Can anyone help with this C function?

Ok i had posted a help thing with this earlier, but everyone thinks im asking them to do the entire program for me. I got most of the program working but this section is confusing me a bit in the coding, if anyone could help me with ideas in the coding, im supposed to ask the user to enter a string of characters, and part of it is supposed to do what it says below with a made function.

1.Ensure that a space follows all punctuation (with the exception of the instances listed below)

No spacing around a dash (-)
No spacing around a quote (鈥?

2.Capitalize all text immediately following whitespace.

No spacing around a dash (-) but the following character is capitalized.

No spacing around a quote (鈥? but the following character is capitalized

I will assume that you have read a string into a buffer. You can pass that string to a function like this which will return a pointer to a string that has been converted to meet your requirements:


/* you will need to add error checking for buffer overrun if in is >2048 or whatever size you select for output */
#include "ctype.h"
char *enforce_rules( char *in )
{
char out[2048]; /* max size of converted */
char *op; /* pointer into output buffer */
int need_upper = 0; /* flagto indicate next char must be uppercase */
int need_space = 0; /* add space if next char is not */

op = out;
while( *in )
{
*op = 0;
if( ispunct( *in ) )
{
if( *in != '\'' && *in != '-' ) /* next must be space */
need_space = 1;
else
{
need_space = 0;
need_upper = 1;
}

*op++ = *in++; /* add character */
}
else
if( isspace( *in ) )
{
need_space = 0;
need_upper = 1; /* next must be upper */

*op++ = *in++;
}
else
{
if( need_space )
*op++ = ' '; /* add space if needed */
if( need_upper ) /* xlate to upper if needed */
*op++ = toupper( *in++ );
else
*op++ = *in++; /* copy char */

need_space = need_upper = 0; /* off flags */
}
}

*op = 0;
return strdup( out ); /* return a nice sized buffer; user must free */

}

--------- edit ------------
Forgot to set the need_upper flag if dash or quote encountered. Modified to add that.

for this you will need iostream.h to be included, and im "using namespace std;"

//
cout >> "Enter string of charaters";
char x;
cin << x;
//

this will prompt the user to input a value and then it will be stored in variable x. This is c++ so im not sure if it will work. But if you wish to applie those rules you listed so a user is not able to disobay them then you need to do that on your own because that will take about 60 lines of code, lol, have fun.
