I'm sorry, you must enter a positive integer greater than zer: why?

I'm sorry, you must enter a positive integer greater than zero:-42

I'm sorry, you must enter a positive integer greater than zero: 42

The positive interger was: 42"

I'm supposed to write a program that is supposed to ask for a positive input and if something other than a positive integer is put into the system, it'll keep prompting the user for a positive number. Also attempt to clear the keyboard buffer by reading characters from the keyboard up to and including a new line.

#include<stdio.h>

void loop_trap

int main()
{
   int k = 1;
   do
   {
       printf("Please enter a positive integer: ");
       scanf("%d, &k");
   }
   while (k > 0);
   return 0;
}
if (i <= 0);
{
   printf("I'm sorry, you must enter a positivie integer greater than zero:")

}

Explanation / Answer

#include<stdio.h>
int main()
{
int k;
printf("Please enter a positive integer: ");
   scanf("%d", &k);
   while (1)
{
if(k>0)
{
        printf("The positive integer was: %d ",k);
       break;
   }
       printf("I'm sorry, you must enter a positive integer greater than zero: ");
scanf("%d", &k);   
}
   return 0;
}
