Thread: how to stop this proccess prematurely..

i need to enter numbers in a row
of certain length.
if i deside size =3
then i have to input 3 2 7
if i press enter in the middle of the proccess it doesnt stop'
it just enters a new line and continues from there
i want it to sent an error instead.
so if i will press 3 2 enter
it will return an error
i tried to do it here // in the commented line "\n line"
its now working??

Code:

#include <stdio.h>
int read_array(int input[],int i,int size);
 
int main()
{
	int i;
    int input[40];
    printf("%d\n",read_array(input,0,8));
  for(i=0;i<8;i++)
  {
    printf("%d ",input[i]);  
  }
   printf("\n");
}
int read_array(int input[],int i,int size)
{
	int flag,rt;
       
	if (i==size)
	{
     
	   return 1;
	}
     flag=scanf("%d",&input[i]);  "\n line"
	 if (input[i]=='\n')
	 {
        return 0;
	 }
	 if (flag==0)
	 {
		 return 0;
	 }
	 else
	 {
	 }
     rt=read_array(input,i+1,size); 
	 return rt;
}
