Hello,
I have a command line program which opens other programs. I want to make it multi-threaded so multiple programs can be opened at one time.
Following is my code with using thread. I tried to incorporate threads using this online tutorial, but it did not help. [http://www.computersciencelab.com/MultithreadingTut1.htm]
#include <iostream>
using namespace std;
#include <windows.h>
#include <process.h> // needed for _beginthread()
/**
*
* @return user_input
*/
int user_interface()
{
int user_input = 5;
cout << "What would you like to do?" << endl;
cout << "1) Open Internet Explorer" << endl;
cout << "2) Open Microsoft Word" << endl;
cout << "3) Open Calculator" << endl;
cout << "4) Enter a command" << endl;
cout << "5) Quit" << endl << endl;
cout << "Enter an option number of your choice to perform a task." << endl;
cout << "Invalid option numbers will terminate the program." << endl << endl;
cin >> user_input;
cout << endl;
return user_input;
}
/**
*
* @return 0 - exit program
* 1 - continue
*/
int exec_cmd(int user_input)
{
string cmd;
switch(user_input)
{
case 1:
return 1;
case 2:
return 1;
case 3:
cmd = "calc";
system(cmd.c_str());
return 1;
case 4:
return 1;
case 5:
return 1;
}
return 0;
}
int main (void)
{
int user_input = 0;
int continue_flag = 1;
user_input = user_interface();
// this instruction is for single thread program
exec_cmd(user_input);
// _beginthread( exec_cmd, 0, (int)12 );
// exec_cmd( (int)-5 );
// Sleep(100);
cin.get();
return 0;
}
I have commented out the code that I wrote for multi-threading.
