/*In programming, a "garbage value" refers to the undefined or indeterminate data contained 
in a variable that has not been initialized. This value could be anything that was left in
the memory location designated for the variable, from previous operations or due to other factors.
Garbage values are problematic because they are unpredictable and can cause programs to behave 
inconsistently or crash. They often lead to bugs that are hard to diagnose and fix.*/
