PDCURSES assignign value to integer make error

Question

I'm using PDCURSES on Windows 7 and my program stops working at the beginning. I noticed the error is made by assigning value to integer in line: 41 . Unfortunately I have no idea why. I'm writing in C in Code blocks. I would be grateful if someone could help me. Error message

Answer 1

Since PDCurses is written in C, I am assuming that you are compiling in C.

Move the

int c; 

to just below the line

char *losowe_nazwy[ILOSC_NAZW]={"JACK","TOM","KEN","JESSY","ANDRIEJ"};
int c; 

The C language expects those sorts of definitions to be at the top of the function.
