What did I do wrong? I feel like crying.

Question

Each time I use functions, I'm always getting errors I don't understand. The problem is to write a Menu program that a user can select from the list of options. I made it so that if a user enters a number, it says that you entered so and so option. Please don't just correct my code, tell me what I need to learn so that I will know this thing, please. Here is the my code.
#include <iostream>
#include <string>
using namespace std;
string list(char easy, char normal, char hard);
/*char list(string easy, string mormal, string hard);*/
int main()
{
string choice = char list(char easy, char normal, char hard);
cout << "Your option is: " << choice << endl;
return 0;
}
/*string list(string easy, string normal, string Hard)
{
cout << Easy
}*/
string list(char easy, char normal, char hard)
{
char easy;
{
cout << "1. Easy";
cin >> easy;
if (easy == 1)
}
char easy;
char normal;
{
cout << "2. Normal";
cin >> normal;
if (normal == 2)
}
return normal;
char hard;
{
cout << "3. Hard?";
cin >> hard;
if (hard == 3)
}
return hard;
}

Answer 3

I'll start with an advice: do not write a whole program and run it in one step; use many steps, adding one or two lines at every step and running the partial program at the end of every step.
The errors are essentially:
(1) do not input data many times (inside list() once for easy, once for normal, once for hard): you need only one input!
(2) try a better use of brackets:
if (...) }
does not make any sense
(3) remember that for every function there are two different syntaxes: one for declaring it
string list(char easy, char normal, char hard)
and one for calling it
string choice = list(easy, normal, hard)
(4) where are the parameters of list() when you call it? You do not need any parameter
(5) cout requires always a trailing newline (endl), else nothing is printed
Here is your code with corrections:

Answer 4

Bilbo Baggins is right but cout doesn't always require a trailing new line of any type(endl '\n') and it seem you don't know the syntax of "if" statements and codes after an occured return won't run(or even compile in optimized compilation)

Answer 5

I don't know what i'm doing anymore (crying...)

Answer 6

To write better code you should know debugging. Try to understand error which are coming on Console and solve them one by one.
