We have a structure with the following data
Code:
struct athlete
{
    char lastname[40];
    float p1,p2,p3,p4;
};
that corespond to athletes of "Long Jump" that have been done in a competiton.
You must write a program that reads from the keyboard their last name and how far they jumped and save them in a struct.After that the user must be able to print the athletes that jumped more than 7,50(meters).
That insertion of data and the print of them must be done with functions.
The print must include the athlete and all his jumps.
Attention!
If we give negative number or number bigger than 9.50(meters) MUST NOT be accepted
and we repeat the insertion until we have 4 jumps.We accept 0(zero) as a number and means that the jump has been done but was Wrong(failed).


I did my best to translate it, i hope u guys can understand what must be done
I just can't understand structures...
if u know any god tutorial that includes the things i have to do would be great.
I need help fast with this
if u can't understand something let me know
