Generating Poisson and exponential random variables

Most programming languages provide library functions for generating uniform continuous random variable in the range (0,1). However, they often do not provide any functions for generating more complicated types of random variables.

Given a uniform random variable in (0,1), we can generate Poisson and exponential random variables based on their cumulative distribution function. Here is a simple idea. Let's consider, as an example, generating a Poisson random variable with parameter $\lambda =5$.
