Question

programming in Microsoft visual studio.

Write a C++ program for the following algorithm. Compile, run, and verify the result by choosing some test data.
Prompt user to write X1 value in double
Read X1
Prompt user to write X2 value in double
Read X2
Prompt user to write Y1 value in double
Read Y1
Prompt user to write Y2 value in double
Read Y2
Compute the lengths of the two sides of the right triangle generated by the two points
Compute the distance between the two points, which is equal to the length of the hypotenuse of the triangle.
Display the distance between the two points    

Answer 1

Program:-

#include<iostream>
#include<math.h>
using namespace std;
int main(){
double X1, X2, Y1, Y2, len1, len2,distance;
cout<<"Enter value of X1"<<endl;
cin>>X1;
cout<<"Enter value of X2"<<endl;
cin>>X2;
cout<<"Enter value of Y1"<<endl;
cin>>Y1;
cout<<"Enter value of Y2"<<endl;
cin>>Y2;
if(X1>X2){ len1=X1-X2;
}
else{
len1=X2-X1;
}
if(Y2>Y1){
len2=Y2-Y1;
}
else{
len2=Y1-Y2;
}
distance=sqrt(len1*len1+len2*len2);
cout<<"The distance between the two points is "<<distance;
}

You can verify this program by giving different values to points

For eg, if X1=0, X2=3, Y1=0, Y2=4

Then the distance between points (0,0) and (3,4) is 5
