Chapter 9.1, Problem 1CE

To determine

To write a program which computes the distance between two given points.

Explanation of Solution

Given:

The required program needs to find the distance of two given points.

Calculation:

The following is the required BASICProgram-

10 INPUT “Enter the x-coordinate of first point”: $x_1$

20 INPUT “Enter the y-coordinate of first point”: $y_1$

30 INPUT “Enter the x-coordinate of second point”: $x_2$

40 INPUT “Enter the y-coordinate of second point”: $y_2$

50LET $d=sqrt((x_1-x_2)\times (x_1-x_2)+(y_1-y_2)\times (y_1-y_2))$

60 PRINT “The distance between two given points is”: $d$

70 END.

DRY RUN of the program:-

INPUT:

Enter the x -coordinate of first point

  $x_1=-5$

Enter the y -coordinate of first point

  $y_1=1$

Enter the x -coordinate of second point

  $x_2=7$

Enter the y -coordinate of second point

  $y_2=3$

OUTPUT:

The distance between two given points is $d=12.165525$
