| Abstract: | The essay intensively states the charateristic of the pointers array and its programming application in an effient way. In the development of soft ware, it is always necessary to design a memory buffer with hundreds of KB, which will probably lead to the problem of data span limit in the dvice of C language. The application of the pointers array, however, can solve the above mentioned problem. By means of the pointers array, a sparse array is set up so as to increase the using rate of storage and conveniently realise the operation of access. |
