scanf - C programming - sscanf for tkens separated by space -

i'm trying writing program using c (very new c - been learning 2 weeks), , wanted string of input user stdin, in string has char, followed 2 floats (each has space in between). example be: "y 2.1 1.1". question how can obtain , store 3 inputs, while making sure first char, , following 2 inputs floats?

how can obtain , store 3 inputs, while making sure first char, , following 2 inputs ints?

problem code there spaces @ end, , don't know how rid of it.

a simple way use sscanf() , check if there anything after scanned variable use "%n" record location of scan @ point.

char in1; int in2, in3; int n = 0; sscanf(array,"%c %d %d%n", &in1, &in2, &in3, &n);  if (n > 0 && (array[n] == '\n' || array[n] == '\0')) {   success(in1, in2, in3); } 

it important check results of sscanf(). 1 way check return value should 3 here. unfortunately not tell if exist after in3. setting n == 0 , testing n > 0, code knows scanning proceeded way "%n". code can test character scanning stopped at.
