What are local variables in C++ programming?
What are local variables in C++ programming?
Local variables in C++ programming are those variables which have their own boundary and cannot be accessed outside the particular storage boundary.
What is the scope of a local variable in C++ programming?
What is the scope of a local variable in C++ programming?
Local variables have scope limited to the block in which they are declared. They can only be accessed within that block.
Can local variables be accessed outside the block in which they are declared?
Can local variables be accessed outside the block in which they are declared?
No, local variables cannot be accessed outside the block in which they are declared. Their scope is limited to that specific block.

Study Notes
Local Variables in Functions
- Local variables are those that have their own imitation and boundary.
- They cannot be accessed outside the particular imitation storage boundary.
- The boundary of a local variable is the block of code defined by curly brackets
{}
. - A local variable can be used multiple times inside the block.
- Outside the block, the local variable does not exist.
Global Variables in Functions
- Global variables can be accessed throughout the program.
- A global variable can be declared in one part of the program and used in another part.
