   Apr 6, 2023 · Integers in C++ are allocated with a certain number of bits. If an integer value, takes more bits than the allocated number of bits, then we may encounter an overflow or underflow. The integer overflow occurs when a number is greater than the maximum value the data type can hold.

   What is integer overflow & underflow?

   • If an integer value, takes more bits than the allocated number of bits, then we may encounter an overflow or underflow. The integer overflow occurs when a number is greater than the maximum value the data type can hold. The integer underflow occurs when a number is smaller than the minimum value the data type can hold.

   Is it possible to prevent integer overflow?

   • @JohnBollinger yes, but I thought if OP was asking about preventing integer overflow, they would also be interested in floating-point overflow. You cannot prevent integer-overflow completely. If it happens, it happens. You need to be carefully at coding in the first place. But you can try to check before the assignment if an overflow can occur.

   Jun 8, 2021 · One very good way to prevent integer overflows is to use int64_t to implement integers. In most case, 64-bits ints will not commit overflow, unlike their 32-bits counterparts. There is actually very few downsides in using int64_t instead of int32_t.
