Learning Objective:

student will be able to construct a basic program using variables and displays

Program

Integer Class1, Class2, Class3 Integer average Integer sum Display “Enter the number of students in class 1” Class1 = Input Display “Enter the number of students in class 2” Class2 = Input Display “Enter the number of students in class 3” Class3 = Input Sum = Class1 + Class2 + Class3 Average = sum/3 Display “The sum is “, sum, “ and the average is ”, average

Output

Enter the number of students in class 1
