Results:
With the same variable name, even if the value again, the original occupied space can not be released or replaced, and so the program passive release, the use of time than manual slow.
Below the
temp1= "" ' Switch variable
Temp1 = Space (1024*1024*50) ' 50MB
Change the position of two sentences
Temp1 = Space (1024*1024*50) ' 50MB

After the screenshot 8:
Results:
It can be seen that the active release takes less time than the passive.

Experimental conclusionLab missions (1)1. Write instructions to memory using the e commandFirst use the e command to the memory unit starting from 1000:0 to write the task requirements of the machine code, and then use the R command to see the register status in the CPU, you can see, CS=073FH, ip=0100h, point to memory 073f:0100, and then use the R command to modify CS, IP content, so that CS : IP points to 1000:0. Then use the T command to execute th

The pointer represents an address that can be changed and the array is not available. Uncle names can be used as pointers, and pointer variables can be converted to array form2.

Program analysis: Output is no duplicate number of three digits, then the first should be resolved in an array, a number must not appear two times, then we will write two methods to complete, the first method PrintNum1 first to find out, Then in the definition of a method with a length less than the previous array of arrays GetAr
First, the experimental descriptionA buffer overflow is a scenario in which a program attempts to write to a buffer beyond the pre-allocated fixed-length data. This vulnerability could be exploited by malicious users to alter the flow control of a program, or even execute arbitrary fragments of code. This vulnerability occurs because of a temporary shutdown of the data buffer and the return address, which causes the return address to be overriddenII.

This project aims to provide a easy to use USB experimental board for students of the first year. instead of only using the standard log for their (yet simple) programs, they are able to integrate hardware into their applications, which makes programming more interesting. the project provides a Java API to access the hardware such as display, Flash, ADCs, etc. on the target b
