Thread: problem with function

Hi, everything running smooth but there is 1 mistake cuz my output is always 0.00000

The function should basically return the distance between the points
idk whats wrong tho.

Thanks for any advice!

Code:

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


//Distance funktion


double distance(double x1, double y1, double x2, double y2, double erg1){
				return sqrt(pow(x2,-x1)+pow(y2,-y1));
}


int main()


{
double x1,y1,x2,y2,erg1;


printf("x1 y1 x2 y2");
scanf("%lf %lf %lf %lf",&x1,&y1,&x2,&y2);
printf("The distance is %lf", distance);
return 0;


}
