@文心快码[error] declaration of 'a' as multidimensional array must have bounds for al 文心快码 在C/C++中,多维数组声明时必须指定边界,这是由数组的内存布局和访问方式决定的。下面我将分点解释原因,并提供正确的声明示例以及修改用户提供的错误声明。 1. 解释多维数组声明时必须指定边界的原因 内存布局:多维...
Arrays of constant known size can usearray initializersto provide their initial values: inta[5]={1,2,3};// declares int[5] initialized to 1,2,3,0,0charstr[]="abc";// declares char[4] initialized to 'a','b','c','\0'
Even extensions to permit the declaration and use of multidimensional arrays whose size is determined dynamically are not entirely straightforward, although they would make it much easier to write numerical libraries in C. Thus, C covers the most important uses of strings and arrays arising in ...

How about this: for $i ( 0 .. $#AoA ) { $aref = $AoA[$i]; $n = @$aref - 1; for $j ( 0 .. $n ) { print "elt $i $j is $AoA[$i][$j]\n"; } } Slices If you want to get at a slice (part of a row) in a multidimensional array, you're going to have to...
会发现编译都编译不通过,报“[Error] declaration of 'a' as multidimensional array must have bounds for all dimensions except the first”这个错,意思是多维数组的定义必须有一个除第一个之外的所有维度的边界,比如: voidtest1(inta[][5]){for(inti=0;i<5;i++){for(intj=0;j<5;j++){printf("%d...
