Thread: Arrays: Passing Index of String Array to Index of Int Array for Output only

Hello, I am looking to pass the int values of an array to the indices of a string array "behind the scenes." I want the string arrays to be ouput with their strings, however I want to do math on the indices the strings represent.
In other words I would like to combine or blend them together so that I have 4 arrays: 2 of them are int arrays, 1 of the int arrays is for doing math on; and 2 of them are string arrays, both of them are for display to the screen purposes only.
If I try to loop through the int arrays and assign the string array elements to their corresponding indices, it won't compile, and I get the error message:
"Cannot convert 'std::string' to 'int' in assignment."
If I try to loop through the string arrays and assign them the int array values to their corresponding indices, it compiles, however I get the ASCII representation of the int values, rather than the numbers.
Here is the code for looping through the int arrays:

Code:

#include <iostream>	

using namespace std;
	
int main()			
{	
    
    int typeArray[4] = {55,66,77,88};
    int valArray[13] = {1,2,3,4,5,6,7,8,9,10,11,12,13};
    
    string types[4] = {"Manny", "Moe", "Jack", "John" };
    string values[13] = {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten",
                          "Eleven","Twelve","Thirteen"};
                          
    for (int i = 0; i < sizeof(typeArray)/sizeof(int); i++)
      {
        for (int j = 0; j < sizeof(valArray)/sizeof(int); j++)
        {
                
            typeArray[i] = types[0];
            valArray[j] = values[0];
            }
      }

      system("Pause");
      return 0; 
}

AGAIN, IT WON'T COMPILE, AND I GET THE ERROR MESSAGE NOTED ABOVE.
Here is the code for looping through the string arrays and the output:

Code:

#include <iostream>	

using namespace std;
	
int main()			
{	
    
    int typeArray[4] = {55,66,77,88};
    int valArray[13] = {1,2,3,4,5,6,7,8,9,10,11,12,13};
    
    string types[4] = {"Manny", "Moe", "Jack", "John" };
    string values[13] = {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten",
                          "Eleven","Twelve","Thirteen"};



    
        for (int i = 0; i < sizeof(types)/sizeof(int); i++)
         {
        for (int j = 0; j < sizeof(values)/sizeof(int); j++)
          {
                
            types[i] = typeArray[0];
            values[j] = valArray[0];
            
            cout << "This is types array: " << types[i] << "  This is values array: " << values[j] << endl;
          }
       }

      system("Pause");
      return 0;
}

------------------------
HERE IS THE OUTPUT SHOWING ASCII CONVERSIONS OF THE INTS:
This is types array: 7 This is values array: ☺

Please advise, thanks!

Hi uberfuzz,
Thank you for the suggestion. It might work in another program.
This program requires integer values in each index for the int array. I am going to do math on them, so they need to be ints.
I realize there is a "conflict" between strings and ints, however, this is similar to a deck of cards where the "Ace" is a string that is equal to the integer value of "-1".
Also, I already have a 2-Dimensional vector of both int arrays, so I'll be using a vector for the program which eliminates other options like maps. Let me know what you think, thanks!

Could you explain what you're going to do with the number/strings? I said something about math. A tree map should be able to do the things you explained in the first post... MK27 example is a solid way of mapping int to strings. I seem to remember doing a similar thing back in school when I had an assignment to do a symbolic calculator.

Eh, I wrote I said soomething when it should be you said something... (I couldn't fins the edit button.)

Hello uberfuzz and MK27!...I apologize for the late response, there were plumbing problems here, etc....etc....; p

Anyway, back to the fun, yes amigo(a)s...What my goal is, is to make a deck of cards. I omitted stating this originally because I've seen so much debate in various forums as to what's "the best way to do it." So, in answer to your questions, the math I am looking to do is on the card's values. I want to code the cards with ints for both the suits and the values. Why? So, that if I want to use this program later for poker where suits apply to the game, I can re-use the code. As for the values, Ace - King, definitely those are ints.

MK27, you say "maps are also dynamically resizable." Is this the same as a vector? The whole point of the vector is to be sure that no card is dealt twice until either the game is re-started, or the deck is completely dealt.

uberfuzz, you talked about a tree map, I don't think I'm there yet...; )....however, I aspire to it one day soon.....the symbolic calculator sounds mondo groovy.
As for spelling and editing, I try to follow Mr. Job's advice, "stay hungry AND foolish."

Now that I've "confessed," please advise, thanks!
