codeBY

2. 3 basic steps in creating an
executable form of a c code
 Writing the c code.
 Compiling the c code.
 Linking the c code with corresponding function.

3. Writing a c code
 The program which we wrote on an editor is known as
source code(high level language code).
 This has an extension .c
 This will be given to compiler before executing.

4. compiling
 In this section an object code(machine level code)
gets generated.
 The object code is independent of errors.
 Soo the compiler identifies the errors and sends error
messages.
 The object code has an extension of .obj

5. Linking
 The object code can’t directly gives results.
 The linker establishes the connectivity between the
library functions and the program.
 And fetches those into a file and it takes name what
we have given.
 It has an extension .exe(windows operating system).
 It has an extension a.out(linx or unix).
 This generates a code executable code.

6.  Let us take a program named sum.
 Sum.c-source code,
 Sum.obj-object code,
 Sum.exe-executable code.
