A local variable is stored in the stack area, and the memory space is freed after the function call ends.#include"stdio.h"; #include"stdlib.h";int*Getnum () {inti = -; returni;}voidMain () {int*i =Getnum (); printf ("%d\n\r", i);//memory released, incorrect result}The second malloc (memory allocate) dynamically allocates the ram in the heap area, requiring the call free to manually release.the memory reques

The main topic: Starting from the origin, 1-4 respectively, the right down, go right, go right up, go down, 5 means back to the original point, 6-9, go up, left, left, go left. Find out the final polygon area.Analysis: This polygon area is obviously irregular, you can use the vector product directly to find out the area.The code is as follows:--------------------------------------------------------------------------------------------------------------

LeetCode 223 Rectangle Area (rectangular Area)Translation Find the total area of the two intersecting rectangles in the two-dimensional plane. Each rectangle defines the coordinates in the lower left corner and the upper right corner. (For example, a rectangle) assumes that the total floor space will never exceed the maximum value of an int. Original Analysis I

input data with scanf, the output of the calculation results require a text description, take the decimal point after 2 digits. the circumference length, circle area, sphere surface area, sphere volume and cylinder volume are obtained. Program:#include int main (){float H,r,c,s,sq,vq,vz;float pi = 3.141526;printf ("Please input circle radius r, Cylinder high H:");scanf ("%f,%f", r,h);c = 2 * PI*R;s = pi*r*r

This article mainly introduces how to use JavaScript to hide the div area outside the div area. The principle and sample code are as follows. First, let's look at the js event model. The JS event model is bubbling up, for example, after an onclick event is triggered on a DOM element, the event will be propagated along with the node until a click event is bound to a parent node. If the event is not resolved

First: Compatibility: IE6 is a little slow in response, and the effect is not as good as Firefox. The main effect is to imitate the selection area of the Windows desktop. You can use the selection box selection icon. Because there are too many JS Code, only a piece of core code is pasted. JS core code: // Select () {// create a constituency VaR _ down = false for the workspace; var Pos = {X: 0, Y: 0}; var move = {X: 0, Y: 0}; $ (". working "). mous

Source: http://poj.org/problem? Id = 1389 Give some rectangles to calculate the area of these rectangles. A rectangle is the coordinates in the lower left corner and lower right corner. It is a positive integer. Idea: a simple line segment tree question is to find the rectangular area. Because they are all integers and the data range is small, discretization is not required.
