Write a C++ program that prompt the user to enter three points (x1, y1), (x2, y2), (x3,y3) of a triangle and displays its area.

maxonik [38]

Answer:

Here is the code in c++.

//include headers

#include <bits/stdc++.h>

using namespace std;

//main function

int main() {

//variables to store coordinates

float x1,x2,y1,y2,x3,y3;

cout<<"Please Enter the coordinate of first point (x1,y1): ";

// reading coordinate of first point

cin>>x1>>y1;

cout<<"Please Enter the coordinate of second point (x2,y2): ";

// reading coordinate of second point

cin>>x2>>y2;

cout<<"Please Enter the coordinate of third point (x3,y3): ";

// reading coordinate of third point

cin>>x3>>y3;

//calculating area of the triangle

float area=abs((x1*(y2-y3)+x2*(y3-y1)+x3*(y1-y2))/2);

cout<<"area of the triangle:"<<area<<endl;

return 0;

}

Explanation:

Declare four variables x1,x2,x3,y1,y2,y3 to store the coordinate of all three

points of circle.Read the coordinate of all the point from user.Calculate area of triangle with the help of mentioned formula area=abs((x1*(y2-y3)+x2*(y3-y1)+x3*(y1-y2))/2). Then print the area of the triangle.

Output:

Please Enter the coordinate of first point (x1,y1): 11 17

Please Enter the coordinate of second point (x2,y2): 23 30

Please Enter the coordinate of third point (x3,y3): 43 18

area of the triangle:202

Explain the concept of scalability. How would you respond?

pantera1 [17]

Answer:

In computer science, scalability is the ability of an application or product that could be software or software to continue responding well when its context is increased in volume or size to meet the user demand. Typically, when a product becomes aging or the context demands a rescaling to a larger size or volume, if the product is prepared to respond to this demand, then it's called a scalable product.

You are working for the census bureau and you need to write a program in C to do the following: a) count the number of people in

valina [46]

Answer:

See explaination

Explanation:

#include<iostream>

#include<stdio.h>

#include<conio.h>

#include<math.h>

using namespace std;

void main()

{

int RandomData[]={10,5,20,45,20,66,25,31,20,70}; //Random Data

int infant=0,young=0,middle=0,old=0,older=0; //To store count

int n,freq,count=0,high=0; //to store mode and other

double stdDev,mean,sum=0; //to store stdDev mean and sum

for(int i=0;i<(sizeof(RandomData)/sizeof(RandomData[0]));i++) //loop to count

{

if(RandomData[i]>0&&RandomData[i]<=18)

infant++;

else if(RandomData[i]>18&&RandomData[i]<=29)

young++;

else if(RandomData[i]>29&&RandomData[i]<=50)

middle++;

else if(RandomData[i]>50&&RandomData[i]<=69)

old++;

else if(RandomData[i]>69)

older++;

}

double first=0,sec=0; //to store result of stdDev formula first and second part

for(int i=0;i<(sizeof(RandomData)/sizeof(RandomData[0]));i++) //loop to calculate mean mode and stdDev

{

n=RandomData[i];

count=0;

for(int j=0;j<(sizeof(RandomData)/sizeof(RandomData[0]));j++)

{

if(n==RandomData[j])

count++;

}

if(high<count)

{

freq=RandomData[i];

high=count;

}

first+=(pow((RandomData[i]),2)/(sizeof(RandomData)/sizeof(RandomData[0])));

sec+=RandomData[i]/(sizeof(RandomData)/sizeof(RandomData[0]));

sum+=RandomData[i];

}

mean=sum/(sizeof(RandomData)/sizeof(RandomData[0]));

stdDev=sqrt(first-pow((sec),2));

/*------Printing Result-----*/

cout<<"\nCount:\nInfant: "<<infant<<"\nYoung: "<<young<<"\nMiddle: "<<middle;

cout<<"\nOld: "<<old<<"\nOlder: "<<older;

cout<<"\n\nMean: "<<mean<<"\nMode: "<<freq<<"\nStandard Deviation: "<<stdDev;
