Automatic variables are variables local to a block. They are automatically allocated on the stack when that block of code is entered. When the block exits, the variables are automatically deallocated. Note that automatic variables are often called local variables.

The C storage class for automatic variables is auto; however auto is assumed unless otherwise specified. The basic syntax used to declare automatic variables in C is as follows

[storage_class] data_type variable_1, variable_2, ... variable_n;

An automatic variable will have an undefined value when declared, so it is good practice to initialize it with a valid value before using it.

static char c = 'B';     // static within its declaration scope
 
auto int i1 = 3;         // automatic variable. means, local to its scope

int i2 = -7;             // another automatic variable to the current scope
