Encoder

[shing]

I made this python script with another guy a year ago

### This is a dictionary...
MyDict={'a':'$','b':'i','c':'q','d':'s','e':'w','f':'~','g':'d','h':'2',
        'i':'5','j':'6','k':'a','l':'g','m':'-','n':'j','o':'z','p':'%',
        'q':'h','r':'9','s':'f','t':'7','u':'+','v':'c','w':'0','x':'8',
        'y':'/','z':'x',' ':'*'}
 
## This is just to show the mapping of the 'encoding'
for k,v in MyDict.iteritems():
    print k,' will be encoded to.. ',v
 
## Here we ask for the word to be encoded
## Notice that i use the '.lower' method in case
##    the user inserts any uppercase letters
 
Word=raw_input("What is the word you want to encode?").lower()
 
## This is an empty string to begin with
Encoded_Word=''
 
## Now we iterate over the inserted word to check each letter
for letter in Word:
    if MyDict.has_key(letter):
        ## Insert to the string the coresponding character..
        Encoded_Word=Encoded_Word+MyDict.get(letter)
 
## Print the encoded word
print Encoded_Word
 

How do you make a dictionary in C++? And how do I make this script in the same format for a C++ program? I've tried in a very unethical and unlogical manner :P

//Encoder

  return 0;

While I would recommend using a data structure from the standard template library, I think the most equivalent structure would be a hash map.

However, depending on exactly what you are doing, that may not be the best choice for you. But it looks like the encoding is a static 1 to 1 replacement cypher, so it should work.

I don't quite understand the Standard template library. :(

This is what I have currently:

#include <iostream>
 
using namespace namespace_name std::map;
{
  int <key_type, data_type, [comparison_function]>;
  int <string, char> encoder;
 
}
 
std::map <key_type, data_type, [comparison_function]>;
 
std::map <string, char> encoder;
 
encoder["a"] = '*',
encoder["b"] = 'f';
encoder["c"] = '[';
encoder["d"] = 'p';
encoder["e"] = ']';
encoder["f"] = '\';
encoder["g"] = 'm';
encoder["h"] = 'z';
encoder["i"] = 'n';
encoder["j"] = '-';
encoder["k"] = '_';
encoder["l"] = ',';
encoder["m"] = 'W';
encoder["n"] = '`';
encoder["o"] = '~';
encoder["p"] = '&';
encoder["q"] = 'i';
encoder["r"] = 'x';
encoder["s"] = '^';
encoder["t"] = '+';
encoder["u"] = 'j';
encoder["v"] = 'q';
encoder["w"] = '9';
encoder["x"] = '4';
encoder["y"] = '.';
encoder["z"] = '=';
 
int main ()
 
{
         int a;
 
         cout << "Encoded word?";
         cin >> a;
 
         cout << "Encoded word is " << a;
 
         return 0;
 
}

Our resident oracle, weaknessforcats, just posted something that may help you in this thread.

Edit- This is assuming that you are understanding the language after your jump from Python. If you are looking for a more language-specific, C++ for programmer's type reference, post again and I'm sure we (by which I mean weaknessforcats as I have yet to see the limits of his knowledge) can come up with something.
