C input

[tomtran3110]

The input has a line of positive integers. You must process all integers in this line.

  while(scanf("%d", &x)){
    //do something
    //terminate condition  //this I want to figure how
  }

I tried scanf("%d%c", &x, &c) and terminate it when c != ' '. But then the input has something like

1 2 3 4 5 

which end with a space then next line.

int x;
while(1l == scanf("%d", &x)) { 
  /* your code here */  
}

It works, tks!! Mind if I ask what does 1l means?
