subscript represents the sequence number of the data in the array.
(2) use an array name (such as s) and subscript (such as 14) to uniquely determine the elements in the array. for example, s represents the scores of 15th students.
(3) each element in the array belongs to t
Thinkphp converts a two-dimensional array into a one-dimensional array method applicable to tags. thinkphp dimension. Thinkphp converts a two-dimensional array into a one-dimensional
problem arises. How does a custom function return a two-dimensional pointer, that is, how does a custom function return a shape such as (* P) [N]?How should I declare the pointer? All the experts upstairs have said that the function can only return pointers, but when I try to return a two-dimensional pointer. The compiler still reports an error!Int * ();Void main (){Int B [10] [10] = {10}, (* P1) [10];
