Function : play
--------------------------
Parameters: None
Local Variables
- x,y (float) set x, the value of 45; y, the value of 70
- btnWidth, btnHeight (int) set the btnWidth the value of 50; btnHeight
the value of 30
- freq[7][7] (int) set all the elements to zero
- str[20] (char)
- i,j (int)
- roll1, roll2 (int) used for rolling die 1 and 2
Steps:
1: Call srand with system time as seed – srand(time(NULL));
2: start for loop with initial value of i=0; condition of i<36000; increment as i++
3: set roll1, the value of 1+rand()%6 – to get a random number between 1 and 6
4: set roll2, the value of 1+rand()%6 – to get second random number between 1 and 6
5: switch (roll1)
6: case 1 update the array ++freq[1][roll2]; break;
7: case 2 update the array ++freq[2][roll2]; break;
8: case 3 update the array ++freq[3][roll2]; break;
9: case 4 update the array ++freq[4][roll2]; break;
10: case 5 update the array ++freq[5][roll2]; break;
11: case 6 update the array ++freq[6][roll2]; break;
12: end of for

start for loop with initial value of i=1; condition of i<=6; increment as i++ set x, the value of x+55
call draw_button with ColorGrey at position x,y with width btnWidth and height btnHeight
sprintf(str, "%d", i); – this is to convert the integer to string draw_text(str, ColorWhite, "arial.ttf", 15, x,y); - Writing text in the button
18:
19: Set x, the value of 45
end of for loop
25: end of for loop

31: Call draw_button with ColorYellow, x, y, btnWidth and btnHeight
32: sprintf(str, "%d", freq[i][j]);
33: Call draw_text with str, ColorRed, "arial.ttf", 15, x and y
34: end of for loop

After implementing the previous part extend your program so that the player wins the game only when the sum of diagonal elements are greater than 6000. You have to show a text box showing the sum as well as shown in the figure below.
Assume a[7][7] is your array
0123456 0
1 2 3 4 5 6
Submit the code and screen shot of the extended part.
Not using these red shaded arrays
