Well i am a newbie learning c++ these days we are
being thaught on turbo c 3.0 but as like other things
i want to work on c++ in linux .. so i installed gcc
on my linux box but i dont have any idea how to
install it for example i write a program as follows in
turbo c

#include<studio.h>
#include<conio.h>
void main (void)
{
printf("hello world");
}



how do i write the same program in gcc ?
i have tried the same but it gives out error the
#in... files not found 
what can i do & how to compile this program ?

thanks

#include <stdio.h>

int main() {
  printf("hello wordl\n");
}

<stdudio.h> contains a typo

<conio.h> does not exists on Linux. It is not a C or C++ Standard
header file. Furthermore, I doubt that it is necessary at all for
building that program with your Windows compiler.

And now build the program with

g++ myprogram.cpp -o myprogram

Note that you should use 'g++' instead of 'gcc' for building C++
apps. g++ automatically uses some libraries that are often required
for building C++ apps.

It will generate an executable called "myprogram". If "-o myprogram"
were absent it will generate an executable named 'a.out'. It's a valid
executable, despite it's name. Execute your program with

./myprogram

note the ./ It's necessary because, out of the box, most shells does
not looks for executables on the current directory, so you need to say
"execute the 'myprogram' executable which is located on the current
directory"

Hope this helps.

Now execute the command 

info g++

and enjoy the fine manual :-)
