Basic Syntax In C

Now that you know how a C program is put together, it will be easy to understand the other basic parts of the C programming language.

A C program is made up of different tokens. A token can be a keyword, an identifier, a constant, a string literal, or a symbol. As an example, the C statement below is made up of five tokens:

printf("Hello, World! \n");

The individual tokens are −

printf
(
   "Hello, World! \n"
)
;

Semicolons

When you run a C program, the semicolon ends a statement. In other words, there needs to be a semicolon “ ; ” at the end of each statement. It means that a logical entity has come to an end.

Here are two different statements:

printf("Hello, World! \n");
return 0;

Comments

Comments are like notes in a C program; the compiler doesn’t care about them. These characters begin with /* and end with */, as shown below.

/* my first program in C */

Comments can’t be inside of other comments, and they can’t be in a string or a character literal.
