• Data can be inform of figure or symbol that are not yet be process or not yet be meaningful to the users.
• Information is a process data that is meaningful to the users.
• Programming language is a language that computer understand e.g c++.

THE HISTORY OF C++
C++ and extension of c was created by James Stroustrup in the year 1980 at bell laboratory. C++ is a hybrid language it's possible to program in either a c like style, and object to be oriented style or both.
C++ is a case sensitive programming that means main () [it expects everything to be in a small letters < lower case >] or else when you have a compelling reason to capitalize something.
VARIABLE
A variable is an object that has name. The word variables is used to suggest that the object value can be changed.

THE RULES OF FORMING A VARIABLES NAME

• A variable name must begin with a letter.
• The period and special data typing character e.g (%, !, #, $.) are not permitted.
• It is good programming practice to avoid the uses of characters under than letter and digit.
• A variables names exceed "255" character.
• C++ distinguish between upper case letters because it is a case sensitive.
• C++ include a number of reserved works (e.g Dim-dimension, If, else, Do etc).
