When working with arrays, many programming languages implement array bounds checking to ensure that subscripts used to access elements stay within the defined limits of the array. This crucial feature prevents the program from accessing memory locations that it shouldn't, which can lead to unpredictable behavior or crashes. For instance, trying to access the 10th element of an array that only contains 5 elements would throw an error instead of causing chaos! In languages like C and C++, there isn't built-in bounds checking, which can lead to buffer overrun vulnerabilities. This means developers need to manually validate their array accesses. On the flip side, languages like Python do enforce these checks, leading to safer code at the expense of performance in some cases. Always understand your language's rules to keep your arrays safe and sound!
