scanf is used for get the values. That is float format string : %f and double format string is : %lf.

since float is represented as f the scanf() statement would be %f
since double can also be represented as long float Lf() scanf statement would be %Lf
so the answer would be 3) scanf("%f %Lf",&a,&b);
