Is my compiler acting up?

When my tutorial is explaining 'char' it shows two pieces of code. I can't run either of them because I get the error "Undefined reference to WinMain@16".....

Code:

---

#include <stdio.h>

int maint()
{
    int cod;
    char c;

    c='a';
    cod = (int) c;
  }

---

and

Code:

---

#include <stdio.h>

int maint()
{
    int cod;
    char c;

    cod=98;
    c= (char) cod;
  }

---

The thing is, I don't really understand char, so I can't really fix it.
Could someone please explain the pieces of code too? Thanks!

My guess if that you've created a Windows project, instead of a Windows Console project.

I never made a choice concerning a project. Though, how do I change the type of project ?

Just to make sure though, you do have a function called main() don't you?

add this before the last brace:

Code:

---

return 0;

---

You've (presumably accidentally) called your main function maint instead of main.

I hate it when that happens!, I finish typing mai- and the compiler suggests maint and I press enter (I always put the brackets later for no reason whatsoever) and yeah... Thanks, now could someone please explain the code?

Explain what?
I see cod, but nothing fishy about it :p

What do you want explaining?

char and int are two C integral types. A char is one byte in size, an int is larger.

You can assign a char to an int no problem, because every value of char will fit in an int.

You can also assign an int to a char, as long as the value is in the appropriate range for a char.

In C, character constants like 'a' are actually an integer of type int, not char. However, 'a' will always fit into a char also, so char c = 'a'; is fine.

On an ASCII system, 'a' will be the int value 97, but C doesn't state that the implementation needs to be ASCII.

Also, it is upto the implementation whether char is to be treated as a signed char, or an unsigned char.

Any other questions?

Yeah, how do you store more than once character in a variable? (With a string?)

A char array. In C, a string is a char array with a null ('\0') character at the end.
