Character set for C

Well, I know you are very eager to learn more as you already know the process in last post for making a program, now theoretically i will explain how a program made-

Source Code:- The code we type/write in C language.

Compile:- This is a term to change source code to machinery language and follow the instruction which we asked to computer for. it can be called interpreter.

Object Code:- After compiling the program, the output called object code.

Now ! come to the topic for character set of C language is-

1- Alphabet- A to Z, a to z.

2- Digits- 0 to 9.

3- Special symbols- ~ ' ! @ # % ^ & * () _ - + = | \ {} [] : ; " ' <> , . ? /

Constants- kindly go through with below mentioned fig.

1st- Integer- I think you are well aware about Integer, here in C are few rules for integer value-

- It should be at least one digit, no decimal point, no comma, no blank space.

- unsigned is assumed as positive integer.

- The range for 16 bit compiler for a integer is -32768 to 32767.

for example:-

main ()

{

int a= 12; /* int a is an unsigned integer*/

-------

--------

}

2nd- Real Constants- It also called floats, rules are mentioned below-

- must have a decimal point in a digit and no commas or blank-space allowed.

Example:-

main()

{

float b=1.2e-5;

float a=1.2;
