C Exercises: Calculate the distance between the two points

C Basic Declarations and Expressions: Exercise-15 with Solution

Write a C program to calculate the distance between the two points.
Note: x1, y1, x2, y2 are all double values.

Formula:

C Code:

#include <stdio.h>
#include <math.h>

int main() {
	float x1, y1, x2, y2, gdistance;
	printf("Input x1: ");
	scanf("%f", &x1);
	printf("Input y1: ");
	scanf("%f", &y1);
              printf("Input x2: ");
	scanf("%f", &x2);
	printf("Input y2: ");
	scanf("%f", &y2);
	gdistance = ((x2-x1)*(x2-x1))+((y2-y1)*(y2-y1));
	printf("Distance between the said points: %.4f", sqrt(gdistance));
	printf("\n");
	return 0;
}

Sample Output:

Input x1: 25                                                           
Input y1: 15                                                           
Input x2: 35                                                           
Input y2: 10                                                           
Distance between the said points: 11.1803
