How 2 run commands having only root privilige in C if one knows the root password?


Suppose I have two accounts: root(obviously the administrator) and user1
Now user1 runs my program(in Qt/C++). This program contains some commands which can be used only by root user.After checking that it is not the root user who has logged in but someone else my program prompts the user to enter the password for root.After taking & verifying that it is the root password, i want that my program should be able to run those commands also.How can i do that?
Thanks in advance

instead of using your program to verify the user has root privelages, you should let the system do it... Use the "switch user" command su or sudo. For the latter, you can place the user in a file called "sudoers" and even name specific commands for which they have root access.
man su
man sudo for more information.
Hope this helps.
