Method and system for managing indicator in programming language

Abstract

The invention discloses a method and a system for managing an indicator in programming language. The method comprises the following steps: A) acquiring the value of an indicator; B) judging whether the address position of the indicator exists in an indicator buffer chain table, if yes, executing step C, otherwise, executing step D; C) judging whether a corresponding identification position of the address position and a first integer area of internal memory indicated by the indicator have the same value, if yes, executing step E, otherwise, executing step D; D) feeding back the false value and confirming the indicator as a field indicator; and E) feeding back the true value and presenting that the indicator is effective and usable when the true value is fed back, wherein when the false value is fed back, the indicator is the field indicator and cannot be used. When the result of field indicator is acquired, the internal memory corresponding to the field indicator is released and the node corresponding to the indicator is deleted, thereby eliminating the error access of the field indicator.

Description

technical field [0001] The invention relates to the management of computer pointers, in particular to a method and system for managing pointers in a programming language. Background technique [0002] Computer programming languages ​​generally use C / C++ language or assembly language, and these programming languages ​​all use pointers as a data type. The pointer is the address pointing to a block of memory. It is similar to the house number of a house. The house number is the only way to find the house. After the house is demolished, the house number will not find the corresponding house. The house number at this time is the wild door number No. Correspondingly, the pointer at this time is called a wild pointer. [0003] If the wild pointer is used when the program is running, it will directly cause the program to exit. The exit of the program is the reaction made when the operating system detects an illegal memory operation, because the program runs on the operating system...

AI Technical Summary

Problems solved by technology

[0004] At present, the memory policy of the operating system is to directly kill programs that access wild pointers. In the process of developing programs using C / C++ language, programmers still cannot guarantee that there are no wild pointers in the program by virtue of rigorous logical thinking and detailed testing.
