This means that if a function has a local variable called <code>x<\/code>, then another function in the same file cannot access that variable.

Only the function in which they are declared can access them.<\/p>\n<p>Option C is incorrect because values given to local variables are not retained when those parameters go out of scope. The scope of a variable is the part of the program in which it can be accessed. When a function ends, all of its local variables go out of scope and their values are lost.<\/p>\n<p>Option D is incorrect because using local variables does not prevent the program from becoming &#8220;crowded&#8221; with too many variable names. In fact, using local variables can help to make the program more readable and maintainable by reducing the number of global variables that need to be tracked.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on
