Looping through an Array in C with no output

Question

Here is my code:

int main()
{
int tiles[9];
int counter=0;
int i=1;
while (counter<8)
{
    tiles[counter]=i;
    counter=counter+1;
    i=i+1;
    }
int running_total=0;
int current_number;
printf(tiles);

return 0;
}

But I get no output, what is my problem? I'm new to C so I appreciate any comments/criticism.

Edit: I do get an output, but it's a smily face...

Answer 1

1. 如果要打印数字,则需要格式化字符串.

2. 如果要打印数组,则需要循环遍历它.

   int i;
   for ( i = 0; i < sizeof(tiles)/ sizeof(tiles[0]); ++i)
       printf("%d ", tiles[i]); // << added a space for Dietrich Epp :)
