Run command in C++

In C++, we can run commands using system() function.

Syntax:

#include 

system("command");

For example, let's say we want to run the "dir" command in Windows:

#include 
#include 
using namespace std;
int main() {

    system("dir");

    return 0;

}

Similarly, we can run other commands too. For example, running the "ls" command in Linux:

#include 
#include 
using namespace std;
int main() {

    system("ls");

    return 0;

}

Note: system() function can be dangerous if used recklessly. Running system() with unsanitized input can potentially allow execution of arbitrary code. So, it's always recommended to use system() function with care and only when necessary.
