48 Introduction to C++ Programming and Graphics

• Addition (+): We may write

c=a+b;

• Subtraction (-): We may write

c=a-b;

• Multiplication (*): We may write

c=a*b;

• Division (/): We may write

c=a/b;

• Modulo (%): We may write

c=a%b;

This operator extracts the remainder of the divisiona/b. For example

5%3 = 2

Unconventional operators

In C++, we can write:

a=b=c=0.1;

with the expected result. A perfectly acceptable C++ statement is:

a=1+(b=3);

meaning:

b=3;

a=1+b;

Compound assignation

Other unconventional statements mediated by compound assignation
operators are listed in Table 3.1.1.
