Tokens in C
Every smallest unit used in a C program is a C token such as words, symbols, numbers, etc.
In simple words, whatever words, symbols, numbers are used to create a C program are called C tokens.
C Tokens Examples
printf, void, 34, {, main, etc.
C Tokens Categories
In the C language, C tokens are divided into six below-listed categories/groups.
- Keywords [eg: int, while]
- Identifiers [eg: main, total]
- Constants [eg: 10, 20]
- Strings [eg: “total”, “hello”]
- Special symbols [eg: (), {}]
- Operators [eg: +, /,-,*]
Note: In upcoming chapters, all types of C tokens will be explained in very detail.
How to use C Tokens in the program?
Let’s see how C tokens can be used in a C program.
void main()
{
int a, b, result;
a=20;
b=30;
result=a+b;
printf(result);
}
Example Explained:
In the above example, used C Tokens are..
Keywords → int
Identifiers → main, a, b, result
Delimiter → {,}, (,)
Operators → +
Note: combinedly int, main, a, b, result, {,}, (,), + are called C Tokens.
