Write a program that reads from the user any three points in two dimensional space: x1, y1, x2, y2, x3, y3. Assume these points

netineya [11]

Answer:

The solution code is written in Python:

import math
coord= input("Enter coordinates for three points: ")
coordList = coord.split(" ")
for i in range(0, len(coordList)):
coordList[i] = float(coordList[i])
seg_1 = math.sqrt((coordList[0] - coordList[2])**2 + (coordList[1]- coordList[3])**2)
seg_2 = math.sqrt((coordList[2] - coordList[4])**2 + (coordList[3]- coordList[5])**2)
print(seg_1 + seg_2)

Explanation:

Firstly, we can use Python built-in method <em>input()</em> to get coordinates for three points from user (Line 3). To simplify the entry process, the input of the three coordinates is expected in a single string 0.0 0.0 3.0 4.0 6.0 8.0O. Please note each of the coordinates is separated by a single space.

Next, we can proceed to use Python string split() method and single space character " " as separator to break the input string of coordinates into a list of individual numbers ["0.0", "0.0", "3.0", "4.0", "6.0", "8.0"].

Prior to calculating the line segment, it is important to ensure the coordinates in the list,<em> coordList</em>, have been converted from string to float type (Line 6 - 7).

Next, we are ready to apply the Distance formula to calculate the length of the two line segments that join the three coordinates (Line 9 and Line 11). The distance formula is $\sqrt{ (x1 - x2){^2} + (y1 - y2){^2} }$

At last, sum up the two line segments, <em>seg_1 </em>& <em>seg_2 </em>and print it in the terminal (Line 13).

What are 2 main differences betweenarrays andstructs?

miv72 [106K]

Answer:

The two main differences between arrays and structures are as following according to me :-

1. Array is collection of data elements of same data type while a structure is collection of variables of different data types.

2.Array is a primitive data type while structure is a user defined data type.

There are other differences also which are as following:-

1. The size of array is fixed while the size of structure is not fixed as structure can contain different variables of different data types.

2.array is declared as following :-

int array [100];

where 100 is the size of the array means it can store up to 100 integer values.

struct class{

int roll_number;

char *name;

int admission_no;

};

3.Traversing and searching in an array is easy and fast while it is difficult and slow in structures.

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative intege

sveta [45]

Answer:

// Program is written in Coral Programming Language

// Comments are used for explanatory purpose

// Declare and input n; n stands for the number of input data

integer n

n = Get next input

// Declare and initialise two Variables to 0;

// The first Variable Sum, is used for addition and the second, Max is used for the max

integer sum

integer max

Sum = 0

Max = 0

// Declare and intialise Variable count to hold the number of positive input data

integer count

count = 0

// Declare array. The array is used to hold all input data

integer array(n) Arr

// Declare iterating variable I

integer i

//Use the following iterative statement to input array data

for i = 0; i < Arr.size; i = i + 1

Arr[I] = Get next input

if Arr[i] >= 0

Sum = Sum + Arr[i]

count = count + 1

if Arr[i] >= Max

Max = Arr[I]

// Declare Variable average

float average

//Calculate and print average

average = Sum/count

Put average to output

Put Max to output
