A variable having global scope means _______________.
The correct option is B It can be accessed form any function on the page
A variable having global scope means It can be
accessed form any function on the page.
Global scope refers to any variable that is defined
outside of any function. PHP also stores all global variables in an array
called $GLOBALS[index]. Its index is the name of the variable. This array is
also accessible from within functions and can be used to update global
variables directly.
you should use parseFloat() instead of parseInt().
Because integer number is not decimal. The parseInt() function parses a string and
returns an integer.ParseInt return Only the first number in the string is
returned!. If the first character cannot be converted to a number, parseInt()
returns NaN.
In computer programming, a global variable is a
variable with global scope, meaning that it is visible (hence accessible)
throughout the program, unless shadowed. The set of all global variables is
known as the global environment or global state.
Variables are used to store
data, like string of text, numbers, etc. ... PHP automatically converts the
variable to the correct data type, depending on its value. After declaring a
variable it can be reused throughout the code. The assignment operator ( = )
used to assign value to a variable.
