扑克牌的顺子

//从扑克牌中随机抽5张牌，判断是不是一个顺子，即这5张牌是不是连续的。
//2~10为数字本身，A为1，J为11，Q为12，K为13，而大、小王可以看成任意数字。

#include "iostream"
using namespace std;

//判断,大王小王用0表示 {0, 0, 1(A), 2~10, 11(J), 12(Q), 13(K)}
const int maxLength = 13; //牌的不一样的数最多13个
const int pickNum = 5; //抽取张数，可以改为其他数，增加了程序的扩展性

bool isContinuous(int* nums, int length)
{
int poker[maxLength + 1] = { 0 };
for (int i = 0; i < length; i++)
{
cout << nums[i] << endl;
poker[nums[i]]++;
}

int start = 1;
while (poker[start] == 0)
start++;

int end = start + length;
for (int i = start; i < end; ++i)
{
if (poker[i] == 0)
{
if (poker[0] > 0)
poker[0]--;
else
return false;
}
}
return true;
}

}随机抽牌的程序有点意思。
