3)

a) output:

-8 7 3.5

-8 7 3.5

explanation:

the copy of the variables a,b,c are passed to function f, in parameter.(call by value..)

so, the values changed in f ,will not affect variables, a,b,c..

hence the same values are printed

b)output:

-8 23 10.5
-54 23 31.5

explanation : in function f, the last two parameters(n,w), takes the address of the variables that are passd

whenever the n,w changed in function, f, the corresponding variable values in main also changes..
