Question: This program should be done in C language. Use the program below to modify it to include multiple game modes; the two-player mode youve written
This program should be done in C language. Use the program below to modify it to include multiple game modes; the two-player mode youve written so far and a single-player mode. The user should select which game mode they want to play from a menu at the start of the program. The single-player mode should create a struct for the computer player that assigns it the name Computer and the letter O. The computer should make moves by picking the most top left place among all the available places in the board.
Use the following function prototypes:
void playSinglePlayer();
void playTwoPlayer();
void makeComputerMove(char board[][3]);
The output should look like this:
This is the program to modify:
#include
void initializeBoard(char board[][3]);
void displayBoard(char board[][3]);
void makeMove(char board[][3], char player);
int validMove(char board[][3], int row, int column);
int checkWinner(char board[][3]);
int main()
{
int moves = 1;
char board[3][3];
char player = 'o';
