Variables
Step 2: Initialize a Variable

After we declare a variable, we can give it a value!

Suppose that we have declared an int variable called score, to set it to 0, we can simply write:

score = 0;
  • The score is the name of the variable.
  • The = indicates assignment.
  • The 0 is the value you want to store inside the variable.

Note: In C++, a single equal sign = does not really mean “equal”. It means “assign”. In the code above, we are assigning the score variable a value of 0.
