BIO $480/680$ Computer programming exercise III

This exercise is based on a program that might have been used for our project that tested the random number generator for uniformity. This program is listed on the next page of this exercise. The line numbers have just been added for reference purposes.

What is the purpose of lines $3-5$ in the program?

As noted in the comment in line $7,$ why would we want the system time used as a seed for the random number generator?

The variable number appears in lines $10,11,$ and $13.$ What is this value use for?

The variable count is an integer array. What is it used for in this program? Why does it only need $10$ rows, as indicated in line $11.$

In line $15,$ what is the $"+=1"$ part doing?

$6$ In line $14,$ what is the $"(0,9)"$ part specifying?

Why does line $10$ specify that the variable $x$ has to be an integer variable?

What is the purpose of the for loop in lines $17-18?$ It uses the "range" function. What values does this function return?

What would we have to change to get the program to look at the uniformity over $1000$ random integers?
