When i set any 3 inputs length, the space should be move in right position. I try to fix the space move forward into 1 space, but don't know why it doesn't work. Specially, when the number is 4 or 5. The space didn't move 1 space.

static void Main(){
int i,j,k;

I am trying to write a program that will make a pattern of stars. The last line is really tripping me up. I have to make the code only using the printf("*"); printf(" "); printf("/n"); statements once. I want to accomplish this with a for loops and if statements.
It is supposed to look like this:
* - 5 spaces before *
* * - 4 spaces before *
* * * - 3 spaces before *
* * * * * * - 0 spaces before *
This is what I've tried so far:
main()
{
int i, j, k;
i=1;
j=1;

here are the links on codepad [URL]
I think my first approach is way off. But I think I am on to something in the second link. I'm trying to print the "*" and extra 2 times on the fourth line. In the second link the compiler appears to be ignoring the || operator. Is my syntax incorrect in the second attempt? How should I change my if statement to make this pattern work?
Write a for loop statement to print the numbers from 1 to 10 in reverse order separated by star :
10*9*8*7*6*5*4*3*2*1
i try to do it but it show me like this :
10*9*8*7*6*5*4*3*2*1*
how do i write to show me like the first one ?

I've been trying to make a function that prints a pascal triangle based on an integer n inputted.
I have to write a program to print pascals triangle and stores it in a pointer to a pointer , which I am not entirely sure how to do. I also have to write the file and read it, then create a binary file. Assignment is attached. I am not the best with programming and especially with pointers. I will post my code below.
Code:
#include <stdio.h>
#include <stdlib.h>
void writePascalTriangle(char *fileName, int heightOfTriangle, int **triangle) {
FILE *fp;

Consider a coordinate system for the Milky Way, in which the Earth is at (0; 0; 0). Model stars as points, and assume distances are in light years. The Milky Way consists of approximately 1012 stars, and their coordinates are stored in a file in comma-separated values (CSV) format one line per star and four fields per line, the first corresponding to an ID, and then three floating point numbers corresponding to the star location. How would you compute the k stars which are closest to the Earth? You have only a few megabytes of RAM.

What the heck is wrong with my logic? I just print a rectangle!!! I have played with thing for ever it seems. I thought the rotating part would be hard but now I find myself stuck.

I originally had the user input three different lengths and then used this to determine whether or not it was a right triangle.
if(c==sqrt(a*a+b*b)||a==sqrt(b*b+c*c)||b=sqrt(a*a+b*b))
Now it has to be modified in order to accept the input 2,2 4,4 and 6,8(only an example) and be able to find out if it is a right triangle. I was told that arrays were not necessarily the only way to go about it.
I need to find out neighbors of a triangle and loop it over entire unstructured grid. How to do it?. Cell numbers are random so I am unable to loop over all cells.

I expect to get 0 for triangle1, but I get some strange value...
Here is the result
Type x for point1 : 1
Type y for point1 : 1
Type x for point2 : 3
Type y for point2 : 1
Type x for point3 : 1

The perimeter of the triangle1 is : 2.82843

After trying to understand the problem i finally gave up. The problem requires me to calculate the sum of the biggest numbers in a triangle.

I doesn't give me the same result(26) if a change the order of the numbers in the triangle.
Similar to Pascal’s triangle, the difference triangle has some interesting properties that find applications in various fields of the natural and applied sciences. In simple terms, a difference triangle is a set of integers arranged in an inverted triangle where each inverted triangle triad has its lower element equal to the difference (absolute value) of the two elements in the upper row. A difference triangle can be created from a sequence of integers forming the uppermost row by iteratively taking differences between consecutive terms to form the next row until a single-element row is created.
Example Consider the sequence 5, 8, 13, 21, 34, 55 from the Fibonacci series as the uppermost row of the difference triangle. The difference between successive elements form a new set: 3 (= 8 – 5), 5 (= 13 – 8), 8 (= 21 – 13), 13 (= 34 – 21), and 21 (= 55 – 34). The process can then be repeated until there is only one element left giving the following difference triangle:
5 8 13 21 34 55
3 5 8 13 21
2 3 5 8
1 2 3
1 1

Problem Write a program that forms a difference triangle using a given series of numbers as topmost row.
Write a class called MyTriangle, which models a triangle with 3 vertices, is designed as follows. It contains:
1. The MyTriangle class uses three MyPoint instances as the three vertices.
2. Three private instance variables v1, v2, v3 (instances of MyPoint), for the three vertices.
3. A constructor that constructs a MyTriangle with three points v1=(x1, y1), v2=(x2, y2), v3=(x3, y3).
4. An overloaded constructor that constructs MyTriangle given three instances of MyPoint.
5. A toString() function that returns a string description of the instance in the format "Triangle @ (x1, y1), (x2, y2), (x3, y3)".
6. A getPerimeter() function that returns the length of the perimeter in double. You should use the distance() method of MyPoint to compute the perimeter.
7. Also write a test program (called main.cpp) to test all the functions defined in the class (example of a triangle: (-2, 1), (1, 3) and (3, -3)).
class MyTriangle {
MyPoint v1;
MyPoint v2;
MyPoint v3;

MyTriangle(int x1,int y1,int x2,int y2,int x3,int y3) {

So, I have created a class called "point" and i have 4 "point" objects. They only have 2 variables, x and y (their position). The first 3 points form a triangle and now I need to tell if the forth one is inside or outside. I have found some solutions but they involve heavy math (they are based on the sum of the angles or something like that). I want to know if there is any way to solve this only by using the distance between points. I have created a function which takes 2 "point" objects and returns a float value which is their distance.
Here is some code:
#include <iostream>
#include <cstdlib>

It seems that it's just missing a space (and therefore a setw and setfill), but I found 2 problems:
1. The space needs to not apply to the first line.
2. I can't get it to make a space before each row without making a space between each column.
My current code is:
#include <iostream>
#include <iomanip>
using namespace std;
int main ( ) {
int rows;
[Code] ....
I have tried putting in << setws and << setfills of various values but it seems to always apply to between each column as well as at the start of each row- what do I do?
I have a program that prints out pascal's triangle. One problem: it isn't a triangle. The output doesn't work. This is what it should print:
Code: How many rows: 4
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1 and this is what it does print: Code: Enter a number of rows: 4
1
1 1
1 2 1
1 3 3 1

I am currently learning "if statements" while doing a program that calculates the area of a triangle. My problem is that the result is always "0". I am pretty sure the problem lies within my math, but how I have set it up wrong.
I am using Heron's Formula. Here it is for reference:
area=sqrt(s(s-a)(s-b)(s-c)) where s=(a+b+c)/2

float area, sideA, sideB, sideC, halfP;
