Conversion and calculation of infix expression and suffix expressionDirectory infix expression converted to suffix expression Calculation of postfix expressions 1 infix expression converted to suffix expressionThe infix expression is converted to a suffix expression in the following way: Gets the element of the infix expression in turn, If the element is an operand (number/letter, etc.), the suffix expression is added If the element is an operator, it is presse

How to judge the growth direction of the stack.For a man accustomed to the i386 series of machines, this seems like a boring problem, because the stack is growing from a high address to a low address. However, obviously this is not the purpose of the problem, since the problem is taken out, the question is not only the I386 series of machines, across the hardware platform is the first factor to consider the problem.In an age of great material enrichme

As we mentioned earlier, the switch of the task is the switch of the stack (first of all the task context), and the code simply describes the switching process of the stack switch. However, to successfully switch from one task to another, you must also understand the characteristics of the interrupt processing in the current operating mode of the CPU. For example, what registers will be saved when entering

1. Memory occupied by a c/C ++ compiled program is divided into the following parts:1. stack: the stack zone is automatically allocated and released by the compiler, and stores function parameter values and local variable values. The operation method is similar to the stack in the data structure.2. heap-usually allocated and released by programmers (malloc/free,

1. OverviewIn Java, memory is divided into two kinds, one is stack memory and the other is heap memory.2. Heap Memory 1. What is heap memory? Heap memory is a type of Java memory that is used to store objects and arrays in Java, and when we new an object or create an array, it opens up a space in the heap memory for storage. 2. What are the characteristics of heap memory? 1th: The heap can actually be similar to the pipelin

This article only analyzes the changes in the user stack and kernel stack after the signal is sent to the user program. Without analyzing real-time signals, the entire process is basically the same. Many references 1. A small signal example Hex @ Gentoo ~ /Signal $ cat sigint. c # Include # Include # Include Void sig_int (int signo) { Printf ("hello \ n "); } Int main () { If (signal (SIGINT, sig_in

An English nameHeap and stack are two basic concepts that are often encountered in C/s + + programming. Let's take a look at their English expressions:Heap ――heapStack ――stackTwo two levels of understanding from data structures and systemsThese two concepts are not parallel in a specific C + + programming framework. Deep down to the assembly level, the stack is the data structure provided by the machine sys

The underlying data type is directly allocated in the stack space, and the form parameters of the method are allocated directly in the stack space when the method call is completed and reclaimed from the stack space. The reference data type needs to be created with new, which allocates an address space in the stack spa
