The following program compilers and runs without errors. What will the program print out? Show all your computations in details.

Solution

a)

xx=my_fun(xx,k,ypt)

in this function

we are doing x+=5 and returning x*4

initially x is 20 after adding 5 it it 25 and after multiplying with 4 it is 100

hence xx =100

b)Passing by value so value doesnot chnage k=6

c)In function we are doing *fp = float(x)+*fp+5.0

float(x)=25 as we have already incremented x with 5 in previous step

*fp=30

hence *fp=25+30+5=60

we passed reference to the funtion hence value changes
