Thread: pig latin help

Hi,
My assignment is on this website http://k4shif.netfirms.com/review.html
I have written the code, exactly like the pseudo code provided, and is heavily commented with my thought process....but for some reason it does not do its job....i am posting the code, any help will be greatly appreciated coz this is due tomm...once again thanks

Code:

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<ctype.h>

void translateline(char [], char []);
int extractintoew(char [], char [],int);
void convertintopig(char [], char [] );
int wherevowel(char []);
int copyintopl(char [], char [],int);

int main()
{
	char el[100]={'\0'},pl[200]={'\0'};
	int a=0;
	

	printf("Please enter a line(# to end): ");
	gets(el);

	while(el[0]!='#')
	{
		translateline(el,pl);
		puts(pl);

		

		printf("\nPlease enter a line(# to end): ");
		fflush(stdin);
	    gets(el);
	}

	printf("Good Bye. Oodgay Ebyay\n");
	system("PAUSE");
	return 0;
}

	int ep=0,pp=0,k=0,r;

	while(el[ep]!='\0')
	{
		if(isalpha(el[ep]))
		{
			k=extractintoew(el,ew,ep);
			ep+=k;//this is to keep everything at par, so even here, one behind space or punct
			convertintopig(ew,pw);//copies the contents of pw into pl, pp at this point is still 0
			r=copyintopl(pw,pl,pp);//this will return the value of pp, as to where it is in pl so that we can put the punct or space
			pp+=r;//now pp is set at before that point
			pp--;//now it is set for pp++
			pp++;//now ready to accept punct or space position
			ep++;//now at punct or space position
		}
		else
		{
			if(isspace(el[ep]))
			{
				el[ep]=pl[pp];
			}
			else
			{

				strcat(pl," ");//after punctuation put a space

	else
	{

		memmove(ew,&ew[y],m-y);// m-y indicates that number of alphabets to move
		strcat(ew,"ay");
