Hello i have a question.
It is possoble in c++ to return a char variable?

for example 
1
2
3
4
5
6
7
8
9
10
11
12
 
char Check(S, n, a){
char OK;
for(int i=0; i<n; i++){
if(something == a){
OK = 'T';
}
else{
OK = 'F';
}
}
return OK;
}

Yes, but if you want this to compile you need to assign 'S', 'n' and 'a' a variable type and declare something.

When you find yourself wanting to ask a question like this, don't. Just compile it and see what happens.

void Maxi2(Skl S[], int n){
	double max = 0.0;
	double max2 = 0.0;
	int ind;
	int ind2=0;
	char skl;
	char skl2 = ' ' ;
	for(int i=0; i<n; i++){
		if(S[i].GetS()>max){
			max2=max;
			ind = i;
			max = S[i].GetS();
			skl = S[i].GetAdress();
		}else if(S[i].GetS() > max2){
			max2 = S[i].GetS();
			ind2 = i;
			skl2 = S[i].GetAdress();
		}
	}
}

And why my program just break when i try to max2=Gets()???

"Gets()" appears to be a member function of the "Skl" data type so you can't use it as a stand alone function.

I dont get it so how it should be written? By the way Skl is my variable so Skl is not a function.

Correct, like I said, it is a data type. The member function of that data type is usually only relevant to a specific instance of that data type.

Unfortunately my crystal ball is broken again, so I can not magically see the code that you wrote for the "Skl" data type and therefore cannot tell you how it should be written nor can I see into your thoughts to tell what it is you are trying to accomplish. If you could post this code along with a brief explanation of what it is you're trying to do then I may be able to help you further.

What kind of limit do you want 'max' and 'max2' to designate?
