Question

Ok, so still getting use to the basics with processing, and I am unsure if this is the correct way to do multiple arithmetic expressions with the same data, should I be typing each as its own code, or doing it like this?

here is the question;

1. Write the statements which perform the following arithmetic operations (note: the variable names can be changed). (i) a=50 b=60
   c=43 result1 = a+b+c result2=a*b result3 = a/b

here is my code;

short a = 50;
short b = 60;
short c = 43;
int sum = a+b+c; // Subsection i
print (sum);
int sum2 = a*b; // Subsection ii
print (sum2);
int sum3 =a/b; // Subsection iii
print (sum3); 

Answer 1

Using the same variable for a in all three expressions, like you’re doing, is the right way. This means that if you wanted to change a, b, or c you’d only have to change it in one place.
