    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;

    			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

    You're SOL...start earlier next time.

    Don't they not teach unit testing anymore?
    Code:
    void test()
    {
        //convertintopig() test vectors
        char t1[][17] = {"is","by","girl","Blue","The","black","cat","ate","the","mouse","by","a","pond"};
        char a1[][17] = {"isway","byway","irlgay","Ueblay","Ethay","ackblay","atcay","ateway","ethay","ousemay","byway","away","ondpay"};
    
        //translateline() test vectors
        char t2[][100] = {"The black cat ate the mouse by a pond.",
                          "My friend: John Smith ,the cat."};
        char a2[][100] = {"Ethay ackblay atcay ateway ethay ousemay byway away ondpay.",
                          "Myway iendfray: Ohnjay Ithsmay ,ethay atcay."};
    
        int size,n;
        
        //convertintopig() test
        size = sizeof(a1)/sizeof(a1[0]);
    
        for (n = 0; n < size; n++)
        {
            char t[17],a[17];
            strcpy(t,t1[n]); //convertintopig() will modify the source
    
            convertintopig(t,a);
    
            if (strcmp(a,a1[n]) != 0)
            {
                printf("convertintopig() is broke, %s -> %s, should be %s\n",t1[n],a,a1[n]);
            }
            else
            {
                printf("convertintopig() %s -> %s, passed\n",t1[n],a);
            }
        }
    
    
        //translateline() test
        size = sizeof(a2)/sizeof(a2[0]);
    
        for (n = 0; n < size; n++)
        {
            char pl[200]={0};
    
            translateline(t2[n],pl);
    
            if (strcmp(pl,a2[n]) != 0)
            {
                printf("translateline() is broke, \n\"%s\" \n->\n\"%s\"\nshould be\n\"%s\"\n",t2[n],pl,a2[n]);
            }
            else
            {
                printf("translateline() passed\n");
            }
        }

    That test function will expose all your bugs...get it so all the tests pass.

    I'll go ahead and give a few:
    - "pw[a]=pl[pp];" - wrong
    - "memmove(ew,&ew[y],m-y);" - wrong
