What are some examples of integer overflow?

What are some examples of integer overflow?

Integer overflow occurs when an arithmetic operation exceeds the maximum limit of an integer type. For example, in a 32-bit signed integer, adding 1 to 2,147,483,647 results in -2,147,483,648.

Can you give me another example?

Sure! If you have an 8-bit unsigned integer, the maximum value is 255. Adding 1 to 255 will cause it to wrap around to 0.

What programming languages are most affected by this?

Languages like C, C++, and Java are particularly affected by integer overflow due to their fixed-size integer types. Python, on the other hand, handles large integers more gracefully.

How can I prevent integer overflow in my code?

You can prevent integer overflow by using larger data types, checking for potential overflows before performing operations, or using libraries that handle big integers.
