Functions and Random numbers

To gain experience using functions and learn how to generate random numbers.

We will write a game program that allows a person to guess a random number.

Guess My Number Game Enter a guess between 1 and 100 : 4 Too low! Enter a guess between 1 and 100 : 6 Too low! Enter a guess between 1 and 100 : 50 Too high! Enter a guess between 1 and 100 : 25 Too low! Enter a guess between 1 and 100 : 35 Too high! Enter a guess between 1 and 100 : 30 Too low! Enter a guess between 1 and 100 : 32 Too low! Enter a guess between 1 and 100 : 34 Too high! Enter a guess between 1 and 100 : 33 Correct! You got it in 9 guesses!

Questions:

1. How do you generate a number between 1 and 100 (inclusive)?

2. How do you generate a double number between n and m where 0 <= n < m?

Write and test functions:

voidinitRandom();intgetRandomInt(intmin,intmax);doublegetRandomInt(doublemin,doublemax);

Using the functions above write the number guessing game shown in the introduction.

Write a program that generates 100 numbers between 1 and 50. What is the average of these numbers? Can you compute the median of the numbers?
