The variable declared inside the function is called a variable

The correct answer is local.

Key Points

• A variable declared inside a function is referred to as a local variable.
• Local variables are only accessible within the function where they are declared; they cannot be accessed outside that function.
• These variables are created when the function starts execution and are destroyed when the function ends.
• Local variables are used to store temporary data that is only needed while the function is running.
• Since they are function-specific, local variables help prevent conflicts with variables of the same name in other parts of the program.

Additional Information

• Global Variables:
  • Global variables are declared outside any function and can be accessed and modified from any part of the program.
  • They have a global scope, meaning their value persists throughout the program's execution.
  • While convenient, excessive use of global variables can lead to unintended side effects, making debugging difficult.
• External Variables:
  • External variables are declared using the extern keyword, typically in multiple files.
  • They are used to share data between different files in a program.
  • External variables are not initialized within the file they are declared but are initialized elsewhere in the program.
• Static Variables:
  • Static variables retain their value even after the function in which they are declared has completed execution.
  • They are initialized only once and have a scope limited to the function or file where they are declared.
  • Useful for maintaining state information between function calls.
• Dynamic Variables:
  • Dynamic variables are allocated memory at runtime using functions like malloc() or new in programming languages like C and C++.
  • They provide flexibility in memory management but require explicit deallocation to prevent memory leaks.
