Once you've declared a variable, you can initialize it, which means giving that variable a value. Assigning values to simple variables like numbers is very easy and requires only the assignment operator (=):
int model_year; model_year = 2004; float cost; cost = 1.95;
Although you must declare a variable before assigning a value to it, C does allow you to perform both acts in one step:
int model_year = 2004; float cost = 1.95
Let's build on the previous example by assigning values to the declared variables.
Open var1.c (Script 2.1) in your text editor or IDE.
After declaring the variables but before the return statement, assign each variable a value (Script 2.2):
age = 40; ...
