Capitalize first letter of word

[romo14]

I'm working on a program that will take an address in on all one line separated by pounds (eg karen smith # p.o. box 123 # new york, new york #) and outputs it in user-friendly format. So far my program outputs:
karen smith
p.o. box 123
new york, new york

The only thing I can't figure out how to do is to capitalize the words that need capitalization. I know I need to use the toupper function and I think a for loop, but I don't know how to make it work. So far I have this:

int main ()
{
           cout << "Enter address: \n";
           char word[40];
 
           do {
                   read(word);
            } while(strcmp(word, "\n") != 0);
 
            return 0;
}
 
void read(char word[])
{
            cin >> word;
            if(strcmp(word, "#") != 0)
                     cout << word << " ";
            else
                     cout << endl;
}

Well, you'll probably need some specialized code for P.O., as it works differently from the others. Otherwise, you can toupper the appropriate letter as each 'word' will have the same general structure that needs capitalization.

How exactly would I use toupper in this case? I've looked all over the web but I can't figure out how to make it work properly.

[Laharl]

word[i]=toupper(word[i]);

As for using it, which letters in each token (besides P.O, that one's the exception) must be capitalized?

[romo14]

It should output like:
Karen Smith
P.O. Box 123
New York, New York

Since it's the first letter of every word, I know there is a way to get the first character after whitespace and capitalize that letter, I'm just not sure what it is.

I tried cin.get(word); and then for(int i=0;i<strlen(word);++i) word[i]=toupper(word[i]) but I it wouldn't compile so I'm pretty certain I'm doing something wrong.

Can you post the errors you are getting? As well as the lines of code the errors are pointing to (they are specified in the error message).

My grammar, spelling, and code may all be wrong!

If this were my problem i would start by writing the program below

#include <iostream>                 
using namespace std;
 
int main ()
{
  cout<<"a:"<<(int)'a'<<"\n"
      <<"z:"<<(int)'z'<<"\n"
      <<"A:"<<(int)'A'<<"\n"
      <<"Z:"<<(int)'Z'<<"\n"
 
  while(1){}
return 0;
}
 

output:

a:97    
z:122
A:65
Z:90

so we could assume
if a character were between 97 and 122 it
is lower case and if it were between
65 and 90 it upper case.

and looking at the numbers above it seems that
the following is true
(97-65 == 32) && (122-90 == 32)

so we can assume subtracting 32 would make a lowercase character a capital one
try out

  cout<<"A:"<< (char)((int)'a'-32);

edit:
i wanted to add a question for you;
is there a reason you are using c style strings? i would find it much easier to work with c++ style strings and maybe even a string stream
another edit:
i was just reading the original post you made. I had another suggestion. and that is to use some character other than '#' as a delimiter. Some people writing P.O. BOX # 120 or APT #2. Seems like pound might occur in the strings you are parsing. why not '|' or maybe '^' you have many choices.

<cctype> has functions for that, isupper() and islower(), that check if a character is an upper/lowercase letter.

i missed what he was actualy asking sorry.
