    Syntax error at end of input

    I'm getting a "Syntax error at end of input" (last line). but i can't find what's wrong.

    Code:
    int main() {
    int ett;
    FILE *filen;
    int val;
    char filnamn[40];
    enum filtyp {db,txt,bin};
    typedef enum filtyp filtyp;
    printf("Skriv filnamn: ");
    scanf("%s", &filnamn);
    int i = 0;
    while( filnamn[i] != '.') {
    i++;
    }
    
    if(filnamn[i+1] == 't' || filnamn[i+1] == 'T' ) { 
    	if((filen = fopen(filnamn, "r")) == NULL) {
            	     printf("file don't exist");
    	     	exit(1);
            	}
            	binary = 0;
    } else if (filnamn[i+1] == 'b' || filnamn[i+1] == 'B') {
    	if((filen = fopen(filnamn, "rb")) == NULL) {
                    printf("file don't exist");
                    exit(1);
                    }
                    binary = 1;
                    }
    
    readfil(filen);
    meny();
    close(filen);
    return 0;
    }

    Well, if you would indent your code properly, you'd see the missing brace...

    Example:

    Code:
    int main( void )
    {
    	if( condition )
    	{
    		foo( );
    	}
    	else if( some_other_condition )
    	{
    		while( true )
    		{
    			bar( );
    		}	
    	}
    }
    Or maybe:

    Code:
    int main( void ) {
    	if( condition ) {
    		foo( );
    	}
    	else if( some_other_condition ) {
    		while( true ) {
    			bar( );
    		}	
    	}
    }
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    Code:
    scanf("%s", &filnamn);
    Don't use an ampersand (&) there. Since filnamn is an array, saying "filnamn" (or equivalently, "&filnamn[0]") gives you a pointer to its first element, which is what you want. No need to get the address of that.

    Consider printing newlines after your "file does not exist" equivalent error messages.

    Also, "close" is a UNIX function for closing files opened with "open"; both of these functions use int file descriptors to refer to files. Since you're using the standard C fopen() which deals in FILE*s, you'll want to use the corresponding fclose() which also uses FILE*s.

    And I hope you're #including at the least stdlib.h (for exit) and stdio.h (for printf etc.).

    Ooh, good catch there dwks.
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    Thanks. I stared at it long enough that I was bound to catch something . . . .

    I guess I could also mention how much easier it would be to assign a variable
    Code:
    const char *mode;
    to either point to the string "r" or "rb", rather than have duplicate fopen() code like that.

    My last note is that declaring variables in the middle of blocks, as the OP has done with
    Code:
    int i = 0;
    is C99 only. You may want to avoid it, it's up to you.
