Need help with assigning user input

[Mjimmie1]

I know this is a very basic question but it is driving me crazy right now. I Am writing a program to determine the pay of an A, B, or C level author. The user would input the letter of the level and the number of words for the story. The Pay is calculated from there.
**How do I assign the users input to different variables? It shouldn't matter if the letter is capitalized or not. Would I just use a simple if statement?

The code is just an example what I thought assigning the input would look like... skillLvl is the users input

void lvlDetermination(float skillLvl) {
	if (skillLvl == A || a)
		skillLvl = lvlC;
	else if (skillLvl == B || b)
		skillLvl = lvlB;
	else if (skillLvl == C || c)
		skillLvl = lvlC;
	else
		cout << "Please enter the Correct Skill Level Between A and C " << endl;

if (skillLvl == A || a)

That thing on the right. It's NOT "skillLvl is the same as a". It's just "a". I expect you meant:

if (skillLvl == A || skillLvl == a)

Anyway, I think you're maybe asking for something like this:

char skillLvl ;
cin >> skillLvl ;  // ONE character only

if (skillLvl == 'a' || skillLvl == 'A')

Once you get it working, look into http://www.cplusplus.com/reference/cctype/tolower/

OK, I believe I understand what you are are saying. .. So what about the other two Character values? (B, C) Do I have to declare a different variable for each of them or can all input be through "char skillLvl"? Only one will be in use at a time since One character is considered the Authors skill level. So the only time there will be an additional Character is when the program is run again.
