why "gets" does not take any input after "scanf" in C language ?

Question

Here is a demo code :
int main()
{
int a;
char str[100];
scanf("%d",&a);
gets(str);
printf("%d",a);
puts(str);
}

output :

Answer 1

you need to input it on the same line, 2 "my name", works fine

Answer 2

It is becasue the gets function reacts on the end of line \n of the previous multi-input.Just add \n into scanf format string just like this:
