With the rapid development of computer technology and the lower memory prices, the modern computer, the memory capacity is also increasing, have reached the scope of GB. However, the system software and application software required storage space is also a dramatic expansion of the memory is still no guarantee that there is enough room to save an active process, as well as the operating system required for all programs and data structures. Therefore, the reasonable and efficient allocation and use of memory resources, on the computer a great influence on the performance of the system.
Now, the memory use of technology has become all the programmers have attention. C + + programming language of the dynamic memory mechanism is carried out for flexible program design provides a great convenience, reasonable procedures for the use of memory is to improve the reliability and applicability of an effective method, but it also increased by a variety of memory errors from happening. In this paper, this issue, first of all, summed up the C and C + + dynamic memory allocation function in the use of points, and then summarize and analyze the C + + in the common memory errors, put forward some countermeasures and preventive measures, and finally detected by adding the region, re - containing the new operator to complete the C + + program in the memory part of the detection cross-border issues.
Along with the rapid development of computer technology, the lower prices and memory of the modern computer memory has also increased, has reached the GB range. However, the system software and application software required storage space is sharply, memory is still no guarantee that there is enough space to save active process and operating system needed all programs and data structure. Therefore, reasonable and effective distribution and use of computer memory resources, the performance of the system.
Now, the memory of the use of technology has become all the programmers are ignored. C + + programming language is the dynamic memory mechanism for flexible programs designed to provide convenient and reasonable use a great memory is to improve the reliability and applicability of the program is an effective method, but also increase the chance of various memory error has occurred. This paper firstly summarized the C, C + + and the use of dynamic memory allocation function, and then summarizes and analyzes the common in C + + memory mistake, and puts forward some solving countermeasures and preventive measures, and finally by adding new detection area, overloaded operators to complete C + + program of memory problems.
