婚外情的痛苦:如何编写扑克游戏分牌函数？

取当时的时间作为伪随机数的种子。
初始化状态数组 int sta[54], 全给-1。
初始化排序数组 int order[54],全给-1。
初始化已取得的随机数的个数变量，int NN=0。
初始化54张牌数组 card[54]

while ( NN < 54 ){
产生0到53范围的随机正整数R。
if ( sta[R] == -1) {sta[R] = 1;
order[NN] = R;
NN = NN + 1;
}
}

for (i=0;i<54;i=i+n）{
打印发的牌 card[order[i]];
}
========================================
下面程序，用52张牌，（无大小百搭），4人play
黑桃 SA,S2,S3...SJ,SQ,SK
红桃 HA,H2,...
方块 DA,D2,D3...
梅花 CA,C2,C3...
每局发到手的牌是随机变化的。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>
#include <time.h>
main(int argc, char *argv[] )
{
int i,j,k,n, R;
int sta[52];
int order[52];
int NN = 0;
char *card[52];

for (i=0;i<52;i++) card[i] = (char *) malloc ( 3 * sizeof(char));
for (i=1;i<10;i++) {

sprintf( card[i+13],"H%d",i+1);
sprintf( card[i+26],"D%d",i+1);
