keywords:- every word in a c program is either a keyword or an identifier. All keywords are basically the sequences of characters that have one or fixed meanings. And these meanings in any circumtances , can't be changed. All c keywords must be written in lowercase (small) letters.
eg:- auto, break ,case, char, const, do, if ,double, else .....etc
identifiers:- identifiers r names given to program elements such as variables , arrays & functions. Basically identifers r the sequences of alphabets or digits.
Rules for forming identifier name
* the first character must be analphabet (uppercase or lowercase) or an underscore
* all succeeding characters must be letters or digits.
* no special characters or punctuatio symbols are allowed except the underscore"_".
* no two successive underscores are allowed.
* keywords shouln't be used as identifiers.

Can a reserved word be used as an identifier name?
Identifiers are a bit more generic in the context of programming. If you mean, in terms of the C languages (C, C++, C#), the question is the reverse...keywords may NOT be used as identifiers. For example, you cannot use keywords such as "int", "float", "double", etc. as the names of variables or objects.
What is the identifiers in turbo c?
all keywords
What are the words that make up a high level programming language called?
Some languages have specific terms, however keyword or reserved word is the general terminology we use when referring to a programming language's primary vocabulary. That is; words that cannot be used as identifiers. However, some languages also have contextual keywords. For instance, C++ has final and override contextual keywords. These can be used as both identifiers and keywords, depending on the context. The only reason for this is that people were using these words as identifiers before they were introduced to the language (in C++11) and making them actual keywords would have broken a lot of older code.

1. identifiers beginning with a letter 2. identifiers beginning with an underscore

Differentiate C plus plus and Turbo C?
Turbo C is a software where C or C++ programming environment resides in.But C++ is itself a programming language.
What are the different keyword in C programming Language?
For example 'for' and 'break' are different keywords.
Scanf in java?
There is no scanf in Java. It is one of the keywords used in C Programming language
Is it possible to declare a keyword as an identifier in c plus plus?
No. Keywords are reserved and cannot be used as identifiers. However, C/C++ is case-sensitive. So although register is a reserved keyword, Register is not.
How does the compiler differentiate the statement and function in C programming?
statement should not return a value but function returns a value
A program that executes in c but not in c plus plus?
The logic to create such programs is very simple. We know that rules of programming languages. Among them the most important one is "We should not use keywords as identifiers". Based on this rule we can create many programs that execute in c but not in cpp. Suppose write a program to and two numbers. Store the two values in two variables, name the variables as class and object. then execute in c. it will produce the output, and do the same thing in cpp, it will give two errors. because we used keywords as identifiers in cpp. ex:-#include<stdio.h> #include<conio.h> void main() { int class=10,object=26,res; res=class+object; printf("%d",res); getch(); } Or: char str3[3] = "ABC"; /* doesn't compile in C */
