水题一个，就是记录下已经做过了。
题目大意：
给出一个数，问是否能分成两个偶数。
下面是代码：
#include <set>#include <map>#include <queue>#include <math.h>#include <vector>#include <string>#include <stdio.h>#include <string.h>#include <stdlib.h>#include <iostream>#include <cctype>#include <algorithm>#define eps 1e-10#define pi acos(-1.0)#define inf 107374182#define inf64 1152921504606846976#define lc l,m,tr 0 ? (x) : -(x))#define clear1(A, X, SIZE) memset(A, X, sizeof(A[0]) * (min(SIZE,sizeof(A))))#define clearall(A, X) memset(A, X, sizeof(A))#define memcopy1(A , X, SIZE) memcpy(A , X ,sizeof(X[0])*(SIZE))#define memcopyall(A, X) memcpy(A , X ,sizeof(X))#define max( x, y ) ( ((x) > (y)) ? (x) : (y) )#define min( x, y ) ( ((x) <br> <br> <p></p> </algorithm></cctype></iostream></stdlib.h></string.h></stdio.h></string></vector></math.h></queue></map></set>
