Class plan.png What are we going to learn today?[edit]

  1. Today in class we will focus on conditionals and loops
  2. We will learn about the two types of loops
  3. We will use almost all the conditional operators we can
  4. If time permits, we will COMBINE conditions and loops

Homework.png Homework[edit]

  1. Please write a program which converts a numeric grade to a letter grade
  2. the grade bands work like this:
Numeric grade Letter Grade
0 to 59 F
60 to 69 D
70 to 79 C
80 to 89 B
90 to 100 A

Following is the criteria for a successful program:

  1. Your program must have a variable named $student_score
  2. The variable must be assigned a whole number from 0 to 100
  3. Your program must correctly output the letter grade
    1. if the $student_score variable is between 0 and 59 inclusive, the output should be F
    2. if the $student_score variable is 65, the output should be D
    3. if the $student_score variable is 78, the output should be C
    4. if the $student_score variable is 85, the output should be B
  4. Your program must adhere to our style guide

This homework assignment will be assessed using our Problem set assessment
