What impact does overflow have on the results?

The impact of overflow on the results: When the data to be represented exceeds the representation range of the data used by the computer, data overflow will occur, causing data inaccuracy.

Overflow means: when the data to be represented exceeds the range of data representation used by the computer, data overflow occurs.

For example, the defined data type can only store 8 bits. If the value becomes 9 bits, it will overflow.

As for the impact on binary, if it is a signed number, the high bit is the sign bit, and overflow may change the sign of the result. It may also affect the accuracy of the data.

Extended information:

If the data type exceeds the limit of the computer word length, data overflow will occur. There are many reasons for memory overflow problems, such as:

1. Using non-type-safe languages ​​such as C/C, etc.

2. Access or copy the memory buffer in an unreliable way.

3. The memory buffer set by the compiler is too close to the key data structure.

The memory overflow problem is an inherent defect of C language or C language. They neither check array boundaries nor type-safety.

As we all know, programs developed in C/C language can directly access memory and registers because the target code is very close to the machine kernel. This feature greatly improves the performance of C/C language code. As long as it is properly coded, C/C applications are bound to perform better than other high-level languages ​​in terms of execution efficiency.
