Thoughts on this code and improvement ideas

Sir_Spritely · 2003-08-05T18:21:07

I am currently getting stuck into C++, I have a programming background so doing the really basic simple stuff is straight forward. For a project I have written a simple Tic Tac Toe game just using functions and basic stuff. The next phase in my evil plan is to take this code and apply more advanced techniques such as pointers etc. Although I understand the more advanced techniques I have had problems implementing them and using them in a problem. I was hoping first off I could get some feedback on the current code, such as just how dreadful is it in the harsh reality of real life? Also some vague ideas to plant a seed so I can get stuck into revamping the code using more advanced techniques. Help appreciated. //----------------------------------------------------------------------------------------------- // Name: Standard.ccp // // Desc: This is simply the main .cpp file for whatever project happens to be in here today. // // Copyright (c) 2003, Paul Kirkbride. //----------------------------------------------------------------------------------------------- //----------------------------------------------------------------------------------------------- // Includes //----------------------------------------------------------------------------------------------- #include <stdafx.h> #include <iostream.h> #include <stdlib.h> // This is used for the rand() function //----------------------------------------------------------------------------------------------- // Name: Function Prototypes //----------------------------------------------------------------------------------------------- void OnePlayer(); void TwoPlayer(); void GameRules(); int RandomNUM(); int RandomNUM1(); //----------------------------------------------------------------------------------------------- // Name: main() // Desc: This is the main entry function for the entire program. //----------------------------------------------------------------------------------------------- int main() { int menuChoice = 0; while (menuChoice != 1 || 2 || 3) { cout << "\n\n-------------------------------------------------------------" <<endl; cout << " T I C T A C T O E V0.1 (c) Paul Kirkbride 2003 " <<endl; cout << "-------------------------------------------------------------" <<endl; cout << " G A M E M E N U " <<endl; cout << "-------------------------------------------------------------" <<endl; cout << "1.

quote:I didn''t look at any of the specifics, but I must say you have good commenting habits,

The only good commenting habit is "write code whose purpose and mechanism is so clear that it needs no comments".

Source code doesn''t lie. Comments do. Source code is always superior.

char a[99999],*p=a;int main(int c,char**V){char*v=c>0?1[V]:(char*)V;if(c>=0)for(;*v&&93!=*v;){62==*v&&++p||60==*v&&--p||43==*v&&++*p||45==*v&&--*p||44==*v&&(*p=getchar())||46==*v&&putchar(*p)||91==*v&&(*p&&main(0,(char**)(--v+2))||(v=(char*)main(-1,(char**)++v)-1));++v;}else for(c=1;c;c+=(91==*v)-(93==*v),++v);return(int)v;}  /*** drpizza@battleaxe.net ***/
