Question

IN C++ LANGUAGE PLEASE:::

Distance calc. This question is fairly straightforward. Design (pseudocode) and implement (source code) a program to compute the distance between 2 points. The program prompts the user to enter 2 points (X1, Y1) and (X2, Y2). The distance between 2 points formula is: Square_Root [(X2 – X1)^2 + (Y2 – Y1)^2]

Answer 1

PSEUDO CODE:

1. enter first point : (x1,y1) and second point: (x2,y2)
2. calculateDistance( x1,y1,x2,y2):
i) find difference of the x co-ordinates and square them  (x2-x1)^2
ii) find difference of the y co-ordinates and square them  (y2-y1)^2
iii) find sum of (i) and (ii).
iv) find square of the sum found in (iv)
3. print the distance calculated.

c++ code

#include <iostream>
#include <cmath>
using namespace std;
float calculateDistance(float x1, float y1, float x2, float y2)
{
   return sqrt(pow(x2 - x1, 2) + pow(y2 - y1, 2)); // Square_Root [(X2 – X1)^2 + (Y2 – Y1)^2]
}
int main()
{
   float x1,y1,x2,y2;
   cout << "\n Enter the first point:\t";
   cin>>x1>>y1;
   cout << "\n Enter the second point:\t";
   cin>>x2>>y2;
   float distance = calculateDistance(x1,y1,x2,y2);
   cout << "\n Distance between ("<< x1 <<"," <<y1<<") and ("<< x2 <<"," <<y2<<") is : "<<distance<<"units."<<endl;
   return 0;
}

/* OUPUT :

Enter the first point: 2 4

Enter the second point: 5 6

Distance between (2,4) and (5,6) is : 3.60555units.
