Program should be done using C language and using Dev-C++

I need main manu as the following

MAIN MENU

(Thema1)

[a] Display Empty Chess Board

(Thema2)

[b] Check Validity of Chess Notation (we use K, E, Q, R, N, B , P.)

THE CELLS ARE a1, a2, a3, a4, a5, a6, a7, a8

b1, b2, b3, b4, b5, b6, b7, b8

c1, c2, c3, c4, c5, c6, c7, c8

d1, d2, d3, d4, d5, d6, d7, d8

e1, e2, e3, e4, e5, e6, e7, e8

f1, f2, f3, f4, f5, f6, f7, f8

g1, g2, g3, g4, g5, g6, g7, g8

So valid moves are Ka1 to Ka8 or Kb1 to Kb8
or Kc1 to Kc8 or Kd1 to Kd8 or Ke1 to Ke8 or Kf1 to Kf8
or Kg1 to Kg8 also valid moves are all moves that K does by using Q, R, N, B or P

A user by pressing "v" gives for example Kb9 which is not valid move he will get a notation on screen "not valid move" . iF HE gives Kb2 then gets on screen "Valid move. Ok"

(Thema3)
[c] Save Moves to a Text File (This selection do the same as the previous but store the moves in a txt file)

(Thema4)

[d] Find Chess Moves in a String (user gives a char string of 30 characters. If he gives more the program keeps the first 30 and it finds valid moves from 30characters . The results should be displayed on screen )

(Thema5)

[e] End Program

Selection [d, v, s, f, e]:
