Question

I want to write a program where it prompts people to enter a set of integers separated by a space. The user should be able to enter any amount of integer. It will find the two smallest integer in the set and print it out. Printing the smallest number and then printing the second smallest. My question is how do I get the value of min1 to be the first integer they enter, other than a static one? When I did a test run all it printed was a space, why is that? Here is what I have so far:

Update:
I’m now trying this approach, but it just freeze after I enter an input such as 76 5 74 2.

#include <stdio.h>

int min1, min2;
int input;

int main(){

  printf("Please enter some integer: ");
  scanf("%d", &min1);
  while(scanf("%d", &input) != 0){
      min1=input;
    }
  printf("%d", min1);
  return 0;
}

Answer 1

You should add \n in the end of the first printf, so it will not buffered.

Also, be care that you work with digits – not integers.

and for your question – just write min1=getchar();.

EDIT: some code that may do what that you want:

printf("Enter numbers. (other chars to end)\n");
int min,input;
scanf("%d",&min);
while (scanf("%d",&input))
 if (input<min)
  min=input;
printf("min: %d\n",min);
