Notes for lab 1

In this lab, you will learn C++ by working on exercises. Tasks 01 - 07 are simple tasks to familiarize you to C++ syntax. Tasks 08 - 10 are slightly more problem-solving tasks. As we proceed into the course, you will get more problem-solving tasks.

The following are additional notes for lab 1.

• General notes:
  • Data types: you will see explicitly int and bool. You will also use string constant.

• 01 Hello, C++
  • Pay attention to the comments on namespaces, i.e., the line using namespace std.

• 02 while loop
  • We use cin to read the data from the user.
  • Since we have using namespace std at the top, we can use cout to output integers and endl to force new line.

• 04 check_prime
  • This task shows how to define a function. In C++, you have true and false for bool type.
  • You can use % to mod.

• 05 Next prime
  • In this task, you have to submit the source file.

• 06 Classic stars
  • You can use nested loops. But you don't have to. You can use functions to avoid writing nested loops.

• 08 Close enough
  • Example 1: pairs that are close are (15 - 10), and (15 - 21)
  • Example 2: pairs that are close are (1 - 6), and (6, 11)
