linuxmint

I am an absolute beginner with Linux Operating system and just for fun in terminal I typed system() what happened next is as below:

satish@satish-Inspiron-N5010 ~ $ system()
>#include<iostream>
>int main()
bash: syntax error near unexpected token 'int'
satish@satish-Ispiron-N5010~ $

Here I want to know that what is system() ? what is it's role here? why I got error in int main() line? What can we do with C/C++ programming in terminal?

Way to avoid ssh connection timeout & freezing of terminal tab

This is in Ubuntu's Gnome-terminal, though it seems to be pausing the terminal input/output, and doesn't affect the operation… >>> More
