I need two function for the code above please support me

the function are called playerOturn and playerXturn which allow to the user to make a choice furthemore th

char square[9] = { '0','1','2','3','4','5','6','7','8' }; is declared inside the do while loop please help me to declare outside the while but I want to make sure that will be declared as local variable

this is a C++ code

thank you
