Step By Step
Execution Of C Program
Step 1: Edit
1. This is First
Step i.e Creating and Editing Program.
2. First Write C
Program using Text Editor , such as [ Borland C/C++ 3.0 ,
Notpad++,Notpad
]
3. Save Program
by using [.C] Extension.
4. File Saved
with [.C] extension is called “Source Program“.
Step 2:
Compiling
1. Compiling C Program:
C Source code with [.C] Extension is given as input
to compiler and
compiler convert it into Equivalent Machine Instruction.
2. In Borland
C/C++ 3.0 program can be compiled using key [Alt + F9].
3. Compiler
Checks for errors . If source code is error-free then Code
is
Converted
into Object File [.Obj ].
Step 3: Checking
Errors
1. During Compilation
Compiler will check for error, If compiler finds any error then it will
report it.
2. User have to re-edit
the program.
3. After re-editing
program, Compiler again check for any error.
4. If program is
error-free then program is linked with appropriate libraries.
Step 4: Linking
Libraries
1. Program is
linked with included header files.
2. Program is
linked with other libraries.
3. This process
is executed by Linker.
Step 5: Error
Checking
1. If run time
error occurs then “Run-time” errors are reported to user.
2.
Again programmers have to review code and check for the solution.
