If you declared a variable as: int x; and did not initialize it, what will its value be when printed?

When a variable of type int is declared but not initialized, its value is considered to be undefined. In many programming languages, including C and C++, local variables that are not explicitly initialized contain garbage values, which means they hold whatever data is currently in that memory location. This can lead to unpredictable results when the variable is printed.

In contrast, if the variable were to be declared at the global or static level, it would automatically be initialized to a default value of 0. However, since the question specifies a local variable declared without initialization, it falls into the category where the value is undefined. The behavior can lead to different outcomes depending on the particular memory state at runtime, emphasizing the importance of initializing variables before use to avoid unintended consequences.
