If a variable is defined inside a function, where can it be accessed outside of that function?

A variable defined inside a function is considered a local variable and is only accessible within that particular function where it was defined. This is due to the principle of variable scope in programming. The local scope restricts access to that variable, meaning that once the function completes execution, the variable ceases to exist outside of that function.

While there are scenarios in which a variable can be accessed outside of its defining function (such as using global variables or returning values), those do not apply when considering a typical local variable defined solely within a function. The concept of scoping ensures that the local variable does not interfere with or is not accidentally overridden by other parts of the program, promoting better organization and modularization of code.
