Simple C Program to Find the Length of a Straight Line

      Using this program user can find the length of a straight line formed by two end points, whose coordinates would be given as inputs.

FORMULA:-√ (( y2− y1)² +( x2− x1)²)

Program:

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

float x1,x2,y1,y2,line_len;

clrscr();

printf("Enter the x co-ordinate of the first point");

scanf("%f",&x1);

printf("Enter the y co-ordinate of the first point");

scanf("%f",&y1);

printf("Enter the x co-ordinate of the second point");

scanf("%f",&x2);

printf("Enter the y co-ordinate of the second point");

scanf("%f",&y2);

line_len=sqrt((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1));

printf("the length of the line is %f",line_len);

getch();

}

Output:

Algorithm:

1. Start
2. Define x1,x2,y1,y2,d
3. Accept the value of x1,y1,x2,y2
4. Calculate
5.     d=sqrt((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1))
6. Print value of d
7. Stop
