Answer 1

int findHighest (int array[], int size)

{

int max = array[0];

for(int i=1; i<size; i++)

{

if(array[i] > max)

max = array[i];

}

return max;

}

int findFirstFail (int array[], int size)

{

int index = 0;

for(int i=0; i<size; i++)

{

if(array[i] < 50)

{

index = i;

break;

}

}

return index;
