man I forogt what someone said about the cin.getline..
I''m sorry, but I don''t really know what you mean. Did you want to clear the whole screen or just your variables?
Anyway don''t mind me I''ve been up > 24hr and can barley tipe.

well someone told me the code it was like, when it retches the ''\n'' it stops, im getting errors without it and I forgot the code it sucks..

Yes, I remember the topic: Link.
Here is one of my posts on the topic. I think this is the one that you are talking about:
My post:
O.K., I didn't realise that you were using
For your particular code, use this:
If you wanted to know, using
"removes"/"throws away" the newline character from the input queue, allowing you to use
Good luck.
I think this is the one that you are talking about. If not, it is somewhere in the post that I provided a link to.

Here is one of my posts on the topic. I think this is the one that you are talking about:
My post:
O.K., I didn't realise that you were using
std::cin to get user input for an integer before.For your particular code, use this:
std::cout << "Enter Difficulty (1 - 10)\n";
std::cout << "|: ";
std::cin >> Player.diff;
std::cin.get();
std::cout << "\nDifficulty Mode " << Player.diff << 'n';
std::cout << "\nEnter your Force's name\n";
std::cout << "|: ";
std::getline(std::cin, Player.name, '\n');
std::cout << "Squad Name: " << Player.name << "\n";
If you wanted to know, using
std::cin to get an integer leaves a newline character ('\n') in the input queue. std::getline() reads keyboard input until it reaches a newline character. Because a newline character is left in the input queue, std::getline() terminates straight away and the user has no chance to enter input. The line:
std::cin.get();
"removes"/"throws away" the newline character from the input queue, allowing you to use
std::getline() to aquire the name.Good luck.

um, the way cin works, is that it will actually go until it hits any form of white space, space, new line, etc... what cin.getline forces is that you get the entire line, until the character of your choice, in your case the escape sequence for a new line. in your example, you are storing 19 characters into cname, or aname, or until you reach the and basically, if you don''t specify, it looks like it is ''\n'' anyway clicky for all of your getline needs.

A yea secoind squestion why is this switching
iv checked the strings there correct the out come on Game
Data.txt
typed in Commander name: bla bla
typed in Army name: bla bla bla
Gold: 0
Rank: 0
Men: 50
A Men: 0
D Men: 0
Spys: 0
Army Tired: 0
Army Name:
Commander Name: bla bla bla
why is it switching??

You need to call cin.get() everytime between
cin << something;
AND // cin.get() goes here
getline(cin,etc...);
otherwise cin << something; leaves the '\n' in buffer and getline returns immeadiately without actaully getting a line.
So something like this..
