COMPUTER 4Q G8

• Global Variables are declared outside any function, they have a global scope and thus are available for any function in the program, including main.
• Local variables are within/inside the function only
• Scope refers to the section of code where a variable is allowed to be accessed or referenced.
• Pass-by-reference method states that parameters that will only accept values from other functions of the program
• Overloading Functions states that it is valid to give several functions the same name, it only has to have a different set of parameters.
• Function overloading allows the function to have many forms
• Function polymorphism allows functions to be overloaded
• • The area of a circle is computed using the equation 3.14*r2(r = radius)​
  • The area of a square is computed using the equation s² (s = length of one side)​
  • The area of a rectangle is computed using the equation 1*w (length x width)​
• Pass-by-value method- Parameters only accept values passed on to them
• Arguments- Values which may be variables passed on to functions
• Function declaration- a way to identify data types
• Class- representation of abstract data
• Constructor- Object of the class is created
• Destructor- Object is destroyed
• Accessor methods- Allow access to data members
