Write an interactive program called “DISTANCE CONVERTER” that accepts the distance in millimetres / feet / miles / yards / kilometres and displays its equivalent in metres.

#include<stdio.h>
#include<conio.h>

void main()
{
    float distance_unit, distance_meter;
    int choice, cont = 1;
    clrscr();

    printf("\nDistance Converter\n");

    while(cont == 1)
    {
        clrscr();
        printf("\n1.Enter distance in Millimeters.\n");
        printf("\n2.Enter distance in Feet.\n");
        printf("\n3.Enter distance in Miles.\n");
        printf("\n4.Enter distance in Yards.\n");
        printf("\n5.Enter distance in Kilometers.\n");
       
        printf("\nEnter your choice: ");
        scanf("%d", &choice);
       
        printf("\nEnter distance: ");
        scanf("%f", &distance_unit);
       
        switch(choice)

                distance_meter = distance_unit / 1000;
                break;
            case 2:
                //1 meter = 3.28 feet
                distance_meter = distance_unit / 3.28;
