Does scanf () take '\ n' as the remainder of the previous scanf ()?

Question

In the following C code:

char name[20];
int a;
int b;

for(i=0;i<10;i++)
{
    printf("\nEnter name, a & b: ");
    scanf("%s %d %d",name,&a,&b);
}

reads '\n'in '\n', entered at the end scanf()in the 1st iteration, for the second iterative inputs?

Answer 1

scanfleaves an input stream pointing to \n. In your case, it does not matter: each time it calls, it scanfwill move until it finds the next character without spaces. So give it 10 lines name, a, b, as the input will work as you expect.

But consider the following:

scanf("%d", &a);
fgets(str, 20, stdin);

fgets , , str \n, fgets .
