All programming languages have "reserved words". There are usually less than 50 of these reserved words in any given programming language. They are reserved because they have been pre-assigned a specific meaning within that programming language, thus the compiler recognizes those words to mean a specific thing or action. Within C++ the reserved words are also known as "keywords".

 

Programmers use identifier names for a variety of items, to include: functions, variables, named constants, alias names, etc. But, they can't use as identifier names the words that are "reserved to the language".
