The function will receive a character and it will print a

message indicating which function is running$$the if function or the switch$-$case

function. It will print the character that it received and then depending on the

character received it will use a single switch$-$case statement to do one of the

following operations. After completing the operations, it will print out the current

value of the character. $($The following operations are the same as in part $2.)$

a$.$ If the character is a lower$-$case letter and not an $$a$,$ convert it to an upper$-$case

letter.

b$.$ If the character is an upper$-$case letter and not an $$A$,$ convert it to a lower$-$

case letter.

c$.$ If the character is a digit, add $64$ to it$.$ Remember to print the character as

a character and not as an integer.
