You can simply use:

while(scanf("%d", &n) == 1)

{

//Do Something

}

You can use a custom input method and check for EOF that is End Of File.

int input()
{

char c;
int flag=0;
c=getchar();
    if(c==EOF)
    return -1;
while(c!='\0')//stop input when null character is encountered meaning a number has ended
{
       //dow what you want
       //save the data or operate on data
   c=getchar();
}
//here return the data acquired
return 0;

}

This will take input character by character . It is upto you how to use those characters . You can transform it into a number or store it as a string and much much more . In the loop in main you can check for if the input () function return -1 to stop executing the program.
