C Tokens
Every C program is a collection of instructions and every instruction is a collection of some individual units. Every smallest individual unit of a c program is called token. Every instruction in a c program is a collection of tokens. Tokens are used to construct c programs and they are said to the basic building blocks of a c program.
In a c program tokens may contain the following...
- Keywords
- Identifiers
- Operators
- Special Symbols
- Constants
- Strings
- Data values
In a C program, a collection of all the keywords, identifiers, operators, special symbols, constants, strings, and data values are called tokens.
Consider the following C program...
C program to print all the characters of C character Set
#include<stdio.h>
#include<conio.h>
int main() {
int i;
clrscr();
printf("ASCII ==> Character\n");
for(i = -128; i <= 127; i++)
printf("%d ==> %c\n", i, i);
getch();
return 0;
}
In the above program there are 22 tokens.
