Question

i want to add new rule windows firewall , am using system() function for this in c

normally cmd command for that would be

netsh advfirewall firewall add rule name="myp" dir=in action=allow 
program="C:\test\Project1.exe"

so i want to know how i can insert it to system(); function i try it but no success , i mean double quotes not works like

system("netsh advfirewall firewall add rule name="myp" dir=in action=allow program="C:\\test\\Project1.exe"");

Answer 1

You just need to escape the double quote – \" to use it inside a string.

See here for a list of other escape sequences.

Your command would then become

system("netsh advfirewall firewall add rule name=\"myp\" dir=in action=allow program=\"C:\\test\\Project1.exe\"");
