 Hi.

 How to initialize an array of arrays of ints ?consider the following
sentence:

 int  *numbers[2]  ={
                               { 1 ,2 ,3},
                               {1 ,2 ,3 ,4}
                              };


Here {1 ,2 ,3} and {1 ,2 ,3 ,4} are arrays of integers containing
3 and 4 items respectively and "numbers" is supposed to be an array
of (2) arrays of integers ,but this solution does not work.What
should I do ?

You can only initialize into space that the compiler can reserve statically at compile time. The declaration for your numbers array only allocates two slots in memory for two integer pointers. You must reserve the space for the arrays with the actual numbers first. It could be done something like:

int num1[3] = { 1, 2, 3 };
int num2[4] = { 1, 2, 3, 4 };
int *numbers[2] = { num1, num2 };
