question about pig latin help for a subfunction

C

I have no idea about how to do the part below
I am a new learner and I could not finish createPiglatinVersion part
thanks
create a Pig Latin version of the original string (may be several words, for the whole line of input) and save in another string --MAKE SURE YOU DON'T GO OUTSIDE THE ARRAY BOUNDS, and DON'T CHANGE THE ORIGINAL STRING! Be sure to copy the non-letters to the new string, and copy the pig-latin versions of the words in place of an input word to the new string

Here is the work I have done

<pre lang="cs">#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

#define FLUSH while (getchar() != '\n')

#define MAX_SIZE 256
#define WORD_SIZE 46

void getString (void);
void createPiglatinVersion(char *inputStr);
int getWord (char *inputStr,char *wordStr, int index);
void getPigLatin(char *temp, char *wordStr, int index);
bool isVowel(char oneword);
void printString(char *inputStr, char *outputStr);
bool repeatFcn(void);


int main (void)
{
    char oneword='y';
    printf("%d",isVowel(oneword));

    system("pause");
    return 0;
}

void getString (void)
{
     char inputStr[MAX_SIZE];

     printf("\nEnter a sentence (end with [Enter]):");
     fgets(inputStr, sizeof(inputStr), stdin);
     while (strlen(inputStr)>255)
          {
           FLUSH;
          }

}

void createPiglatinVersion(char *inputStr)
{
     char outputStr[MAX_SIZE];
     char temp[WORD_SIZE];
     char wordStr[WORD_SIZE];
     int index = 0;
     int i;

     for(i=0, i<MAX_SIZE, ++i)
          {
           outputStr
           getWord ( inputStr,wordStr, index);
           getPigLatin( temp,  wordStr, index);

          }
}

int getWord (char *inputStr,char *wordStr, int index)
{


     int i;
     for (i=0;i<WORD_SIZE&&isalpha(inputStr[index]);++i);
         {
          wordStr[i]=inputStr[index];
          index++;
          }
     wordStr[i]='\0';
     return index;
}

void getPigLatin(char *temp, char *wordStr, int index)
{
     if(isVowel(*wordStr)!=false&&isVowel(*wordStr+1))
         {
          strcpy(temp, wordStr);
          temp[strlen(temp)+1]='\0';
          strcat(temp,"ay");
          }
     else if(isVowel(*wordStr)!=false&& isVowel(*wordStr+1)!=false)
         {
          strcpy(temp,wordStr+2);//copy word starting from second character to temp
          temp[strlen(temp)]=*(--wordStr);//copy the first char of word to end of temp
          temp[strlen(temp)-1]=*(wordStr-2);
          temp[strlen(temp)+1]= '\0'; // Null terminate temp
          strcat(temp,"AY");          // append "AY" to the string.
          }
     else if(isVowel(*wordStr))
         {
          strcpy(temp, wordStr);
