Help with c program that will have a system pause at the end.

1. Program to compute the car insurance premium for a person based on their age and the number of tickets they have received. The following table explains how to perform the ticket computation:

If Person's Age Is:

Then Insurance Cost Is-

Less than 21

$1500 + $250 x number of tickets

From 21 through 24

$1200 + $250 x number of tickets

25 or older

$1000 + $200 x number of tickets

Print the persons age, number of tickets and the computed insurance cost.

2. Write a program to compute the Mileage given by a vehicle.

Mileage = (new_odometer old_odometer)/(gallons_gas)

Program illustrating how for loop works.

3. Program to find the factorial of a number using recursive function
