It's a start but you need to learn.

- these functions can run into UB if you compile it without bound 
checking enabled

- when working with arrays or ranges it's better to use unsigned 
integers or just use `size_t` which represents unsigned integer 
for 32 or 64 bit. This avoids negative values and enables the 
maxmium value which can be provided on the plattform to access 
the highest element in the array.

- It's sure advanced topic but you should start to check your 
input from the beginning. Try what happens if you apply negative 
numbers or invalid offsets ;-)

I don't know which client you are using but please have an eye on
