在通过函数传递整个数组时遇到麻烦

Question

Fairly simple problem I'm having that I can't get my head around. I'm trying to pass an entire array into a function, and it's giving me a syntax error. But I honestly can't see the error, even though it's clearly right in front of me.

Function Declaration:

void insertWholeStruct(StoredData temp[]);

Function Definition:

void Array::insertWholeStruct(StoredData temp[])
{
    for(int i=0;i<arrSize;i++)
    {

        arr[i] = temp[i].id;
        }
    }

Function call, where the error is:

test.insertWholeStruct(testData[]);

Answer 1

只需在函数调用中的testData之后删除[] 。

Answer 2

The error is in the way you try to pass the argument in the function. Your compiler is complaining for not knowing at compile time the size of the array you are trying to pass. Pass by pointer the array and this is alliviated.

It should be instead :

//no need to define pointer name in declaration
void insertWholeStruct(StoredData *);


//function definition should change only a little bit
void insertWholeStruct(StoredData *temp)
{

   for(int i=0;i<arrSize;i++)
   {
       arr[i] = temp[i].id;
   }
}
