How many bit strings of length fifteen

a) Contain at least four 0s?

b) Contain at most four 0s?

c)Contain exactly four 0s?

d) Begin with four 0s?

You are required to use only C for this problem.

To begin, instead of using two different variables for this problem, you are going to define a structure with two members; one representing the feet and the other one representing the inches. We will also use three functions; one to initialize a structure, one to check the validity of its values, and the last one to print them out.

First, define your structure. Next, declare a structure of this type inside main. Then, call your first function (the initialization function). This function will be of a type structure, it will receive zero parameters, and it will return a structure. Inside the function, you will ask the user for the height of the student. To clarify, you will use this function to initialize the structure you have in main.

After that, call a second function (the checking function). In this function, you will send your structure. The function will not return anything and it will validate the values inputted by the user. If any of the values is not in the right range (between 5’ 8” and 7’ 7” of the student height), your program will display an error message and your program will then exit. Oh and do make sure to also check for negative values. That'll be important.

With all that done, if the program didn’t exit, call the last function (the printing function). This function will receive a structure, it will not return anything and it will display the values of the two members of the structure. Good luck!

21.    Solve the problem.A 44-in. piece of string is cut into two pieces. One piece is used to form a circle and the other to form a square. How should the string be cut so that the sum of the areas is a minimum? Round to the nearest tenth, if necessary.  

a)Circle piece = 10.6 in., square piece = 33.4 in.
b)Square piece = 0 in., circle piece = 44 in.
C)Square piece = 10.6 in., circle piece = 33.4 in.
D)Square piece = 10.9 in., circle piece = 10.4 in.
