In the process of learning graphic images, the simplest and most common format is BMP and PPM. The following gives the extremely thin code that generates BMP and then explains the BMP format.1#include 2#include 3 #defineW 2004 #defineH 2005

Small part of the recent efforts to learn C + + Advanced programming knowledge, take advantage of the weekend summed up their own study of the STL algorithm some of the methods, and everyone to share.Non-Modified algorithm:First, For_each

Greedy snakeNow there is a square rectangle of n*m (n,m=100), a random value on each square of the rectangle, a cute little snake starting from the upper left corner of the rectangle, each move can only move one block, to the right or down, and

The #include "stdio.h" \ \ Precompiled command, called a file that contains a file with an. h extension, is called a header file \ \#include "stdlib.h" \ \ contains input and output functions "Putchar", "GetChar", "printf", "scanf" and other

Program at run time, the source of its memory mainly through three methods: Stack data segment, generally speaking, the stack is generally used to store small memory local variables, heap memory and data segment properties are similar, in use, if

Supported but deprecated directives in 1:GCC#pragma pack (): Cancels memory-aligned access#pragma pack (n) (N=1/2/4/8): aligned by N-byte#pragma pack (2) struct mystruct1{int A;char b;short c;} struct mystruct2{int A;; Double B;short C;} #pragma

There seems to be no function in the C + + standard library to split strings. The implementation of a self, the internet search process also found two more interesting segmentation methods.1. Your own simple implementation1 voidSplitConst Char*s,

(1) Break statements are typically used in loop statements and switch statements. When break is used in switch statements, the program can jump out of a switch and execute a switch statement, and if there is no break statement, it becomes a dead
