Syntax 嵌套循环。最好为i编写对于j…谢谢，是的，我现在看到另一个循环具有正确的缩进，它修复了错误！！！但是，下一个错误“类型向量与字符串文字不匹配”出现在以下行：（X“30”）、--48（X“f6”）、--246（X“108”）、--264。。。。。等等。我知道

嵌套循环。最好为i编写

<代码>对于j

…谢谢，是的，我现在看到另一个循环具有正确的缩进，它修复了错误！！！但是，下一个错误“类型向量与字符串文字不匹配”出现在以下行：（X“30”）、--48（X“f6”）、--246（X“108”）、--264。。。。。等等。我知道这通常是因为我在给整数赋值，比如向量。但是我看不出我在哪里这么做？？有什么想法吗？再次谢谢你，我明白了！是的，在注意到长度不正确后，我实际上将十六进制数更改为12位二进制数，但我不知道必须在向量本身中引用这些数字。我永远也想不到。非常感谢！
