Questions:
Step1:
Create a routine GetData() to generate a float-point number between
0 and 1 randomly. Since rand() only generate integers from 0 to 32767(i.e.
2^15),to improve the randomness,we use the following scheme:
a□□...□15bits and b□□...□15bits = 30bits (arrays)
The first 15 bits and the latter 15 bits are generated through different
seeds. Then,through a process called normalization,which is to divide the
resulting sequence by 2^30.( Don't use time() )
Step2:
Use the routine GetData() to generate 1000 float-point number data and store
them in a 1-dimensional array named Data{} (maximum capacity 1000).
Please~~
