name program

Let's say i typed in CHRIS
then i want the program to print out Chris
make lower case everyting except first letter of the name
ty

Code:

---

#include <iostream>
#include <string>
using namespace std;
char upper(char upper);
char lower(char lower);

int main(void)

{
        string first, middle, last, whole;\
        long number;

        cout <<"\nWhat is your name?\n ";

        cin >> first >> middle;

        if (cin.peek() != '\n')
        {
                cin >>last;
        }
        else
        {
                last = middle;
                middle = "";
        }
        cout << upper(last[0]);


        last = last.substr(1);

        number = 0;
        while (number < last.length())
        {
                last += lower(last[number]);
                number++;
        }



        //whole = last + ',' + first + ' ' + middle[0] + '.';
        cout << whole;





        return 0;
}

        char upper(char upper)
        {
                return toupper(upper);
        }

        char lower(char lower)
        {
                return tolower(lower);
        }

---

And what was the question?

how do i change big case to lower case?

this code is suppose to find all the charcters except first letter of the name
and change to lower case... but it doesnt work...T_T

Code:

---

  while (number < last.length())
        {
                last += lower(last[number]);
                number++;
        }

It seems to me you're modifying (and making longer) the same string that you're reading from.

Read from one string, and write to another.

This should do the trick:

Code:

---

int NameFormat(char* pszString, DWORD dwString)
{
  if(dwString < 1 || !pszString)
      return 1;
  if((pszString[0] >= 'a') && (pszString[0] <= 'z'))
      pszString[0] += ('A' - 'a');
  for(DWORD dwLoop = 1; dwLoop < dwString; dwLoop++)
      if((pszString[dwLoop] >= 'A') && (pszString[dwLoop] <= 'Z'))
        pszString[dwLoop] -= ('A' - 'a');
  return 0;
}

---

This should also do the trick:

Code:

---

#include <iostream>
#include <algorithm>
#include <cctype>

using namespace std;

//We have to wrap tolower so that transform can determine its type
char tolower_wrap(char c)
{
        return tolower(c);
}

int main()
{
        string foo("CHRIS");
        //Use transform to make each char after the first one lowercase
        transform(foo.begin()+1, foo.end(), foo.begin()+1, tolower_wrap);
        //Did it work?
        cout <<foo <<endl;
}

Phahch, mine is way more portable.

> Phahch, mine is way more portable.
Yours isn't portable at all with all that 'A'-'a' stuff. Would it work with EBCDIC?

At least using tolower() is an improvement.

Code:

---

char my_tolower(char c)
{
  char letters[52] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
  for(int i = 0; i < 26; i++)
  {
    if(c == letters[i])
    {
      return letters[i + 26];
    }
  }
  return c;
}

---

There you go. Completely portable.

Just to be contrary:
