%2d means that it will take either one or two digit number. If you enter more than two digits number, it will skip after two digits. If you input 24568, it will skip last three digits and will accept only first two digits i.e 24. %*f means that the input of this variable will be skipped Refer to this section : https://www.sololearn.com/learn/C/2914/

If you have %2d it means it will print integer number with the width at least 2 wide, %.*f will printout float number with the width of 6 numbers after the comma

If you use only %*f in that case you won't get any output
