The block storage area requires three terms: ● _ nsconcretstackblock ● _ nsconcretglobalblock ● _ Nsconcretmallocblock The three block storage methods are described as follows: Stack, global, and heap. [Point 1] The block defined outside the function is global. In addition, if the block inside the function does not capture any automatic variables, it is also global. For example, the following code: typedef int (^blk_t)(int);for(...){ blk_t blk = ^(

Understanding heap and stack is helpful for understanding memory management, garbage collection, errors and exceptions, debugging and logs in. NET. The garbage collection mechanism frees programmers from complicated memory management. Although the vast majority of C # programs do not require programmers to manually manage the memory, however, this does not mean that programmers do not need to know how the allocated objects are recycled. In some specia

Calculating a valid arithmetic expression using stack stackQualified Arithmetic expression evaluation problem: a valid arithmetic expression containing "+", "-", "*", "/", positive integers, and parentheses.Arithmetic expressions converted to suffix expressionsIn programming languages, operators are called infix expressions in the middle of two operands, that is, our usual expression methods, such as 1+2*3.In infix expression to consider the priority

after running! big[] "copy" the string "to small[", the results can be imagined. The extra-long data drowns out the memory areas beyond the array, and unpredictable results can occur! The art of buffer overflow attacks is to "turn unpredictable consequences into the results we want!" "For more detailed information about "buffer overflow", please refer to network resources.The following is a debugger to go through the overflow of the program inside to find out.To better demonstrate how the overf

If the task is in the user State when an interruption occursCodeIf the CPU is interrupted, the CPU privilege level changes from 3 to 0. At this time, the CPU will run the switch operation from user-mode stack to kernel-mode stack. The CPU obtains the segment selection and offset of the new stack from the task status segment TSS of the current task. Service Interr
