应用错误收集

＆lt; p＆gt;所以我试图使用山密码用给定的密钥加密我的3x3矩阵。它适用于第一个输出n的值，它应该是，但是在那个值之后，我得到大的值，它永远不会采用它们的mod。我添加了cout语句来帮助我调试并查看出了什么问题，但我仍然无法修复它。第二个mod 26也在那里，因为当我没有它时，我得到了负13而不是正13.这是一个家庭作业程序，我们的钥匙是作为数字给我们的，以防任何重要。＆LT; / p为H. ＆lt; p＆gt;＆lt; a href =＆＃34; https://i.stack.imgur.com/PDNkO.png" rel =＆＃34; nofollow noreferrer＆＃34;＆gt;＆lt; img src =＆＃34; https：//i.stack.imgur.com/PDNkO.png" alt =＆＃34;在此处输入图像说明＆＃34;＆gt;＆lt; / a＆gt;＆lt; / p＆gt; ＆lt; pre＆gt;＆lt; code＆gt; #include＆lt; iostream＆gt; #include＆lt; string＆gt; #include＆lt; stdio.h＆gt; #include＆lt; ctype.h＆gt; 使用std :: endl; 使用std :: string; void inverse_matrix（）; 字符串加密（字符串x）; int main（） { std :: string one =＆＃34; paymoremoney＆＃34 ;; // inverse_matrix（）; 加密（之一）; 系统（＆＃34;暂停＆＃34）; 返回0; } 字符串加密（字符串x） { int encrypted [4] [4]; int key [3] [3]; key [0] [0] = 4; key [0] [1] = 9; key [0] [2] = 15; key [1] [0] = 15; key [1] [1] = 17; key [1] [2] = 6; key [2] [0] = 24; key [2] [1] = 0; key [2] [2] = 17; int test = 0; char str [] =＆＃34;＆＃34 ;; char c; int length =（int）x.length（）; for（int i = 0; i＆lt; length; i ++） { x [i] = tolower（x [i]）; } / * 而（str [test]） { c = str [test]; 的putchar（tolower的（C））; 试验++; } * / int encrypt [4] [4]; encrypt [0] [0] = x [0]; encrypt [0] [1] = x [1]; encrypt [0] [2] = x [2]; encrypt [1] [0] = x [3]; encrypt [1] [1] = x [4]; encrypt [1] [2] = x [5]; encrypt [2] [0] = x [6]; encrypt [2] [1] = x [7]; encrypt [2] [2] = x [8]; encrypt [3] [0] = x [9]; encrypt [3] [1] = x [10]; encrypt [3] [2] = x [11]; encrypted [0] [0] =（key [0] [0] * encrypt [0] [0]）+（key [1] [0] * encrypt [0] [1]）+（key [3] [ 0] *加密[0] [2]）％26; 加密[0] [0]％= 26; encrypted [0] [1] =（key [0] [1] * encrypt [0] [0]）+（key [1] [1] * encrypt [0] [1]）+（key [2] [ 1] * encrypt [0] [2]）％26; 加密[0] [0]％= 26; encrypted [0] [2] =（key [0] [2] * encrypt [0] [0]）+（key [1] [2] * encrypt [0] [1]）+（key [2] [ 2] * encrypt [0] [2]）％26; 加密[0] [0]％= 26; std :: cout＆lt;＆lt;加密[0] [0]; std :: cout＆lt;＆lt; ENDL; std :: cout＆lt;＆lt;加密[0] [1]; std :: cout＆lt;＆lt; ENDL; std :: cout＆lt;＆lt;加密[0] [2]; std :: cout＆lt;＆lt; ENDL; ＆LT; /代码＆GT;＆LT; /预＆GT; ＆LT p为H.;}＆LT; / p为H.
