what is wrong with the one i am working with.

#include <conio.h>
#include <stdio.h>

int main(){

	int num[50], i=0, j, count =0;
	int k, b;

	printf("Enter 0 to exit entering integers.\n\nEnter your integers:\n");

	do{

		scanf("%d", &num[i]);
		i++;
		count++;

	}while(num[i-1]!=0);

        for(j=0; j<=count-2; j++){

            if(k != j){
                num[k] > num[j];
                b = k;
            	//printf("%d", num[k]);
