I get inputs from user and I put them into a vector. After that I want to get any value of vector at some index. It gives a number. How can I get the exact input value?

enum Enums 
{
    I, O,T, J , L, S, Z
};

int main() 
{


  unsigned int index;
  Piece piece;

 
 
for (index=0; index < 5; index   )  
{
    cout << "What are the " << index 1 << ". piece?\n";
    cin >> piece.inputPiece;
    piece.pieceList.push_back(static_cast<Enums>(piece.inputPiece));
}
 Enums firstPiece= piece.pieceList[0];
 cout <<firstPiece;

}

Out Value is 79;

CodePudding user response：

One way to solve this is to fix the underlying type of the enum to unsigned char and also change the type of inputPiece to unsigned char as shown below:

//----------vvvvvvvvvvvvv---->fixed this to unsigned char
enum Enums: unsigned char 
{
    I, O,T, J , L, S, Z
};

class Piece  
{
public:
//--vvvvvvvvvvvvv------------->changed this to unsigned char
    unsigned char inputPiece;
    vector<Enums> pieceList;    
    
private:
 
};

int main() 
{
  unsigned int index;
  Piece piece;

 
 
for (index=0; index < 5; index   )  
{
    cout << "What are the " << index 1 << ". piece?\n";
    cin >> piece.inputPiece;
    piece.pieceList.push_back(static_cast<Enums>(piece.inputPiece));
}
 Enums firstPiece= piece.pieceList[0]; 
 cout <<firstPiece;//prints I for input I J T L S

}

Working demo.

The output of the program for the input: I J T L S is:

I
