Synopsis: data_type variable_name = initial_value;

Variable declarations in YCP are similar to C. Before you can use a variable, you must declare it. With the declaration you appoint the new variable to be of a certain data_type which means you can assign only values of that specific type. To avoid any errors caused by uninitialized variables, a declaration must imply a suitable value assignment.

Note: A variable declaration may occur at several points in the code which determines its validity (accessibility) in certain program regions (see Section 8.15, “Variable Scopes and blocks”).

{
    integer int_num     = 42;
    float   float_num   = 42.0;
    string  TipOfTheDay = "Linux is the best!";
    integer sum         = 4 * (int_num + 8);
}
