3、　　编写一个函数。该函数接受下列参数：一个int数组的名称，数组大小和一个代表选取次数的值。然后函数从数组中随机选择指定数量的元素并打印他们。每个元素最多选择一次（模拟抽奖或挑选陪审成员）。另外，请使用time()或其它类似的函数生成种子。以便srand()函数初始化随机数生成器rand()。编写一个简单的程序测试该函数。-The preparation of a function. The function accepts the following parameters: the name of an int array, array size and select the number of a representative value. Function from the array and then randomly select a specified number of elements and print them. Select up to each element of a (simulated draw, or the selection of jury members). In addition, use time () or other similar function to generate the seed. To srand () function to initialize the random number generator rand (). The preparation of a simple procedure to test the function.
