I have written here so far. The currently problem that I am facing is that I have no idea how I can write the MakeMove function. I am totally stuck and can't even think of a way to insert a move and not sure how I am going to insert move alternating Black player and Red Player and I am also confused how I am going to check whether if there's already a game piece in there or not. Can anyone help me?

After taking nothing more than a glance at your program I assume these answers will solve your problem:

1) "Insert" one of two players' colour in the board would be, for example, putting Board[j] = 1 for player 1 or = 2 for player 2.
2) Hold a variable Turn = 0 and increment it after every move. (Turn%2)+1 will tell you which player has to move
3) If Board[j]==0 then that slot is empty, otherwise it's occupied

Hope this helps :)

Think of the connect 4 as tic tac toe but different algorithm in finding the winner.

1-You would print the board
2-prompt player 1 for position on the board he wants
3-Let player 1 have 'X' and player 2 have 'O' or '1' or '2' or w/e character you want
print that character on to the position of the board
4-re print the board
5-check if winner - should check when the move count is reasonable to have a winner
6-prompt player 2 choice
7-reprint
8-check for winner

If you have a 4x4 board, you would have 16 slots.
Make an array of 16 integers instantiate them to -1 or 0
when either player inserts a move put a '1' or '2' to mark the players choice
that array would be used to check for winner and check to see which position is occupied.
