EC8393 FUNDAMENTALS OF DATA STRUCTURES IN C
2) Compiling the program
The source program statements are translated into object programs.
The translation is done after correcting each statement.
If there is no error, the compilation proceeds and translated program stored in a
3) Linking the program:
Linking keeps all program files and functions required by the program together.
For example if the programmer is using pow() function,then the object code of the function
should be brought from the math library (math.h) of the system and linked to the main program.
4) Executing the program:
After the compilation, the executable object code will be loaded in the computer’s main memory
and the program is executed.
In case of logic or data errors in the program, it would be necessary to correct the source
program or the data, and repeat compiling, linking and executing the program.
The character that can be used to form words,numbers and expressions depend upon the
computer on which the program runs.
The characters in c are grouped into following categories:
1. Letters (Both uppercase letter A to Z ,Lowercase Letter a to z)
2. Digits (number for 0 to 9)
3. Special characters
4. White Space
New line (‘\n’)
