Question

The input consists a string and an integer, which are separated by a '/', like this:

hello/17

And I want to read the input into a string and an int, like this:

char str[20];
int num;
scanf("%s/%d", str, &num);  // this how I tried to do it.

I can’t seem to make it, any advice?

Answer 1

scanf awaits a whitespace terminated string when it tries to read %s.

Try to specify the forbidden character set directly:

  scanf("%19[^/]/%d", str, &num);
