Thread: Using variables within system command?

The program seems to run with just the iostream header file on its own, why arent the others required? Just curious

Code:

#include <iostream>
#include <dos.h>
#include <string>

using namespace std;

int select;
string host, msg;
string systemSender = "net send ";



char getinfo()
{
     system("cls");
     cout<< "------------------------\n"
         << "Potato Net Sender v0.01\n"
         << "------------------------\n\n";
     cout<< "Hostname: ";
     cin>> host;
     cout<< "Message: ";  
     getline (cin, msg, '\n');
     cin>> msg;
}

char send()
{
     systemSender += host + " " + msg;
     system(systemSender.c_str());
}

char selection1()
{
            cin.get();
            getinfo();
            send();
}

int exit_app()
{
    return 0;
}

char intro()
{
     system("cls");
     cout<< "------------------------\n"
         << "Potato Net Sender v0.01\n"
         << "------------------------\n\n";
         
     cout<< "1. Send a message to another computer\n"
         << "2. Exit\n\n";
     cout<< "Selection: ";
     cin>> select;
     
     if (select == 1)
     {
            selection1();
     }    
     else if (select == 2)
     {
          exit_app();
     }
     else
     {
         system("cls");
         cout<< "\nYou must enter either 1 or 2 to proceed\n\n";
         cout<< "Press any key to try again...";
         cin.get();
         selection1();
     }
}

int main()
{  
    intro();
    cin.get();
}

Hmm I'm having another slight problem, possibly I'm using the wrong syntax for storing the string into variable msg.

Whenever I type a message with more than one word it will just net send the first word, it doesnt seem to be capturing the whole string.

For Example:

Code:

Hostname: 127.0.0.1
Message: Hello this is a test

That will send only "Hello" through net send.

What else could I use other than system() ? I use it cause its all I know so far, also, I dont quite understand that code you typed, and it gives me the same result as before
