Self-Test Exercises 5. Give an expression to produce a pseudorandom integer number in the range 5 to 10 inclusive . 6. Write a complete program that asks the user for a seed and then outputs a list of ten random numbers based on that seed. The numbers should be floating-point numbers in the range to inclusive . .
