Capitalization help

Ok, I need to write a program that capitalizes the first letters of a given sentance.
I am completely lost doing this.
I just need a kick in the right direction if someone could help.

if you want to just capitalise the first letter of the sentence then do this:

Code:

---

#include <ctype.h>

void Capitalize(char* sentence)
{
  if(sentence && strlen(sentence) > 0)
  {
    sentence[0] = toupper(sentence[0]);
  }
}

---

if you need to do the first letter of every word in the sentence then do this:

Code:

---

#include <ctype.h>

void Capitalize(char* sentence)
{
  int i = 0;
  int length;

  if(sentence && strlen(sentence) > 0)
  {
    length = strlen(sentence);
    while(i < length)
    {
        if(sentence[i] == ' ' && i < length - 1)
        {
            sentence[i + 1] = toupper(sentence[i + 1]);
        }
        i++;
    }
  }
}

---

hope this helps!
