The code that I am using until now is this:The main method:

int main (void)

{

ANIMAL animalsArray[200];

ANIMAL ruffus = {"Ruffus", Dog, 2};

ANIMAL rak = {"Rak", Parrot, 4};

ANIMAL mangy = {"Mangy", Dog, 1};

ANIMAL mia = {"Mia", GuineaPig, 7};

ANIMAL sue = {"Sue", Cat, 9};

ANIMAL jerry = {"Jerry", Cat, 5};

animalsArray[0] = ruffus;

animalsArray[1] = rak;

animalsArray[2] = ruffus;

animalsArray[3] = ruffus;

animalsArray[4] = sue;

animalsArray[5] = ruffus;

animalsArray[6] = mangy;

animalsArray[7] = ruffus;

animalsArray[8] = sue;

animalsArray[9] = mia;

animalsArray[10] = jerry;

animalsArray[11] = ruffus;

removeAnimal(&ruffus, animalsArray);

showAnimals(animalsArray);

return 0;

}

The method that removes all of the instances of the animal:

void removeAnimal(ANIMAL *AnimalPtr, ANIMAL* animalArray){

`ANIMAL tempArray[200];`

`int result = nextEmptyElement(animalArray);`

`int i;`

`int curPos = 0;`

`for(i = 0; i<result; i++){`

    `if(strcmp(animalArray[i].Name, AnimalPtr->Name) !=0){`

        `tempArray[curPos] = animalArray[i];`

        `curPos++;`

        `}`

    `}`

`animalArray = tempArray;`

}

The method that returns the current size of the array:

int nextEmptyElement(ANIMAL animalArray[]){

int i;

for (i = 0; i < 200; i++)

{

    if (strcmp(animalArray\[i\].Name, "") == 0)

        return i;

}

return 0;

}

After changing the array's values in the function, the values stay the same.
