Completion requirements

Exercises 1 to 36 cover basic C++ concepts that you should be able to complete if you have worked through all of the materials in unit 1. Start with some early problems, then try a few from the middle, and then a few more later from the list. Do not attempt any of the problems after Exercise 36, as we haven't learned these concepts yet. Don't worry, we will come back to them.

**1. **Write a program in C++ to print a welcome text in a separate line. **2. **Write a program in C++ to print the sum of two numbers.
