In this homework you will do some statistics of pseudo-random numbers.
C++ provides random numbers via the command int rand() which is from
cstdlib. It will output an integral value between 0 and RAND_MAX.
RAND_MAX is an integer constant coming from cstdlib and the maximum possible random number.
Your assignment is:
- Write a program which creates an array of
N=100random double values between 0 and 1.- The array is to be created in
main, but filling it with random numbers should be done in an extra function. You will need pointers for this.
- The array is to be created in
- Calculate the expected value m and the variance v of your N random numbers x_i, where
* Write one function which calculates *m* and *v*. Your function should return both values to the main program at the same time. Use references for this. The resulting values should be printed in the main program.
