while(i<240)
{

scanf("%s",&lname[i]);

run it if u can and say me whats wrong plzzz! i have to pass this lesson :/

Your compiler tells you what's wrong with it. Go through the error list and fix the errors.

[stamatis]

when i try to compile and run i have this error:
sm=0;
C:\Users\Elena\Desktop\Untitled1.cpp In function `int main()':
49 C:\Users\Elena\Desktop\Untitled1.cpp `sm' undeclared (first use this function)
(Each undeclared identifier is reported only once for each function it appears in.)
and i dont know what to do :/

[Moschops]

You are trying to use a variable sm, in this line:

sm=0;

What is sm? Is it an int? A char? A float? Something else? You never declared it anywhere. It doesn't exist.

Likewise mo, sum, max and les.

As an aside, you're coding in C, not C++.

[stamatis]

i dont know how to fix them.... iam new in C++ :/

[cnoeval]

"sm undeclared" is pretty clear. You initialized the variable sm=0;, but you never declared it at the top. Your compiler doesn't know what type it is so it throws an error.

[Moschops]

int i=0
Do you understand what you did here? What this means? It created an int, called i.

Do you see the difference with this line?
sm=0

[stamatis]

yes! tnx m8! i will try fix it now! tnx!
