A smart city which is equipped with the latest technologies such as self-driving cars (SD), robots, UAV,and many others are shown in Fig.1. Consider a UAV which is deployed to monitor agriculture field andcommunicate with the robot, which can take an N number of different locations (A, B, C, and N) (referFig.1).Develop a C-script that calculates the distance between reference point R (1,3) of a UAV and robotlocations A, B, C, and N number of locations.N is the (non- zero) LSD of your mobile number.For 0 < LSD < 4 then take [N = (2LSD ) *2], and if LSD = 0, take [ N = (2LSD) *4+3]  

#include<stdio.h>
#include<math.h>
float distance();
int main()
{
    int num=0, i=0, a=0, b=0 ;
    float res;

    printf("Enter total no of locations: ");
    scanf("%d", &num);

    for(i=1;i<=num;i++){
        a = 0;
        b = 0;
        printf("\n\nEnter (x2, y2) for %d location: ",i);
        scanf("%d,%d", &a, &b);
        res = distance(a,b);
        printf("\nTotal distance between R(1,3) & (%d, %d): %f\n", a, b, res);
    }

    return (0);
}

float distance(int x2, int y2){
    // Base points
    int x1=1, y1=3;
    float t_d;
    t_d = sqrt(pow((x2-x1),2)+pow((y2-y1),2));
    return t_d;
