Thread: help with generating numbers

Hi guys,
Im trying to implement a function/program that generates numbers from 1 to the input number given by the user. I've come close to generating all the numbers however there are some duplicates of the numbers still remain.
I just want to generate the number with no duplicates but my algorithm must be wrong, can anyone see anything wrong with what ive done?

Cheers.

Code:

#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#define MAXSIZE 1000
int main()
{
	int k;
	int i;
	int j;
	int num;
	int n=0;
	int tmp[MAXSIZE];
	printf( "Enter integer (max 1000): " );
	scanf( "%d", &k );
	srand(1234567);
	for( i=1; ; i++ ) {
		num = 1+rand()%k;
			for( j=0; j<=MAXSIZE; j++ ) {
				if ( num == tmp[j] )
					break;
				else if ( (num != tmp[j]) ) {
					tmp[n++] = num;
					break;
				}
			}
			
		if ( n==k )
			break;
	}
	
	for( i=0; i<=n-1; i++ )
		printf( "%d ", tmp[i] );
	
	printf( "\n" );
	return 0;
}
