C :: Calculates Area Of A Triangle - If Statement
Jun 10, 2013I 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>

C++ :: Calculating Area Of A Triangle Using Heron Formula
Nov 7, 2014I 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.

C++ :: Find Area Of Room In A Given Square Maze
Apr 1, 2013Area 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.

I think the error is the changing value of x after a round of for loop.
C/C++ :: Program That Uses The Radius To Get Area?
Apr 28, 2012How can i come up with a program that uses entered radius of a circle to find its area
View 1 Replies View RelatedC++ :: Right Triangle Program Using X And Y
Jan 12, 2015I 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.

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;

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?
