Question

Create a typedef called timeType and a struct called timeType_struct with 3 components: an integer hr, an integer min, and an integer sec

Create a typedef called tourType and a struct called tourType struct with 3 components: a 50 character city name, an integer distance, and a travel time of type timeType.

Write a void function that takes a pointer parameter to a tourType struct as input and prints it.

Write a value-returning function that prompts for all the data in a tourType and returns a value of tourType.

Create a 3 element array of tourType

Use your function to read the data into structs in the array.

Once the array is populated, find the tour with the shortest distance and use your function to print it.

For Example:

Enter tour data for 3 cities...
Enter a city name: Chicago
Enter an integer distance: 300
Enter travel time as HH:MM:SS 06:00:01
Enter a city name: Pittsburgh
Enter an integer distance: 600
Enter travel time as HH:MM:SS 10:30:00
Enter a city name: Miami
Enter an integer distance: 500
Enter travel time as HH:MM:SS 08:00:00

Shortest Tour
-------------
City name: Chicago
Distance: 300
Travel time: 06:00:01
