C Cout Cin System Ambiguous

Question

I was just programming in c    when all of a sudden all the  cout s and  cin s were errors and  Ambiguous   Including System   I don t know why this happened  Everything was fine  I was coding the same program for about 2 hours  when it just    happened   EDIT  I can still run the program without errors  but they show as errors on the text  the red scribbly line  What happened   I m using the Visual Studio 2013 IDE  whatever it comes with    include  lt iostream gt   include  lt ctime gt   include  lt string gt   include  lt Windows h gt   include  lt cstdlib gt   include  lt stdlib h gt   using namespace std   int main      struct Gun       string name      int damage      int cost      bool purchased      bool equipped     M4A1  FAMAS     WEAPONS INFO M4A1 cost   50  M4A1 damage   5  M4A1 purchased   false  M4A1 equipped   false   FAMAS cost   300  FAMAS damage   10  FAMAS purchased   false  FAMAS equipped   false    WEAPONS INFO    -----PLAYER BEGIN -----  struct Player       int health      string name      int money      int energy       string l a      string r a      string l l      string r l       string rank     Player     GAME PLAYER BEGIN  Player l a    Normal   Player r a    Normal   Player l l    Normal   Player r l    Normal    Player health   100  Player money   100  Player energy   100   string plyrname  string rank    Private    Player name   plyrname     GAME PLAYER END    -----PLAYER END -----  cout  lt  lt   What is your name     cin  gt  gt  plyrname   goto mmenu    mmenu     -----MAIN MENU BEGIN ----- system  CLS    if  Player l a     Damaged         cout  lt  lt   Your Left Arm is damaged  Sleep for a while to fix it        Sleep 1600     if  Player r a     Damaged         cout  lt  lt   Your Right Arm is damaged  Sleep for a while to fix it        Sleep 1600     if  Player l l     Damaged         cout  lt  lt   Your Left Leg is damaged  Sleep for a while to fix it        Sleep 1600     if  Player r l     Damaged         cout  lt  lt   Your Right Leg is damaged  Sleep for a while to fix it        Sleep 1600       if  Player money  gt   500  amp  amp  Player rank     Private         system  CLS        cout  lt  lt   You have been promoted to Private 2        Player rank    Private 2       Sleep 1600       if  Player money  gt   1000  amp  amp  Player rank     Private 2         system  CLS        cout  lt  lt   You have been promoted to Private First Class        Player rank    Private First Class       Sleep 1600       system  CLS    cout  lt  lt   Health     lt  lt  Player health  lt  lt     Money     lt  lt  Player money  lt  lt    dollars    lt  lt      Energy     lt  lt  Player energy  if  M4A1 equipped      cout  lt  lt    nGun  M4A1   if  FAMAS equipped      cout  lt  lt    nGun  FAMAS    cout  lt  lt    n nRank     lt  lt  Player rank  cout  lt  lt    n n1  Go to Gunstore n2  Sleep n3  Fight n nAction     int mmenuch1  cin  gt  gt  mmenuch1   if  mmenuch1    1        goto gunstore     if  mmenuch1    2        system  CLS        cout  lt  lt   You sleep  restoring your energy        Player energy   100       if  Player l a     Damaged                 cout  lt  lt    n nYour Left Arm was healed            Player l a    Normal             if  Player r a     Damaged                 cout  lt  lt    n nYour Right Arm was healed            Player r a    Normal             if  Player l l     Damaged                 cout  lt  lt    n nYour Left Leg was healed            Player l l    Normal             if  Player r l     Damaged                 cout  lt  lt   Your Right Leg was healed                Sleep 1400       goto mmenu     if  mmenuch1    3        system  CLS        goto fight       -----MAIN MENU END -----   fight  srand time 0     system  CLS     if  Player r a     Damaged     Player r l     Damaged     Player l a     Damaged     Player l l     Damaged         cout  lt  lt   You re injured  sleep to heal        Sleep 1400       goto mmenu     if  Player energy  lt  40        cout  lt  lt   You don t have enough energy to fight        Sleep 1400       goto mmenu     if  M4A1 equipped    false  amp  amp  FAMAS equipped    false        cout  lt  lt   You don t have a gun equipped        Sleep 1400       goto gunstore     if  M4A1 equipped    true  amp  amp  Player energy  gt  40         int randnum1   rand      M4A1 damage -

This kind of thing doesn t just magically happen on its own  you changed something  In industry we use version control to make regular savepoints  so when something goes wrong we can trace back the specific changes we made that resulted in that problem   Since you haven t done that here  we can only really guess  In Visual Studio  Intellisense  the technology that gives you auto-complete dropdowns and those squiggly red lines  works separately from the actual C   compiler under the bonnet  and sometimes gets things a bit wrong   In this case I d ask why you re including both cstdlib and stdlib h  you should only use one of them  and I recommend the former  They are basically the same header  a C header  but cstdlib puts them in the namespace std in order to  C  -ise  them  In theory  including both wouldn t conflict but  well  this is Microsoft we re talking about  Their C   toolchain sometimes leaves something to be desired  Any time the Intellisense disagrees with the compiler has to be considered a bug  whichever way you look at it   Anyway  your use of using namespace std  which I would recommend against  in future  means that std  system from cstdlib now conflicts with system from stdlib h  I can t explain what s going on with std  cout and std  cin   Try removing  include  lt stdlib h gt  and see what happens   If your program is building successfully then you don t need to worry too much about this  but I can imagine the false positives being annoying when you re working in your IDE
