How to find triangle in an array of n triangles which has the largest area?
#include <stdio.h>
#include <stdlib.h>
#include<math.h>
typedef struct {
double x,y;
[Code] .....
i have written a program to find area of triangle, but i meet some errors,
//******area of triangle******//
#include<iostream>
using namespace std;
[Code].....
Thing I want is find the largest sum down a triangle,(moving to adjacent numbers on the row below )there are many methods to go down.

I wrote a program with a recursive() called finder. But it dose not work properly,at run time it becomes to a infinite status. How to detect the error at runtime. Here is the code.
#include<stdio.h>
void finder(int x,int y);
int tot;
[Code] ....
I think the error is the changing value of x after a round of for loop.
find inserted numbers, let say 10 numbers and find the largest and second largest number with their position in an array?

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
Code:
#include <stdio.h>
#include <math.h>
int main () {
float area, sideA, sideB, sideC, halfP;
[Code] ....
I need to calculate the area of a triangle using heron's formula. I wrote the code below and i need to modify it so that a user is required to keep entering the three side until he/she decides to stop. If the three sides entered make an invalid triangle, the user is required to re-enter the values until valid triangle is formed. Then the area is displayed.
#include <iostream>
#include <cmath>
using namespace std;
int main(){
double a,b,c=0;
double s,A=0;
[Code] .....
the screen output should like this:
Enter three sides of a triangle: 0 1 2 Error!
Re-enter three sides of a triangle: -1 1 2 Error!
Re-enter three sides of a triangle: 3 4 5 => 6
Continue (y/n)? y
Enter three sides of a triangle: 1 1 2 Error!
Re-enter three sides of a triangle: 6 8 10 => 24
Continue (y/n)? n
Done!
Please note that Continue (y/n)? only displayed after a valid triangle is formed. Otherwise, the user needs to re-enter sides until it's valid.
I have to write some cpp program which computes area of a triangle using cross product,we give 3 vertices as R2 and 3 edges as double.
I am beginning like this;
#include <iostream>
#include "R2.h"
#include <cmath>
using namespace std;
double area ( R2 *A,double *z)

Area of the room. Your task is to write a program that will find the area of room in a given square maze.
Note. Use recursion for solving this problem.
Input:
First line contains only one number N (3 <= N <= 10).The number that describes the size of the square maze.
On the next N lines maze itself is inputed ('.' - empty cell,'*' - wall).
And the last line contains two numbers - the row and column of the cell in the room those area you need to find.It is guaranteed that given cell is empty and that the maze is surrounded by walls on all sides.
Output:
Output only one number - total amount of empty cells in the selected room.
write a C++ program to find the area of a square, input the length of the side, and output your answer to the screen.

what's the ideal way to get an iterator to the item that has the largest key (int) smaller than a given value.
basically, the item before upper_bound(). I can use upper_bound() and then decrement, but it needs special cases for both end() and begin(), and in the case of end() I'm not sure how I get it to the last item in the map, afaik, we're not allowed to decrement end().
Code:
auto it = mymap.upper_bound(x);
if (it==mymap.begin()) // first item in the map is already too large. reject
NotFound();
else if (it==mymap.end())
[Code] .....
// here it points to largest item smaller than x.
I can iterate over the entire map and do a compare, but then I pretty much loose the benefit of the binary search.
I'm working on a silent auction program that will scan a file and find the highest from each group of bids, then have a running total of money made throughout the auction. I'm pretty sure the rest of my code works, i'm just getting stuck on finding the largest number from the line in the file, saving it, then moving to the next auction.
input file text (first number is num of auctions, after that it's num of bids, then the bids):
5 4 100 500 250 300 1 700 3 300 150 175 2 920 680 8 20 10 15 25 50 30 19 23
Sample Output
Auction 1 sold for $500.00!
Auction 2 sold for $700.00!
Auction 3 sold for $300.00!
Auction 4 sold for $920.00!
Auction 5 sold for $50.00!
The silent auction raised $2470.00 for charity!

How to find the largest and smallest number entered by a user. So far I'm able to add, find the average and count how many numbers are entered.
I'm just having trouble with find the max and min. I tried if statements and it breaks the program will it wont let me exit the while loop or the program will do a force close after entering a value.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(){
int maxNum=0, minNum=0, value, count=0, sum=0;
double average;

I made the code that stores and prints 5 row by 5 column values but how to find the largest number from them.What should I do to find the largest number?If I use if-else then it would be very tedious but I think there is way out with for loop but still I can't frame the logic. Here is the code

I seem to have reached a dead end in a program I am attempting to write.The purpose of the program is find the smallest, largest, and average values in a collection of N numbers. It needs to get the value of N before scanning each value in the collection of N numbers.I'm having trouble creating comparisons for each set. I have a feeling because of the way I structured my program, I'm unable to make a proper comparison. Maybe my approach was wrong as soon as I got to the for statement to loop N sets and N numbers.Here is my code so far:
Code:
#include <stdio.h>
int main (void)
{
int num_sets, num_of_integers;
int count, count2, set, sum = 0;
int num, avg;
}
[code]....
/* Here is where I would continue to attempt to make a comparison between sets to determine smallest to largest */
return 0;
I am writing this code, and I every time I run question A, no matter what numbers I put in, I get "larger = 0.
#include <iostream>
using namespace std;
int awesome ();
int best ();
int crazy ();
int main () {
char letter;
int smallestNumber;
int largestNumber;

Write a program that reads in a list of integers into an array with base type of int. Provide the facility to either read this array from the keyboard or from a file, at the user's option. If the user chooses file input the program should request a file name. You may assume that there are fewer than 50 entries in the array. Your program determines how many entries there are. The output is to be a two-column list. The first column is a list of the distinct array elements; the second column is the count of the number of occurrences of each element. The list should be sorted on entries in the first column, largest to smallest.
For example, for the input
-12 3 -12 4 1 1 -12 1 -1 1 2 3 4 2 3 -12
the output should be
N Count
4 2
3 3
2 2
1 4
-1 1
-12 4

i'm having trouble trying to make this code works .. the program must repeatedly asks user for the age of a person until user enters -1 ,, once he/she entered -1 the program calculates ( smallest value entered, largest value , and average )excluding -1 from calculation
i've been working on this for a weeks this is the best i could do.i know average must add all the entered values , not only smallest and largest but how can i do that here ?
Code:
#include<stdio.h>
int main(void)
{
int age ;
int v;
int counter;
int l=0;
int s=0;
int limit;

have traced the code line by line and it prints correctly up to line 31. However, when the program exits (line 35) , it goes to some other screen with very complex code and my output disappears.
Just to clarify: If I just run the code as is, there is no output. However, when I trace the code line by line, the output appears, but then disappears as the program exits My input was 1 2 3 4 5 6
