Week 1 of my journey to write my first iPhone app

I can’t believe that 1 week has gone by already. C is a little harder than I thought. I’ve read the first 8 chapters so I tried to write my first C program. It is a simple random number generator for the lottery. I am still having a couple problem generating numbers that don’t repeat in a list. Here is the code:

#include #include //This is to bring in the declaration of clock() #include //This is to bring in the declarations of srand() and rand()


int		WPicks( void );

int		DPicks( void );

void	Weekly( void );

void	Daily( void );

int		NoSame[100];
int main (int argc, const char * argv[]) {

	srand( clock() );
	Weekly();

	//printf("\n");

	//Daily();
    return 0;

}
void Weekly(){

	int pick, i, j;

	int k;
	for (k=1; k<=1; k++) {

		NoSame[k] = WPicks();

	}

	for (j=1; j<=5; j++){

		for (i = 1; i <= 6; i++) {

			pick = WPicks();

			if ( pick != NoSame[i] )

				NoSame[i] = pick;

			else

				i -= 1;

		}

		for (i=1; i<=6; i++) {

			printf( "%d\t",NoSame[i]);

		}
	printf("\n");
	for (k=1; k<=6; k++) {

		NoSame[k] = 0;

	}	
	}

}
void Daily(){

	int pick, i, j;
	for (j=1; j<=5; j++){

		for (i=1; i<=3; i++) {

			pick = DPicks();

			printf( "%d\t",pick);

		}

	printf("\n");
	}

}
int WPicks( void ) {

	return (rand() % 56)  + 1;

}
