Thanks everybody!
Scott, what I want is to let my function by itself get the size of the array, especially when the array size is unknown.
Your explanation about "2" is what I thought, but how come sometime it print 8 elements of the array?
I feel it is related to array and pointer/address, but I could not figure it out myself, especially when google gives many discussions, for example,
this one. but I am still unclear the problem with my code. Thanks a lot again!

Hi !
I'm looking for a way to transform certain floating point numbers in a one-line, variable length file to integers.
I can do this in a crude way with sed :
sed -e 's/0\.\(\):/\1:/g' -e 's/0\.0\(\):/\1:/g' -e 's/1\.000:/100:/g' myfile ... but this doesn't handle the rounding correctly.

template<typename _Tp > class valarray
Detailed Description
Class defining multi-dimensional subset of an array.
The slice class represents a multi-dimensional subset of an array, specified by three parameter sets: start offset, size array, and stride
array. The start offset is the index of the first element of the array that is part of the subset. The size and stride array describe each
dimension of the slice. Size is the number of elements in that dimension, and stride is the distance in the array between successive
elements in that dimension. Each dimension's size and stride is taken to begin at an array element described by the previous dimension. The
size array and stride array must be the same size.
For example, if you have offset==3, stride[0]==11, size[1]==3, stride[1]==3, then slice[0,0]==array[3], slice[0,1]==array[6],
slice[0,2]==array[9], slice[1,0]==array[14], slice[1,1]==array[17], slice[1,2]==array[20].
