• For example, look at the program below. 
• This program is used in the correct order of tokens and nothing but this.

#include <stdio.h> int main()     {         printf(“My Coding Blocks”);         printf(“%d”,5);     }

❖ Tokens are of 6 types. Their list is given below.

• Identifiers
• Keywords

• If you look at this list, then in the above program, int, main, printf, + and software programming is cool etc. everything is tokens only.
• Not just about all these tokens, just being told about identifiers and keywords in this tutorial.
