How to get integer input in an array using scanf in C?

I am taking multiple integer inputs using scanf and saving it in an array

while(scanf("%d",&array[i++])==1);

The input integers are separated by white spaces for example:

12 345 132 123

I read this solution in another post.

But the problem is the while loop is not terminating.

What's the problem with this statement?

OP is using the Enter or '\n' to indicate the end of input and spaces as number delimiters. scanf("%d",... does not distinguish between these white-spaces. In OP's while() loop, scanf() consumes the '\n' waiting for additional input.

Instead, read a line with fgets() and then use sscanf(), strtol(), etc. to process it. (strtol() is best, but OP is using scanf() family)

char buf[100];
if (fgets(buf, sizeof buf, stdin) != NULL) {
  char *p = buf;
  int n;
  while (sscanf(p, "%d %n", &array[i], &n) == 1) {
     ; // do something with array[i]
     i++;  // Increment after success @BLUEPIXY
     p += n;
  }
  if (*p != '\0') HandleLeftOverNonNumericInput();
}
