搜索和删除数组中的函数

我有一个程序用于管理一个名为"client_DB"的记录数据库。数组"client_DB"由客户的手机通话记录组成。每个客户呼叫记录包含八个字段，如下所示：1）十位数的手机号码（字符串，无破折号），2）呼叫中使用的中继站数量（整数），3）以分钟为单位的呼叫长度（整数）；4）呼叫的净成本（双倍）；5）税率（双倍），6）呼叫税（双倍），7）调用的总成本（双）和8）名为"discount_aval"的字符串字段，值为"yes"或"no"。阵列client_DB的容量（SIZE）为20条记录。

它从一个名为"client_data.txt"的输入文件中读取，该文件由以下值组成：

9546321555  0   0   yes
5612971340  5   50  no
3051234567  8   25  no
7542346622  24  17  no
3054432762  15  30  yes
9544321011  50  100 yes
8776219988  87  82  yes
9042224556  4   5   yes
7877176590  11  1   no
5617278899  20  45  no
9546321555  4   3   yes
5612971340  79  86  no
3051234567  8   25  no
7542346622  24  118 no
3054432762  115 25  yes
9544321011  43  10  yes
8776219988  265 22  yes
9042224556  2   5   yes
7877176590  89  67  no
5617278899  40  56  no

我的Remove函数只删除第一个值，如果我键入来删除任何其他值，它根本不会！我的搜索功能只需返回2个数字。这是关了，这不是我想要的。帮助我希望能够向用户请求一个单元号，然后让它搜索整个数组，找到它并删除它。我希望我的搜索也能获取一个输入，找到它，并告诉我它的位置。我试过了，但我不知道我做错了什么。在我的主菜单中，当用户从功能菜单中选择它时，我调用了这两个功能。这是我的代码：
