convert Num to Char**HELP PLS**

hi, when i add something to the code there are some error, can someone please let me know or if possbile please correct it for me by letting me know as i want to know what is wrong with the code....

when i run it the output is 66 62 12 15 28a s string, when i input Johnny.

my target is to convert those number of string to characters as i assign A is 00, B is 01....till.......Z is 26. if the number >= 26, for example 44 is larger so 44%26 = 18 so the character output will be S.

here is the code

Code:

    stringstream numbers;

/* Insert integer into stringstream*/
    numbers <<numLowerCaseLetter(name)<<sumAscii(name)<<lastValue<<counter<<sum;

/* Convert stringstream into string.*/
    string str = numbers.str();


    if(str.size() % 2 == 0)
    {
        for(int i = 0; i < str[i]; i=i+2)
        {
            numOfTwo[i]=str.substr(i,2);
            cout<<numOfTwo[i]<<" ";
        }
    }    
    else
    {
        
        str.size()+1;
        str.append( 1, '0' );
        
        for(int i = 0; i < str[i]; i=i+2)
        {
            numOfTwo[i]=str.substr(i,2);
            cout<<numOfTwo[i]<<" ";
        }    
        
    }  

// Final solution which convert number into character by producing a code.

 for(int i = 0; numOfTwo[i]; i++)
 {
     if(numOfTwo[i] >= 26)
     {
         modLeft = numOfTwo % 26;
         cout<< something[modLeft];
     } 
     else
     {
        cout<<something[numOfTwo[i]];
     }

when i run the code, this error comes out

In function `int main()':
could not convert `numOfTwo[i]' to `bool'
no match for 'operator>=' in 'numOfTwo[i] >= 26'
invalid operands of types `std::string[15]' and `int' to binary `operator%'
no match for 'operator[]' in 'something[numOfTwo[i]]'
syntax error before `{' token

if numOfTwo is an array of ints, then you can't assign a string to an int.

Code:

 numOfTwo[i]= str.substr(i,2);<<<this won't work!

try this instead

Code:

 numOfTwo[i]= atoi(str.substr(i,2).c_str());

Are you trying to do something like this?

Code:

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

int main()
{
   std::string text("Johnny");
   cout << text << " = ";
   for ( const char *ch = text.c_str(); *ch; ++ch )
   {
      // assume a character set with a contiguous alphabet, such as ASCII
      int value = toupper(*ch) - 'A';
      cout << value << ' ';
   }
   cout << endl;
   return 0;
}

/* my output
9 14 7 13 13 24
*/
