3). Recently New Delhi was reported as the most polluted city by WHO. Indian Govt came up with different measures to reduce the pollution, but nothing gave promising results as the city was heavily populated and long queues at every signal was considered normal. Finally Govt took firm decisions to reduce the traffic by allowing only restricted number of vehicles on road. It was decided to allow cars according to below rules. Sunday is considered as Day 1 and Saturday is considered as Day 7, and if last digit of your car plate matches Day number, you are allowed to use that vehicle on that day. Example: if your car plate number is 1341, you are allowed to use this vehicle on Sunday (Day 1) only. Plate numbers ending with 0,8,2 are allowed according to the formula,=> (Last Digit(as integer)+3)/2. Write a C if else ladder program to read the car plate number and find out on which days of a week a particular car plate number is allowed to travel, if length of car plate is maximum 4 digits.

Program:

#include <stdio.h>

int main()

{

int car_number;

printf("Enter the Car plate number:\n");

scanf("%d",&car_number);

int last_digit;

last_digit = car_number % 10;

if(last_digit == 0 || last_digit == 8 || last_digit == 9){

last_digit = (last_digit+3)/2;

}

if (last_digit == 1)

printf("Your car is eligible to use on Sunday\n");

else if (last_digit == 2)

printf("Your car is eligible to use on Monday\n");

else if (last_digit == 3)

printf("Your car is eligible to use on Tuesday\n");

else if (last_digit == 4)

printf("Your car is eligible to use on Wednesday\n");

else if (last_digit == 5)

printf("TYour car is eligible to use on Thursday\n");

else if (last_digit == 6)

printf("Your car is eligible to use on Friday\n");

else if (last_digit == 7)

printf("Your car is eligible to use on Saturday\n");

return 0;
