Jack and Poy using Goto Statement??

[garybone]

#1 Hi.. so this is my jack n poy game. In the end of the program/round the computer will ask if i want to continue of not(exit). Some says use goto statement but i'm not aware of that goto statement and other says never ever use goto statement. So what should i do?? Any hint???

Do you want to continue the game?Y/N:

if Y(Yes)
the program will start again. Then if N(No).the programs end. Thnx..

#2 Additional problem is in the line 43. What if every round is tied then such time it is exactly 1000000?? But i think it is not posible.. But can anyone give me another way of it.. that when someone's score is 0 the game is done and no need of range like 1000000.

#3 Another is: any hint of keyboard symbols of rock??? hahah i made a circle to illustrate it.. any other???

#4 When i type an any key except numbers the program will infinite loop..

Enter your choice (1)Rock (2)Paper (3)Scissors: ;

But it's not a big deal, i will make an instruction of the game that 1,2,3 is only the key to press when choosing.
but any hint???

Oh, it is about "goto statement". Very different thing from "gotoxy function".

Goto statement is something like:

repeat:
//...
if (userResponse == 'Y') {
    goto repeat;
}

While "gotoxy" function is just the function to position cursor on the screen. Its only problem is that it is not standard, though I do not think it should trouble you much now.

[garybone]

I actually get it before I read your response but thank you very much for your effort :)


can you help me with the problem #4???

[rodiongork]

Do not care about #4 right now - you will found it yourself bit later. Currently it is more important to you to learn splitting program into smaller functions (and use indentation). I encourage you to read something on this since it will greatly help you. :)

[garybone]

Thanks a lot bro :) Where can i read some of that topics??
