It's mostly about memory access. Modern languages throw errors if, for example, you try to reference an element of an array that is "outside the bounds" of the array. C does not - it gladly returns whatever memory address is past the end of the array. So the programmer has to check that the index is
0 <= x < array_sizewhenever they access a an array entry. That's a pain - so they don't.
