If you are a developer you need C and C++ Compiler for your development work.In ubuntu you can install the build-essential for C and C++ compilers.
Install C and C++ Compilers in Ubuntu:
[code]sudo aptitude install build-essential[/code]
This will install all the required packages for C and C++ compilers
Testing C and C++ Programs
Compiling Your first C Programs
Now you need to open first.c file
sudo gedit first.c
add the following lines save and exit the file
[code]
#include<stdio.h>
int main(){
printf("hello,world\n");
return 0;
}
[/code]
Firstly compile the code using the following command
cc -c first.c
that would produce an object file you may need to add to the library.
then create an executable using the following command
cc -o first first.c
Now run this executable using the following command
./first
Output should show as follows
Hello, world
Compiling your first C++ program
If you want to run c++ program follow this procedure
g++ is the compiler that you must use.
you should use a .cpp file extension rather than a .c one
You need to create a file
sudo gedit first.cpp
add the following lines save and exit the file
[code]
#include<iostream>
int main(){
std::cout<<"Hello World!" <<std::endl;
return 0;
}
[/code]
Run your C++ Program using the following command
g++ first.cpp -o test
./test
Output should show as follows
Hello World!
