The main idea: start with the origin and then add an x, Y value each time, find out how many points at the end of the polygon edge, how many internal points, polygon area is how much.Analysis:1, with the lattice point as the vertex of the line segment, the number of points covered is gcd (Dx,dy), wherein, dxdy respectively for the segment of the horizontal and vertical points accounted for. If DX or dy is 0, the number of points covered is dy or dx.2.

The concept of shared memory areas is now extended to include memory areas that are shared between unrelated processes. POSIX provides two ways to share memory areas between unrelated processes :1. Memory mapped file: Opened by the Open function, the resulting descriptor is mapped to a file in the current process address space by the MMAP function. (This is the technique in the previous section)2. Shared Memory Area object: Opened by Shm_open a POSIX

Theorem: For any quadrilateral ABCD, the midpoint of the diagonal line AC and BD is M, N, AB, and CD. verify that the area of the triangle RMN is 1/4 of the area of the Quadrilateral ABCD. Next we will use the C language to verify the correctness of this theorem. Because the computer's accuracy is limited, we use double precision to store the length of each side and the variables in the calculation process,

Input each row is a set of test data, with 6 integer x1,y1,x2,y2,x3,y3 representing the horizontal ordinate of three points, respectively. (Coo

Solving the area (inside the plane) of any polygon and solving the area plane The calculation of the polygon in the plane, that is, the calculation of the polygon in the plane coordinate system. It is known that the coordinates of each point are sequential, clockwise or clockwise. Calculate the area based on the given coordinates. Here is a simple method to cal

The following is a detailed analysis of the differences between the stack area and the heap area memory allocation, the need for friends can come to the referencehas always been the understanding of this problem is hazy, I believe a lot of friends are also like this, always hear the memory will be allocated on the stack, one will be allocated on the heap, then what is the difference between them?

OpenGL Polygon Fill Area function (bottom)In addition to the primitive functions of triangles and general polygons, OpenGL can also describe two types of quadrilateral. the display results of Figure 3.57 (a) can be generated using the Gl_quads entity constant and the 8 vertices specified in the following two-dimensional coordinate array. Glbenin (gl_quads); Glvertex2iv (p1); Glvertex2iv (p2); Glvertex2iv (p3); Glvertex2iv (p4); Glvertex2iv (p5); Glver

1, the stack area (stacksegment)-Automatically allocated by the compiler release, stored function parameters value, local variable value, etc., the system automatically releases the JVM memory resources after the execution of the method is completed.2. Heap area (heapsegment)-typically released by programmers, storing objects and arrays created by new, the JVM does not periodically view this object, and if

Question: starting from a point and eight directions, give the direction of each step and find the area of the polygon formed by the path. However, the question says that we will use the vector cross product to solve the Polygon Area at the beginning and end, and it is not just applicable to convex edges. The concave part is offset by positive and negative.However, this question does not hate precision.Doub

I drew a mind map of the memory area of Java and the main functions of each area.simulating Java heap overflowThe Java heap is used to store object instances. It is only necessary to constantly create objects and ensure that the GC roots between objects has an accessible path to avoid being purged by the recycle mechanism. will be able to simulate a Java heap overflow.

Also known as the method area.The Oracle JDK8 hotspot vm is stripped of "persistent generation" and replaced with "metadata area" (metaspace).Oracle announced the removal of the PermGen memory area when JDK7, but knew JDK8 was eventually removed.Before JDK7, the so-called permanet genera

has always been the understanding of this problem is more hazy, I believe many friends are also like this, always hear the memory will be allocated on the stack, and then in the heap allocation, then what is the difference between them? To illustrate this issue, let's take a look at the organization inside the memory. The above diagram shows that the memory occupied by the program is divided into the following parts. 1, stack area (stacks)The co
