The book is outdated. Throw it out.

compiling the c and c++ codes

in vi editor:

for c:
in shell :
step 1:type vi <your_program_name>.c
step 2: type gcc <your_program_name>.c -o <your_program_name>.out
or
type gcc <your_program_name>.c -o a.out
step 3:type ./<your_program_name>.out
or
./a.out

for c++:
in shell :
step 1:type vi <your_program_name>.cpp
step 2: type g++ <your_program_name>.cpp -o <your_program_name>.out
or
type g++ <your_program_name>.cpp -o a.out
step 3:type ./<your_program_name>.out
or
./a.out

There are three methods to bulid "C" & "C++" programming in RHL 9.0 & FC .by using GNOME desktop & another in KDE .
There are mainly two editor in GNOME , viz. vi- editor & another is emacs editor.I will discuss both here.



using VI-editor:

1. open terminal .
2. type for C programming
vi <filename>.c

for C++
vi <filename>.cpp

e.g:

vi hello.c { for C}
vi hello. cpp { for C++}

3. then type " i" ( i= insert)
4. then write source code . for details www.howstuffworks.com how to works "C" programming?
5. then press
esc : wq
it is save now.

6. now for comile the programme type,
cc <filename>
7. then for execute type
(dot)/a.out ( dot = . )

8. then it will see your screen.


USING EMACS EDITOR:

1.type emacs<file name> on terminal.
3. then type " i" ( i= insert)
4. then write source code . for details www.howstuffworks.com how to works "C" programming?
5. then press
esc : wq
it is save now.

6. now for comile the programme type,
cc <filename>
7. then for execute type
(dot)/a.out ( dot = . )

8. then it will see your screen.


USING KWRITE IN ( GNOME OR KDE DESKTOP)

1. Open terminal & type kwrite
2. then write source code
3. then click file .
4. then clck save as
5. save the file wtth extension .c/.cpp
now for comile the programme type,
cc <filename>
7. then for execute type
(dot)/a.out ( dot = . )


I hope it will helpful .


If you face any diffuculty u can email me
partha_26786794123@yahoo.com , ( for alert reply here)

partha
I know this is old... But the EMACS help is strange... It describes VI syntax NOT emacs !!

Making executable files for Windows from a C++ program under LINUX

I have a C++ program called estsert.cpp, that estimates the parameters of an AR(p), MA(q) or ARMA(p,q) time series.

The command

g++ estsert.cpp -o estsert

makes the LINUX executable program estsert, and the execution is as we know,


./estsert

If I want to make the executable file on Windows, I need to create using Visual C++ a
new project with the same name (estsert.dsw), and the code
Code:
#include <stdio.h>
#include "sertimp.h"

main()
{int n,i,j,caz,model,ordin,p,q;
 double X[2000],A[100][100],A1[100][100],A2[5][5],coef[5],disper,ldisp[5],lstud[5],rezcrt,disp1[25],
   corel[25],lcov[25],corelp[25],fi[25],AIC1[25],BIC1[25],teta[25],teta1[25][25],aic,bic;

 printf("5--> difference, 6--> correlogram white noise AR(p), 7--> correlogram white noise MA(q), ");
 printf("8--> correlogram white noise ARMA(p,q)\ncaz=");
 scanf("%d",&caz);
 switch(caz)
   {case 2:
       printf("Order of the correlogram=");
       scanf("%d",&ordin);

is copied from the LINUX file copied on memory stick after

// estsert.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
After this I make it executable, and I can run the program on computers that has only Windows as operating system.

My question is if I can make an Windows executable program from a C++ program on LINUX, without accesing a computer with Windows.

Sincerely,
Daniel Ciuiu
