Accepted Answer

In this exercise, we will be working with a series of tasks aimed at implementing a linear-feedback…

// Write your code for Ex 6.1 above this line. // Ex 6.2 // // Write a function called "print_rand" which returns no result // and takes, as a single argument, a pointer to an unsigned 32-bit // integer.
