解释“warning: array subscript has type ‘char’”警告的含义 在C或C++编程中,当你看到一个警告“warning: array subscript has type ‘char’”时,这意味着你使用了char类型的变量作为数组的下标。由于char类型在不同的平台上可能默认为signed char,其值范围可能包括负数(例如-128到127,具体取决于编译器和平台...

The array subscript is not part of the variable name. It is only used to display an element of the array. You can also use an array subscript to assign elements of an array. If you type Matrix_1[1,1:20 then the value of the 1st element in Matrix_1 will be changed from 1 to ...
You can access individual array elements through a subscript. The first element of a nonempty array is always at index zero. You can subscript an array with any integer from zero up to, but not including, the count of the array. Using a negative number or an index equal to or greater ...

BC30306: Array subscript expression missing An array initialization leaves out one or more of the subscripts that define the array bounds. For example, the statement might contain the expressionmyArray (5,5,,10), which leaves out the third subscript....
直接翻译成中文是：下标需要数组或指针类型的变量。这是个程序设计上的问题。说白了，就是对于非数组和指针类型的变量，不能用[]这样的下标符号。例如：int x;x[1]=10;就会显示这种错误信息（在C语言中）subscript
