A mini game tic-tac-toe implemented in C.
To ask players to input tokens on the plate using the numeric keys. Since the 9 squares on the plate are marked with integers from 1 to 9 respectively, players need to input tokens by tapping numeric keys 1 - 9. The program should judge that player 1 or player 2 have won the game when 3 tokens with the same type are in a line. And the program should consider it as a draw when the 9 squares are filled with tokens but without the 3 same type tokens in a line. Besides, illegal inputs should be detected and reported, which are any inputs other than the integer numbers from 1 to 9. Repeated inputs are also considered as illegal and will be reported if input.
(Assume that the user only inputs valid data.)
Integer numbers from 1 to 9
Two kinds of tokens O and X in 9 squares separately
The same number cannot be chosen repeatedly
- Define 2 variables: row and column
row is assigned as 7 and it represents the numbers in a single row.
column is assigned as 3 and it represents the numbers in a single column. - Declare a series of functions and variables:
char p [row] [column] means declaring a 2D array of row*column.
int board(char p [row] [column]) means that the 2D array should be inserted into an assigned integer as the game board.
char order (int a) means that an integer a should be inserted into a character order.
int judge(char p [row] [column]) means that the 2D array should be inserted into an integer as a judgment basis.
int sum = 1 represents an integer assigned as 1.
int operate(char p [row] [column], int sum) means declaring a function operate with elements char p row column and int sum.
int x represents an integer x, which refers to a number in a single row, or the number of columns.
int y represents an integer y, which refers to a number in a single column, or the number of rows.
char s = 48 means assigning a character s as 48 according to ASCLL, which equals to 0 decimal.
int ch represents an integer ch.
int num = 0 means that the integer is assigned as 0. - Design an opening interface of the game.
- Build a single judging loop to guide players to start the game and lead to the main interface of the game.
- Print out the game board in the main interface using defined 2D array.
- Define the game rules about placing the tokens.
- Evaluate the logical judgments to define whether the game is a win, a lose or a draw.
- Detect and report if there is an illegal input.
