How to delete a line in a textfile using c++?

[krystalting2]

The program i wrote can run but did not work. I want to delete a line from the textfile "StaffList.txt" but when i cin the name, for example "Ben". After the program ran finished and i open the textfile, the name "Ben" and the whole line is still inside the textfile! I have created the "temp.txt" file before i run the program. Need help!!

//information inside the "StaffList.txt"

The line is not the name.

Since the name is the first part of line you may use substr:

http://www.cplusplus.com/reference/string/string/substr/

like so: if (line.substr(0, name.size()) != name)
