error for all . . !
package javaapplication47;
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner read= new Scanner(System.in);
int i,k, number;
System.out.print (" enter the number: ");
number= read.nextInt ();
i=1;
while (i<=number)
{
k=1;
while (k<=(number-i)){
System.out.print(" ");
k++; }
k=1;
while (k<=i){
System.out.print("+");
k++;}
k=i-1;
while (k>=1){
System.out.print("+");
k--;}
System.out.println();
i++;
}
}
}I do the first part ..
how I can inverse it ?
go backward from i = number -1;
while (i > 0)
and replace i++ with i--
i = number - 1;
while (i>0)
{
k=1;
while (k<=(number-i)){
System.out.print(" ");
k++; }
k=1;
while (k<=i){
System.out.print("+");
k++;}
k=i-1;
while (k>=1){
System.out.print("+");
k--;}
System.out.println();
i--;
}
}Thanx alot =)
