There is a list of vector operators which you must compute. Each vector operator is written with the following format:
<vector> <operator> <vector>
where a vector is written as [ a1 a2 … an ] (elements are separated together by space), and operator may be *, + or .
For example:
[ 0 1 3 ] * [ 3 1 0 ]
[ 0 1 3 ]  [ 0 1 3 ]
[ 0 1 3 ] + [ 0 1 3 ]
Please write a programme read vectors operators from vector.inp file. After that, evaluate them and write results into output file vector.out:
Input file: vector.inp
The first line writes an integer N which is the number of vector operators. Subsequently, each line in N following lines contains a vector operator. All attributes of vectors are integers in 1000…1000. It is known that all these operators are valid or computable.
Output file: vector.out
For each vector operator in the input, write its result in a line of this output file.
vector.inp
vector.out

[ 0 1 3 ] * [ 3 1 0 ]
[ 0 1 3 ]  [ 0 1 3 ]
[ 0 1 3 ] + [ 0 1 3 ]

[ 0 0 0 ]
[ 0 2 6 ]

§ Try to use the new knowledge which have just learned such as friend class or friend function, or/and overloading operators, …

You didn't actually say what specifically you needed help with, if we just DO your homework for you, you wont actually learn anything. If there is some specific aspect of this confusing you please let us know we'll try to help.
