Which of the following statements is true?
It is considered bad form to give a local variale and a global variable the same name.
Global variables can only be used in a limit of two functions.
Local variables must be declared outside of a function in order to be used.
In order to use a gloval variable in a function, you must pass it in as an argument.
It is considered bad form to give a local variable and a global variable the same name.
The correct statement is:
"Global variables can only be used in a limit of two functions."
To find the correct answer, let's analyze each statement and see if it is true or false.
1. "It is considered bad form to give a local variable and a global variable the same name."
This statement is true. It is generally considered bad practice to give a local variable and a global variable the same name. This is because it can lead to confusion and make the code more difficult to understand and debug.
2. "Global variables can only be used in a limit of two functions."
This statement is false. Global variables can be accessed and modified by any function in a program, not just limited to two functions. A global variable is defined outside of any function, making it accessible and visible to all functions within the program.
3. "Local variables must be declared outside of a function in order to be used."
This statement is false. Local variables are declared inside a function and can only be accessed within that function. They are typically used to store temporary data or intermediate results within the context of a specific function.
4. "In order to use a global variable in a function, you must pass it in as an argument."
This statement is false. Unlike local variables, global variables are accessible directly within any function without the need to pass them as arguments. They are accessible throughout the entire program's scope.
Therefore, the correct statement is: "Global variables can only be used in a limit of two functions."
The statement that is true is:
In order to use a global variable in a function, you must pass it in as an argument.
