How to Install C and C++ Compilers in Ubuntu and testing your first C and C++ Program

@ Pral
Hey in unix system there are no drive concept (like c:\,d:\ etc). all are these declare as a file system. you can find them at /media/(file system name). you want to paste some .h file? but there are no need for this because ubuntu have preinstall these library files.

It is useful to install manpages in addition to the compilers. You can do this for example using the following command:

sudo apt-get install build-essential manpages-dev

…or if you have already installed the build-essential package:

sudo apt-get install manpages-dev

STEPS TO COMPILE C AND C++ ON UBUNTU

For compilation of c code:
1.Open : applications>accessories>terminal
2.Type the following command in the terminal
gedit name of ur file.c
// I HAVE GIVE MY FILE NAME AS main.c
For me i will type gedit main.c inside terminal
3.Write ur code inside the gedit editor:
#include
#include
int main(int argc, char** argv)
{
printf(“NAMAH SHIVAY\n”);
return 0;
}
4.save the code by pressing ctrl+s
5.In the terminal itself goto :File>Open terminal and do as follows in the newly opened terminal
6.Compile the code using the following command :

cc -c main.c
7.This would produce an object file now you may need to add to the library.
Then create an executable using the following command :
cc -o main main.c
8.Now run this executable using the following command :
./main

sudo aptitude install build-essential will not work any more.you should use sudo apt-get install build-essential

“sudo aptitude install build-essential

This will install all the required packages for C and C++ compilers”

For this do u write that code in the terminal to download the compiler

and if so the terminal says that
the sudo:aptitude: command not found

plzz help ty

guys i think it will works for other versions of ubuntu too

Super helpful. Thanks!

At patricia; Just open up (sudo gedit yourfile.cpp) and keep editing. the built (compiled) version of your code is a different animal all together from the cpp file that you are editing.

try this code:

#include
void main()
{
printf(“hello world!”);
getchar();
}

is the same but you dont have to write “return 0;”
🙂

sorry, I typed as
./MyFirstPointer

bash: ./MyFirstPointer: No such file or directory
it’s what I got!

thank u dude working fine

try,

sudo apt-get install build-essential

Here’s the corrected code:

#include

int main()
{
std::cout << "Hello, world!" << std::endl;
return 0;
}

lot of thanks for helping in installing “build-essential”package now I can make run program in c and c++ from linux
thanx once again

I installed c++ compiler using , sudo apt-get install build-essential

when i type this code i got a message as below, what i must do now
#include
int main()
{
initscr();
move(12,30);
printw(“hello\n”);
getch();
endwin();
return 0;
}

@Suresh,

The “quotes” surrounding “Hello, world” in your printf statement aren’t quotation marks. Be sure you’re composing your code on a text-only editor, such as vi, gedit, Notepad, etc., and not with a word processor such as Microsoft Word. The character you want appears on U.S. keyboards just above the apostrophe, on a key that is just to the left of the Enter key.
