The program prompts the user to input a

string of letters $($a$-$z$),$ with a maximum length of $50.$ Your program must read these characters into an

array, and then perform the following tasks on the array:

$1.$ Count the number of $\text{'}$t$\text{'}$s in the array.

$2.$ Change every third character to a $\text{'}$w $\text{'}.$

Lastly, your program should print the string, skipping over all remaining spaces.

$$ No asterisk $*$ should appear in your code. You are expected to use indexing instead of

pointers.

Three examples are provided below as the three examples work for both Part $1$ and Part $2.$

Part $2-$ Pointers:

Please check the starter code array$\_$vs$\_$ptr$\_2.$c and complete it$.$ The program performs exactly the same

as the program from part $1$ but with the following different requirements:

$$ No square brackets $[]$ should appear in your code. You are expected to use pointers instead

of indexing.
