I have made a very simple tic tac toe game w/ comments but I cannot figure out how to make it so if player 1 picks a spot player 2 cannot pick the same spot. Any help would be greatly appreciated. #include//Header to allow input and output using cin and cout char a[1];// First section of tic tac toe board char b[1];// Second section of tic tac toe board char c[1];// Third section of tic tac toe board char d[1];// Fourth section of tic tac toe board char e[1];// Fifth section of tic tac toe board char f[1];// Sixth section of tic tac toe board char g[1];// Seventh section of tic tac toe board char h[1];// Eighth section of tic tac toe board char i[1];// Nineth section of tic tac toe board int ponemove; int ptwomove; ponewin();//Player ones winning message declaration ponewin(){//Player ones winning message code cout<<"Player one wins the game!!!\n"; } ptwowin();//Player twos winning message declaration ptwowin(){//Player twos winning message code cout<<"Player two wins the game!!!\n"; } getposition();//Get moves of both players declaration getposition(){//Get moves of both players code char a=''1'';//Setting board 1,1 to display 1 char b=''2'';//Setting board 1,2 to display 2 char c=''3'';//Setting board 1,3 to display 3 char d=''4'';//Setting board 2,1 to display 4 char e=''5'';//Setting board 2,2 to display 5 char f=''6'';//Setting board 2,3 to display 6 char g=''7'';//Setting board 3,1 to display 7 char h=''8'';//Setting board 3,2 to display 8 char i=''9'';//Setting board 3,3 to display 9 do{///////////////////////////Do While loop//////////////////// cout<<"\t\t************\n"; //Display cout<<"\t\t* "<>ponemove; if(ponemove==1){//if player 1 move = 1 assign x to a a=''x''; } if(ponemove==2){//if player 1 move = 2 assign x to b b=''x''; } if(ponemove==3){//if player 1 move = 3 assign x to c c=''x''; } if(ponemove==4){//if player 1 move = 4 assign x to d d=''x''; } if(ponemove==5){//if player 1 move = 5 assign x to e e=''x''; } if(ponemove==6){//if player 1 move = 6 assign x to f f=''x''; } if(ponemove==7){//if player 1 move = 7 assign x to g g=''x''; } if(ponemove==8){//if player 1 move = 8 assign x to h h=''x''; } if(ponemove==9){//if player 1 move = 9 assign x to i i=''x''; } if(a==''x''&&b==''x''&&c==''x''){// if combination of 3 is true{{{ ponewin(); return(0); } if(d==''x''&&e==''x''&&f==''x''){ ponewin(); return(0); } if(g==''x''&&h==''x''&&i==''x''){ ponewin(); return(0); } if(a==''x''&&d==''x''&&g==''x''){ ponewin(); return(0); } if(b==''x''&&e==''x''&&h==''x''){ ponewin(); return(0); } if(c==''x''&&f==''x''&&i==''x''){ ponewin(); return(0); } if(a==''x''&&e==''x''&&i==''x''){ ponewin(); return(0); } if(c==''x''&&e==''x''&&g==''x''){ ponewin(); return(0); } //}}} cout<<"\n\n\n"; cout<<"\t\t************\n"; //Same as above{ cout<<"\t\t* "<>ptwomove; cout<<"\n\n\n"; if(ptwomove==1){//Same as above except assigns o to variable{ a=''o''; } if(ptwomove==2){ b=''o''; } if(ptwomove==3){ c=''o''; } if(ptwomove==4){ d=''o''; } if(ptwomove==5){ e=''o''; } if(ptwomove==6){ f=''o''; } if(ptwomove==7){ g=''o''; } if(ptwomove==8){ h=''o''; } if(ptwomove==9){ i=''o''; } //}}} if(a==''o''&&b==''o''&&c==''o''){//IF any 3 combinations = x player 2 wins ptwowin(); return(0); } if(d==''o''&&e==''o''&&f==''o''){ ptwowin(); return(0); } if(g==''o''&&h==''o''&&i==''o''){ ptwowin(); return(0); } if(a==''o''&&d==''o''&&g==''o''){ ptwowin(); return(0); } if(b==''o''&&e==''o''&&h==''o''){ ptwowin(); return(0); } if(c==''o''&&f==''o''&&i==''o''){ ptwowin(); return(0); } if(a==''o''&&e==''o''&&i==''o''){ ptwowin(); return(0); } if(c==''o''&&e==''o''&&g==''o''){ ptwowin(); return(0); } ///}}}} } while(ponemove!=100);//END OF DO WHILE LOOP } main(){//Main Function getposition();//calls get position as defined above cout<<"TICK TACK TOE V 1.0\n";//Displays v # cout<<"BY:CORY FISHER\n";//Displays my name return(0);//Returns zero } Cory Fisher
