o/p of call by reference needed!

Guys I need the o/p of the foll pseudo code in terms if call by reference.Plz ignore the small programmin errors as this a pseudo code not a running code

Code:

SUM(x,y,z)
{
x=y*x;
z=z+x;
}

main()
{
a=3;
b=7;
SUM(b,b-a,a)
printf(a,b,b-a);
}

here a=31,b=28,but what will be the value of b-a will it be 4 which we get after computing the sum function or will it be -3 from the new values of and b(i.e 28-31)



2)

Code:

Code:

value(x,y,z)
{
  x=x*y;
  x=x+y+z;
}

main()
{
 a=3;
 value(a,2*a,a);
 printf("value of a,a);
}
