Write a c program to calculate the distance between two points using formula √ (( y2− y1)² +( x2− x1)²)

#include<stdio.h> #include<math.h> int main ()      {         int  x1, x2, y1, y2;         float  r;         printf( "Enter Point (x1,y1): " );         scanf( "%d" ,&x1);         scanf( "%d" ,&y1);         printf( "\nEnter Point (x2,y2): " );         scanf( "%d%d" ,&x2,&y2);         r = sqrt(pow((y2-y1),2) + pow((x2-x1),2));         printf( "\nDistance= %f" ,r);         return  0;      }
