Write a program that performs the tasks described below.

$$ Define the following functions

void A$($char str$[])$ Takes string str and converts all non$-$letters to the $*$ character

in it$.$

Ex: $$a$1$b$2$c$$ becomes $$a$*$b$*$c$$

void B$($char str$[])$ Swaps the first half of str with the second half of str

Ex: $$abcxyz$$ becomes $$xyzabc$$

void C$($char str$[])$ Reverses the order of the characters in the first half of str$.$

Ex: $$abcxyz$$ becomes $$cbaxyz$$

void D$($char str$[])$ Reverses the order of the characters in the second half of str$.$

Ex: $$abcxyz$$ becomes $$abczyx$$

$($For the functions B$,$ C$,$ and D$,$ if the length of str is odd then the character in the middle of str

will not change.$)$

$$ Construct two arbitrary strings and print them on the screen. They can be at any length.

o The first one will be the string that will be manipulated by the functions above.

o The second one will contain a combination of letters A$,$ B$,$ C$,$ and D$.$ The order of

these letters in the second string represents the calling order of the related

functions.

$$ Send the first string to the first function. Then, the updated string will be sent to the next

function as a parameter. At each function call, the updated string should be printed on

the screen.

$$ The program should terminate after all the functions in the second string are called.

NOTES:

$$ If you need, you can implement other necessary functions in addition to the functions

above.

$$ You cannot use any library functions other than printf$()$;
