My C++ program needs to know how many lines are in a certain text file. I could do it with getline() and a while-loop, but is there a better way?

No.
Not unless your operating system’s filesystem keeps track of the number of lines, which your system almost certainly doesn’t as it’s been a looong time since I’ve seen that.
