You cannot specifiy width or precision values on numbers that are to be read. The scanf function will attempt to read all valid characters (digits and decimal point) that make up a number, and convert it to the appropriate type. So change your scanf line to:
C++
scanf("%f %f",&num1, &num2);

The precision specifier (%.2f) is used in the 'printf' function instead of 'scanf' to control the number of decimal places when displaying the float values.
For example, %10.4f displays a number at least 10 characters wide in total and four of them are decimal places.

Have also a look at the documentation: function scanf - cppreference[^].
