    NO, sorry, i use "int main()" in normal times.

    I wrote the "void main()" this time is for quick testing.

    I correct it now.

  16. char a[99]; sizeof(a); //

    char a[99];


    sizeof(a); // <<--- How does "sizeof" work to know the no. of elements is 99 ?? I am wondering if there is a place in the memory to store the 99 ??

    OK, well, now I've understood, FAQ:"The return type of main() must always be an int, this allows a return code to be passed to the invoker."

    and ,i'm sorry, , What is the meaning of cast?

    thx.
  18. O~~ thx.. my Eng. is poor.. i want to ask...

    O~~ thx..

    my Eng. is poor..

    i want to ask how C knows that the no. of element is 99 ??

    and ,, can we get 99 in other method of sizeof(a)/sizeof(a[0]) ??

    just want to know..
  19. does C remember the no of elements in the Array??

    int a[99];

    there are 99 (int)s memory allocated.

    why we use sizeof( a ) , it can output 198 ?

    why it knows ? where does it store the no of elements?
  20. How to pass a pointer to a function that can change to addr of the pointer?

    //in this way:


    void ChangeAddr( int **b ){
    *b = (int*) malloc( ... );
    }

    void main(){
    int *a ;
    ChangeAddr( a );
