Create a program that converts the PRICE CODE to PRICE VALUE.

[whitegentle1]

Hello, I just wanted to help with my code
here's my questions

1. How can I input "computer" in any in any order and case insensitively and still get the correct output?

Here are the replacement
COMPUTERS.X
1234567890.X

2. If I input other letters that is not included in the COMPUTERS.X the program will terminate and ask again if i should input again.

example:

Input Code: Most.x
>UNABLE TO CONVERT YOUR INPUT

3. Is there any way to replace the whole string array instead of
``
replace(CODES.begin(),CODES.end(),'C','1');
``

#include <iostream>
#include <string.h>
#include <algorithm>

using namespace std;

int main()
{
    string CODES;
    char choice[5];
	
	do
	{
		cout << "Input code:  ";
		cin >> CODES;

	replace(CODES.begin(),CODES.end(),'C','1');
    	replace(CODES.begin(),CODES.end(),'O','2');
    	replace(CODES.begin(),CODES.end(),'M','3');
    	replace(CODES.begin(),CODES.end(),'P','4');
    	replace(CODES.begin(),CODES.end(),'U','5');
    	replace(CODES.begin(),CODES.end(),'T','6');
    	replace(CODES.begin(),CODES.end(),'E','7');
    	replace(CODES.begin(),CODES.end(),'R','8');
    	replace(CODES.begin(),CODES.end(),'S','9');
    	replace(CODES.begin(),CODES.end(),'X','0');
    	replace(CODES.begin(),CODES.end(),'c','1');
    	replace(CODES.begin(),CODES.end(),'o','2');
    	replace(CODES.begin(),CODES.end(),'m','3');
    	replace(CODES.begin(),CODES.end(),'p','4');
    	replace(CODES.begin(),CODES.end(),'u','5');
    	replace(CODES.begin(),CODES.end(),'t','6');
    	replace(CODES.begin(),CODES.end(),'e','7');
    	replace(CODES.begin(),CODES.end(),'r','8');
    	replace(CODES.begin(),CODES.end(),'s','9');
    	replace(CODES.begin(),CODES.end(),'x','0');
		
		cout << "Value: " << CODES << endl;
		
		cout << "Do you want to enter another code? (Y/N) ";
		cin >> choice;
	}
	while(strcmpi(choice, 'yes') == 0 ||strcmpi(choice, 'y') == 0 );
	{
        if (strcmpi(choice, 'no') == 0 || strcpmi(choice, 'no' == 0);
		{
        cout << "Program terminate";
		}
	}

	return 0;
}

any help will be appreciated, thank you very much

Maybe:

#include <iostream>
#include <cstring>
#include <cctype>

int main() {
	constexpr const char Codes[] {"computersxCOMPUTERSX"};
	constexpr const char Conv[] {"12345678901234567890"};
	unsigned char choice {};

	do {
		std::string code;

		std::cout << "Input code: ";
		std::cin >> code;

		for (auto& ch : code)
			if (const auto fnd {strchr(Codes, ch)}; fnd != nullptr)
				ch = Conv[fnd - Codes];
			else {
				std::cout << "Invalid input\n";
				code.clear();
				break;
			}

		if (!code.empty())
			std::cout << "Value: " << code << '\n';

		do {
			std::cout << "Do you want to enter another code? (Y/N) ";
			std::cin >> choice;
			choice = static_cast<unsigned char>(std::toupper(choice));

		} while (choice != 'N' && choice != 'Y' && (std::cout << "Invalid choice\n"));
	} while (choice =='Y');
}

[whitegentle1]

 In function 'int main()':
17:42: error: expected ')' before ';' token
17:42: error: could not convert 'fnd' from 'const std::initializer_list<const char* const>' to 'bool'
17:19: warning: unused variable 'fnd' [-Wunused-variable]
17:44: error: 'fnd' was not declared in this scope

i got this error

You need to compile for at least C++17. The latest standard is C++20.

What compiler/os are you using?

[whitegentle1]

devc++ ISOc++11 windows 11

[seeplus]

That code won't compile as C++11 - it needs at least C++17 as I mentioned above. If your compiler isn't at least C++17 compliant (and preferably c++20), then I suggest you update the compiler.

That code compiles OK with MS VS2022.

If that compiler can't be updated, then I suggest the free MS VS2022 community compiler https://visualstudio.microsoft.com/vs/

#include <iostream>
#include <string>
#include <cctype>
#include <map>
using namespace std;

int main()
{
   const string codesFrom = "COMPUTERS.X";
   const string codesTo   = "123456789.0";
   map<char,char> code;
   for ( int i = 0; i < codesFrom.size(); i++ )
   {
      char c = codesFrom[i], d = codesTo[i];
      code[tolower( c )] = code[toupper( c )] = d;
   }
   
   for ( char ans = 'y'; tolower( ans ) == 'y'; cin >> ans )
   {
      string word, drow;
      cout << "Enter word to be encoded: ";   cin >> word;
      bool ok = true;
      for ( char c : word )
      {
         auto it = code.find( c );
         if ( it == code.end() )
         {
            ok = false;
            break;
         }
         drow += it->second;
      }
      
      if ( ok )
      {
          cout << "Encoded: " << drow << '\n';
          break;
      }
      else
      {
          cout << "Unencodeable. Try again (y/n)? "; 
      }
   }
}

Enter word to be encoded: cow
Unencodeable. Try again (y/n)? y
Enter word to be encoded: cORe
Encoded: 1287

BTW The title of your post ... seems to have little bearing on what you are trying to do!

Even in the recent Embarcadero and Red Panda incarnations of the Integrated Development Environment (IDE) you won't be able to use any C++ standard later than C++11 even if the underlying compiler is capable of the later standard.

There are a couple of free C++ IDEs that are years ahead of Dev-C++: Visual Studio 2022 and Code::Blocks. VS uses MSVC++ compiler, C:B is available bundled with GCC/MinGW though it can use other compilers.

I have both, my personal preference is VS. Currently it is fully C++20 compliant, no other compiler is 100%.

Since you are using Windows 11 using Visual Studio would be a good bet. You'll have to do a custom install, C++ is not a default package.

you can use a map, but just using basic C constructs. Half the code is just a constant table.
the other half is simple and will work with C++ 1990s compilers if you trade out the string & RBFL. If you need it degraded back that far?

int main ()
{
 char tbl[256]{};
 tbl['c'] = tbl['C']='1'; 
 tbl['o'] = tbl['O']='2';
 tbl['m'] = tbl['M']='3';
 tbl['p'] = tbl['P']='4';
 tbl['u'] = tbl['U']='5';
 tbl['t'] = tbl['T']='6';
 tbl['e'] = tbl['E']='7';
 tbl['r'] = tbl['R']='8';
 tbl['s'] = tbl['S']='9'; 
 tbl['x'] = tbl['X']='0';
 tbl['.']='.';
 
 bool bad{false};
 do
 {
	 string in,out;
	 bad = false;
	 cout << "enter word\n";
	 cin >> in; 
	 for(char c:in)
	 {
		if(tbl[c])
		 out += tbl[c];
		else bad = true;
	 }
	if(!bad) cout << out << endl;
 }while(bad);
}

Thank you very much for your help, I found the solution for my prob. I've derived many codes to get fitted to my likes and downloaded visual studio for better compiling ooptions, im sorry im just a newbie

Here's some lessons on using Visual Studio to make transitioning easier.

https://www.learncpp.com/cpp-tutorial/installing-an-integrated-development-environment-ide/

The pictures show VS 2019, the process with VS 2022 is the same.

I recommend reading all of Learn C++'s chapter 0, and as you get comfortable with VS dive into the other lessons.
