Why doesn't format specifier allocate places according to the value given in "Printf" ?

Question

PROGARAM :

float A; A=106.10; printf("Value of A is %5.2f", A);

OUTPUT: Value of A is 106.10

QUESTION: Even if I have given, "%2.2f" instead of "%5.2f", I'm getting the same output.

The value of A will not be displayed/changed according to the format specifier ?

Answer 1

you can write

printf("value of A is %f",5.2*A)

this is correct

Answer 2

in ("%X.Yf" ,A )  -

1. X - determines space occupied by all digits (including decimal) of A

2. Y-  determines space occupied by right hand digit of A.

 case 1.  when X<= actual no. of  digits

             no effect

case 2 .   when  X> actual no. of digits
             displayed digit will be shifted accordingly   i.e.  it will have spaces to left of digit so that

              sum of total space to left of decimal = X.

similarly for RH digits of decimal.
