Compilation Process and Execution of C Programming
Execution is the process of running the program, to execute a 'C' program, we need to follow the steps given below.
COMPILATION PROCESS
EXECUTION
OF A C PROGRAM
Execution
is the process of running the program, to execute a 'C' program, we need to
follow the steps given below.
i)
Creating the Program.
ii)
Compiling the Program.
iv)
Executing the Program.
iii)
Linking the Program with System Library.
i) Creating the Program
Creating
the program means entering and editing the program in standard 'C' editor and
save the program with .C as an extension.
ii) Compiling the Program
This
is the process of converting the high level language program into machine
understandable form (Machine Language). For this purpose Compiler is used.
Usually this can be done in 'C' language by pressing ALT + F9 or choosing
Compile option in the menu system.
Here,
there is a possibility to show errors i.e., Syntax errors, which means the
statements written in program are not in proper syntax.
iii) Linking the program with system library
'C'
Language program is the collection of predefined functions. These functions are
already written in some standard 'C' header files. Therefore before executing a
'C' program, we need to link it with system library. This can be done
automatically at the time of execution.
The
below figure, illustrates the process of creating, compiling and executing a
'C' program.
iv) Executing the Program
This
is the process of running and testing the program with sample data. At this
time, there is a possibility to show two types of errors given below.
a)
Logical Errors: These are the errors, in which the
conditional and control statements cannot end their match after some sequential
execution.
b)
Data Errors: These are the errors, in which the
input data given is not in a proper syntax as specified in input statements.
Usually,
executing the program can be done by pressing CTRL + F9 or choose Run option
from the menu system.
